好客租房 App 开发

练习 dart 语言的插件

下载安装dart sdk(网址:http://www.cndartlang.com/920.html),下载vscode插件(code runner),dart 文件右键运行即可.

开始项目创建

项目【菜单】— 【查看】—【命令面板】— 【Flutter：New Project】测试页面代码:lib/main.dart

import 'package:flutter/material.dart';
void main ()=>runApp(MyApp());
class MyApp extends StatelessWidget{
  @override
  Widget build(BuildContext context){
    return MaterialApp(
      home:Scaffold(
        appBar: AppBar(
          title:const Text("Home")
        ),
      )
    );
  }
}

运行命令,在终端按 r 会自动刷新模拟器界面.

flutter run

编写一个简单页面-实现

效果：

步骤：

添加 PageContent 组件(安装 Awesome Flutter Snippets 插件有快捷键)
1. 新建文件 /widgets/page_content.dart
2. 添加 material 依赖;//importM
3. 编写无状态组件//StatelessW
4. 添加 name 参数 //起类名 PageContent ,声明 name:final String name;点击快速修复生成构造函数
5. 使用 Scaffold //返回一个 Scaffold
添加 HomePage 页面
1. 新建文件 /pages/home/index.dart
2. 添加 material, page_content 依赖//import 'package:first_flutter_app/widgets/page_content.dart';
3. 编写无状态组件
4. 使用 PageContent
添加 Application 应用根组件
1. 新建文件 /application.dart
2. 添加依赖和 HomePage 界面引入 //可以点击组件后用 ctrl+单击自动引入
3. 使用 MaterialApp //在 main 里导入 Application
测试

路由配置

安装(如果安装不了,可以参考我的另一篇博客方法https://blog.csdn.net/xiaodi520520/article/details/99672182)

dependencies:
// 下面有空格,安装好后再通过.lock文件吧版本号写回去
fluro: any

添加 /pages/login.dart
参考 /pages/home/index.dart 完善登陆页。
在 application 里把入口文件改成 loginPage

配置步骤

步骤：

创建 routes.dart 文件并编写 Routes 类的基本结构
定义路由名称

static String home="/";
static String login="/login";

定义路由处理函数

//fluro官网有介绍
static Handler _homeHandler = Handler(handlerFunc: (BuildContext context, Map<String, dynamic> params) {
return HomePage();
static Handler _loginHandler = Handler(handlerFunc: (BuildContext context, Map<String, dynamic> params) {
return LoginPage();

编写函数 configureRoutes 关联路由名称和处理函数

 static  void configureRoutes(Router router) {
router.define(home, handler: _homeHandler);
router.define(login,handler:_loginHandler);

在 Application 中引入和调用路由

import 'package:goodhouse/routes.dart';
   Router router=Router();
 Routes.configureRoutes(router);

测试路由在 page_content 文件中添加按钮查看效果.

 FlatButton(child:Text(Routes.home),onPressed:(){
         Navigator.pushNamed(context,Routes.home);
       }),
       FlatButton(child:Text(Routes.login),onPressed:(){
         Navigator.pushNamed(context,Routes.login);
       }),

优化路由(参数传递)

带参数页面处理

在 /pages 目录添加 room_detail/index.dart 文件
实现 RoomDetailPage
在 /routes.dart 添加 _roomDetailPage
在 /routes.dart 的 configureRoutes 中添加 RoomDetailPage;
修改 PageContent 测试

登录页面

scafford

appBar
title— Text
body
用户名— TextField
密码— TextField
登陆按钮— RaisedButton
注册链接— Row[Text,FlatButton]

添加密码显示与隐藏

将无状态组件改成有状态组件— 快速方法组件名右键重构
添加可点击的图标— IconButton

TextField(
         decoration: InputDecoration(
           labelText:"密码",
           hintText:"请输入密码",
           suffixIcon:IconButton(icon:Icon(
             showPassword?Icons.visibility_off:Icons.visibility
           ),
            onPressed: (){
              setState(() {
                showPassword=!showPassword;
              });
            }) //使用文本框 TextField 自带的属性【后缀图标 suffixIcon】
         ),
       ),
````

3. 添加状态— showPassword

```js
bool showPassword=false;

根据状态展示不同内容
给图标添加点击事件
测试

细节优化

边距/异形屏幕问题？使用 SafeArea(解决超出问题)

minimum: EdgeInsets.all(30.0); //解决padding问题

垂直高度不足问题？使用 ListView(不够可以滚动) 替代 Column

添加注册页面

步骤：

添加文件 /pages/register.dart
将 login.dart 文件拷贝到 register.dart
修改类名称
修改 title
在路由中添加 register
1. 添加 route name
2. 添加 route handler
3. 在 configureRoutes 中关联 name 和 router
修改了组件类型，需要重启 app 后测试

注册页面优化

步骤：

删除密码显示逻辑
添加确认密码
修改按钮及下方链接到文案
优化登陆注册跳转，使用 Navigator.pushReplacementNamed

Navigator.pushReplacementNamed(context, "login"); //可以删除记录

首页开始

参考pubpacka官方代码: (注意我的环境有两处要改)

// fontSize: 30
   fontSize: 30.0
// selectedItemColor: Colors.amber[800],
   fixedColor:Colors.blue,

修改后的代码如下:

import 'package:flutter/material.dart';
import 'package:goodhouse/widgets/page_content.dart';

// 1. 需要准备 4 个 tab 内容区（tabView）
List<Widget> tabViewList = [
  PageContent(name: '首页'),
  PageContent(name: '搜索'),
  PageContent(name: '咨询'),
  PageContent(name: '我的'),
];

// 2. 需要准备 4 个 BottomNavigationBarItem
List<BottomNavigationBarItem> barItemList = [
  BottomNavigationBarItem(title: Text('首页'), icon: Icon(Icons.home)),
  BottomNavigationBarItem(title: Text('搜索'), icon: Icon(Icons.search)),
  BottomNavigationBarItem(title: Text('咨询'), icon: Icon(Icons.info)),
  BottomNavigationBarItem(title: Text('我的'), icon: Icon(Icons.account_circle)),
];

// 3. 编写有状态组件
class HomePage extends StatefulWidget {
  HomePage({Key key}) : super(key: key);

  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  int _selectedIndex = 0;
  void _onItemTapped(int index) {
    setState(() {
      _selectedIndex = index;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body:tabViewList[_selectedIndex],
      bottomNavigationBar: BottomNavigationBar(
        type: BottomNavigationBarType.fixed,
        items: barItemList,
        currentIndex: _selectedIndex,
        fixedColor: Colors.green,
        onTap: _onItemTapped,
      ),
    );
  }
}

首页第一屏页面

底部 tab 实现

步骤：

新建文件 /pages/home/tab_index/index.dart
添加依赖，编写无状态组件
简化实现顶部区域--appBar
body 部分包含多个组件且可以滚动—使用 ListView
在 home/index.dart 中使用 TabIndex 组件

List < Widget > tabViewList = [
  TabIndex(),
  // PageContent(name: '首页'),
  PageContent((name: "搜索")),
  PageContent((name: "咨询")),
  PageContent((name: "我的"))
];

轮播图的实现

步骤：

准备组件框架代码
1. 新建文件 /widgets/common_swipper.dart
2. 添加依赖 material 和 flutter_swiper
3. 准备图片数据
4. 编写无状态组件
5. 添加 images 参数并在构造函数中赋值
编写 swiper 核心代码
1. 参照官网使用 swipper
2. 修改 itemBuilder 和 itemCount
3. Swiper 父组件指定高度
```
//父组件获取屏幕高度的固定方法
var width = MediaQuery.of(context).size.width;
```
测试
1. 在 tabIndex 中使用 CommonSwiper

首页导航

1.数据准备

import 'package:flutter/material.dart';

//准备数据:title,image
class IndexNavigatorItem {
  final String title;
  final String imageUrl;
  final Function (BuildContext contenxt) onTap;
  IndexNavigatorItem(this.title,this.imageUrl,this.onTap);
}

List<IndexNavigatorItem> indexNavigatorItemList=[
  IndexNavigatorItem('整租','static/images/home_index_navigator_total.png',(BuildContext context){
    Navigator.of(context).pushNamed('login');
  }),
  IndexNavigatorItem('合租','static/images/home_index_navigator_share.png',(BuildContext context){
    Navigator.of(context).pushNamed('login');
  }),
  IndexNavigatorItem('地图找房','static/images/home_index_navigator_map.png',(BuildContext context){
    Navigator.of(context).pushNamed('login');
  }),
  IndexNavigatorItem('去出租','static/images/home_index_navigator_rent.png',(BuildContext context){
    Navigator.of(context).pushNamed('login');
  }),
];

添加依赖 material 和 index_navigator_item
编写无状态组件
完成页面结构

import 'package:flutter/material.dart';
import 'package:goodhouse/pages/home/tab_index/index_navigator_item.dart';
class IndexNavigator extends StatelessWidget {
  const IndexNavigator({Key key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Container(
      padding:EdgeInsets.only(top:6.0,bottom:6.0),
      child: Row(
        mainAxisAlignment: MainAxisAlignment.spaceAround,
        children: indexNavigatorItemList
        .map((item)=>InkWell(//InkWell可以实现水波纹效果
          onTap: (){
            item.onTap(context);
          },
          child: Column(
            children:<Widget>[
              Image.asset(item.imageUrl,
              width:47.5,),
              Text(item.title,style:TextStyle(
                fontSize: 14.0,
                fontWeight: FontWeight.w500
              ))

            ]
          ),
        )).toList()//转化成List
      ),
    );
  }
}

使用图片缓存进行封装

步骤：

准备
1. 安装 flutter_advanced_networkimage: ^0.5.0 依赖
2. 添加文件 /widgets/common_image.dart
3. 引入两个依赖
4. 编写正则根据图片地址判断是网络图片还是本地图片
```
final networkUrlRef=RegExp('^http');//网络图片
final localworkUrlRef=RegExp('^static');//本地图片
```

编写框架代码
1. 编写无状态组件
2. 完善组件参数 src width height fit
完成核心逻辑
1. 如果是网络图片，使用 flutter_advanced_networkimage
2. 如果是本地图片，使用 Image.asset
3. 返回 Container

import 'dart:html';
import 'package:flutter/material.dart';
import 'package:flutter_advanced_networkimage/provider.dart';

final networkUrlRef=RegExp('^http');//网络图片
final localworkUrlRef=RegExp('^static');//本地图片

class CommonImage extends StatelessWidget {

 final String src;
 final double width;
 final double height;
 final BoxFit fit;//图片的适应模式类型

const CommonImage({this.src,Key key,  this.width, this.height, this.fit}) : super(key: key);//把this.src放在最前面



 @override
 Widget build(BuildContext context) {
  if(networkUrlRef.hasMatch(src)){//正则判断是否网络图片
    return Image(
      width: width,
      height: height,
      fit: fit,
      image: AdvancedNetworkImage(
        src,
        useDiskCache: true,//磁盘缓存
        cacheRule: CacheRule(maxAge:Duration(days:7)),//保存时间
        timeoutDuration: Duration(seconds: 20)//超时时间
      ),
     );
  }
  if(localworkUrlRef.hasMatch(src)){
    return Image.asset(
      src,
      width: width,
      height: height,
      fit: fit,
    );
  }
  assert(false,"图片地址不合法");//抛出异常
  return Container();


 }
}

使用 CommonImage

CommonImage((src: item.imageUrl), (width: 47.5));

首页-tabIndex-推荐-准备

1.数据准备

class IndexRecommendItem{
   final String title;
   final String subTitle;
   final String imageUrl;
   final String navigateUrl;
   const IndexRecommendItem(this.title,this.subTitle,this.imageUrl,this.navigateUrl);
}

const List<IndexRecommendItem> indexRecommendData=[
  const IndexRecommendItem(
    '家住回龙观','归属的感觉', 'static/images/home_index_recommend_1.png', 'login'),

  const IndexRecommendItem(
    '宜居四五环', '大都市生活','static/images/home_index_recommend_2.png', 'login'),

  const IndexRecommendItem(
    '喧嚣三里屯', '繁华的背后','static/images/home_index_recommend_3.png', 'login'),
  const IndexRecommendItem(
     '比邻十号线','地铁心连心', 'static/images/home_index_recommend_4.png', 'login'),
];

步骤：

准备
1. 使用上一节准备好的数据
2. 新建文件 pages/home/tab_index/index_recommond.dart
编写核心代码
1. 添加依赖，无状态组件，dataList 参数，indexRecommendData 改成常量
2. 添加背景色及边距
3. 添加 wrap
测试

import 'package:flutter/material.dart';
import 'package:goodhouse/pages/home/tab_index/index_recommond_data.dart';
class IndexRecommond extends StatelessWidget {
  final List<IndexRecommendItem> dataList;

  const IndexRecommond({Key key,this.dataList=indexRecommendData}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Container(
      padding: EdgeInsets.all(10.0),
      decoration: BoxDecoration(color: Color(0x08000000)),
      child: Column(
        children:<Widget>[
          Row(
            mainAxisAlignment:MainAxisAlignment.spaceBetween,
            children:<Widget>[
              Text('房屋推荐',style:TextStyle(
                color:Colors.black,
                fontWeight:FontWeight.w600,

              )),
              Text('更多',style:TextStyle(
                color:Colors.black54
              ))
            ]
          ),
          Padding(padding: EdgeInsets.all(5),),
          Wrap(
            spacing: 10.0,
            runSpacing: 10.0,
            children:dataList.map((e) => Container(
                width: (MediaQuery.of(context).size.width -30.0)/2,
                height: 100.0,
                decoration: BoxDecoration(color:Colors.red),
              )).toList()
          ),
        ]
      ),
    );
  }
}

优化提取 item

import 'package:flutter/material.dart';
import 'package:goodhouse/pages/home/tab_index/index_recommond_data.dart';
import 'package:goodhouse/widgets/common_image.dart';

var textStyle=TextStyle(fontSize:14.0,fontWeight:FontWeight.w500);

class IndexRecommendItemWidget extends StatelessWidget {
  final IndexRecommendItem data;

  const IndexRecommendItemWidget(this.data, {Key key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return GestureDetector(//手势组件
      onTap: (){
        Navigator.of(context).pushNamed(data.navigateUrl);
      },
      child: Container(
        decoration: BoxDecoration(
          color:Colors.white,
        ),
        width:(MediaQuery.of(context).size.width-30.0)/2,
        padding: EdgeInsets.all(10.0),
        child:Row(
          mainAxisAlignment: MainAxisAlignment.spaceAround,
          children:<Widget>[
            Column(
              children: <Widget>[
                Text(data.title,style:textStyle),
                Text(data.subTitle,style:textStyle),
              ],
            ),
            CommonImage(src:data.imageUrl,width:55.0)
          ]
        )
      ),
    );
  }
}

资讯部分

数据准备 home/info/data.dart

// 资讯数据准备,注意下面的格式

class InfoItem {
  final String title;
  final String imageUrl;
  final String source;
  final String time;
  final String navigateUrl;
  const InfoItem(
      {this.title, this.imageUrl, this.source, this.time, this.navigateUrl});
}

const List<InfoItem> infoData = [
  const InfoItem(
      title: '置业选择 | 安贞西里 三室一厅 河间的古雅别院',
      imageUrl:
          'https://wx2.sinaimg.cn/mw1024/005SQLxwly1g6f89l4obbj305v04fjsw.jpg',
      source: "新华网",
      time: "两天前",
      navigateUrl: 'login'),
];

内容编码 info/index.dart

import 'package:flutter/material.dart';
import 'package:goodhouse/pages/home/info/data.dart';
import 'package:goodhouse/pages/home/info/item_widget.dart';

class Info extends StatelessWidget {
  final bool showTitle;//考虑到资讯和首页有些显示,所以采用复用
  final List<InfoItem> dataList;

  const Info({Key key,this.showTitle=false, this.dataList=infoData}) : super(key: key);//infoData是data.dart文件内容


  @override
  Widget build(BuildContext context) {
    return Container(
      child: Column(
        children:<Widget>[
          if(showTitle)Container(
            alignment:Alignment.centerLeft,
            padding:EdgeInsets.all(10.0),
            child:Text('最新资讯',style:TextStyle(color:Colors.black,fontWeight:FontWeight.w600))
          ),
          Column(
            children:dataList.map((myitem) =>

            //  Container(
            //   height:100.0,
            //   margin:EdgeInsets.only(bottom:10.0),
            //   decoration:BoxDecoration(color:Colors.red),
            // )
            ItemWidget(myitem)
            ).toList(),
          )
        ]
      ),
    );
  }
}

子选项内容 info/item_widget.dat

import 'package:flutter/material.dart';
import 'package:goodhouse/pages/home/info/data.dart';
import 'package:goodhouse/widgets/common_image.dart';

class ItemWidget extends StatelessWidget {
  final InfoItem data;
  const ItemWidget(this.data,{Key key}) : super(key: key);//记住this.data一定要在前面,并且和后面对象独立

  @override
  Widget build(BuildContext context) {
    return Container(
      height: 100.0,
      padding: EdgeInsets.only(left: 10.0, right: 10.0, bottom: 10.0),
      child: Row(
        children: <Widget>[
          CommonImage(
            src: data.imageUrl,
            width: 120.0,
            height: 90.0,
          ),
          Padding(
            padding: EdgeInsets.only(left: 10.0),
          ),
          Expanded(
              child: Column(
                  mainAxisAlignment: MainAxisAlignment.spaceBetween,
                  children: <Widget>[
                Text(data.title,
                    style: TextStyle(
                        fontWeight: FontWeight.w600, color: Colors.black)),
                Row(
                  mainAxisAlignment: MainAxisAlignment.spaceBetween,
                  children: <Widget>[
                    Text(data.source, style: TextStyle(color: Colors.black54)),
                    Text(data.time, style: TextStyle(color: Colors.black54))
                  ],
                )
              ])) //Expanded自动填充组件
        ],
      ),
    );
  }
}

首页资讯 tab_info 页面

创建 tab_info/index.dart 文件,复用 info 文件内容渲染即可在 home/index.dart 中将第三个资讯 tabViewList 改为 TabInfo().

首页搜索页面

数据准备:tab_search/dataList.dart 步骤：

创建文件 /pages/home/tab_search/dataList.dart 使用上一节准备的数据
创建文件 /pages/home/tab_search/index.dart
引入依赖，创建有状态组件
编写主体结构(使用列表组件和搜索组件分离)

import 'package:flutter/material.dart';

import 'dataList.dart';

class TabSearch extends StatefulWidget {
  const TabSearch({Key key}) : super(key: key);

  @override
  _TabSearchState createState() => _TabSearchState();
}

class _TabSearchState extends State<TabSearch> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('tabSearch'),),
      body: Column(children: <Widget>[
        Container(
          height: 40.0,
          child: Text('filterBar'),),
          Expanded(child: ListView(
            children: dataList.map((item)=>Container(
              height: 200.0,
              margin: EdgeInsets.only(bottom: 10.0),
              decoration: BoxDecoration(color: Colors.grey),
            )).toList(),
          ),)
      ],),

    );
  }
}

然后封装 item 和 tags: common_tag.dart(中间用工厂构造函数)/room_list_item_widget.dart 工厂函数用法：

import 'package:flutter/material.dart';
class CommonTag extends StatelessWidget {
  final String title;//这是外部传递过来的
  final Color color;//自己的
  final Color backgroundColor;
  const CommonTag.origin(this.title,{Key key,this.color=Colors.black,this.backgroundColor}) : super(key: key);//注意外部和自己的写法

  // 工厂函数
  factory CommonTag(String title){
    switch (title) {
      case '近地铁':
      return CommonTag.origin(
        title,//title子不变，其它值都改变
        color:Colors.red,
        backgroundColor: Colors.red[50],
      );
      case '集中供暖':
      return CommonTag.origin(
        title,//title子不变，其它值都改变
        color:Colors.blue,
        backgroundColor: Colors.blue[50],
      );
      case '新上':
      return CommonTag.origin(
        title,//title子不变，其它值都改变
        color:Colors.green,
        backgroundColor: Colors.green[50],
      );
      case '随时看房':
      return CommonTag.origin(
        title,//title子不变，其它值都改变
        color:Colors.orange,
        backgroundColor: Colors.orange[50],
      );

      default:
      return CommonTag.origin(title);
    }
  }


  @override
  Widget build(BuildContext context) {
    return Container(
      margin: EdgeInsets.only(right:4.0),
      padding: EdgeInsets.only(left:4.0,right:4.0,top:4.0,bottom:2.0),
      decoration: BoxDecoration(
        color:backgroundColor,//工厂里自定义的背景
        borderRadius: BorderRadius.circular(8.0)
      ),
      child: Text(
        title,//工厂里自定义的文字
        style: TextStyle(
          fontSize:10.0,
          color:color//工厂里自定义的字体颜色
        ),
      ),
    );
  }
}

搜索组件封装开发

步骤：

创建文件 /widgets/search_bar/index.dart
引入 material 依赖，创建有状态组件，添加参数
编写界面代码
测试

import 'package:flutter/material.dart';
import 'package:goodhouse/widgets/common_image.dart';

class SearchBar extends StatefulWidget {
  final bool showLocation; //是否显示位置
  final Function goBackCallback; //回退
  final String inputValue; //搜索框值
  final String defaultInputValue; //默认显示值
  final Function onCancel; //取消按钮
  final bool showMap; //是否显示地图按钮
  final Function onSearch; //点击搜索框触发
  final ValueChanged<String> onSearchSubmit; //点击按键回车触发

  const SearchBar(
      {Key key,
      this.showLocation,
      this.goBackCallback,
      this.inputValue = "",
      this.defaultInputValue = "请输入搜索词",
      this.onCancel,
      this.showMap,
      this.onSearch,
      this.onSearchSubmit})
      : super(key: key);

  @override
  _SearchBarState createState() => _SearchBarState();
}

class _SearchBarState extends State<SearchBar> {
  String _searchWord = '';
  TextEditingController _controller; //输入框的控制器
  FocusNode _focus; //焦点声明
  _onClean() {
    _controller.clear(); //清除输入框控制器
    setState(() {
      _searchWord = '';
    });
  }

  // 初始化控制器
  @override
  void initState() {
    _focus = FocusNode(); //初始化焦点
    _controller = TextEditingController(text: widget.inputValue);
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Container(
      child: Row(
        children: <Widget>[
          if (widget.showLocation != null)
            //location判断
            Padding(
              padding: EdgeInsets.only(right: 10.0),
              child: GestureDetector(
                //手势组件
                onTap: () {},
                child: Row(
                  children: <Widget>[
                    Icon(Icons.room, color: Colors.green, size: 16.0),
                    Text('北京',
                        style: TextStyle(color: Colors.black, fontSize: 14.0))
                  ],
                ),
              ),
            ),
          if (widget.goBackCallback != null)
            Padding(
                padding: EdgeInsets.only(right: 10.0),
                child: GestureDetector(
                    onTap: () {},
                    child: Row(children: <Widget>[
                      Icon(Icons.chevron_left, color: Colors.black87)
                    ]))),
          Expanded(
              //自适应组件
            child: Container(
            height: 34.0,
            decoration: BoxDecoration(
                borderRadius: BorderRadius.circular(17.0),
                color: Colors.grey[200]),
            margin: EdgeInsets.only(right: 10.0),
            child: TextField(
              // 优化start
              focusNode: _focus,
              onTap: (){
                if(widget.onSearchSubmit==null) {
                  _focus.unfocus();//解决回退失去焦点问题
                }
              widget.onSearch(); //使用自己定义的变量方法

              },
              onSubmitted: widget.onSearchSubmit,
              textInputAction: TextInputAction.search, //按键变为搜索
              controller: _controller, //自己定义的控制器
              onChanged: (String value) {
                //值改变问题
                setState(() {
                  _searchWord = value;
                });
              },
              // 优化end
              decoration: InputDecoration(
                  hintText: '请输入搜索词',
                  border: InputBorder.none,
                  contentPadding: EdgeInsets.only(top: -2.0, left: -10.0),
                  suffixIcon: GestureDetector(
                    //触摸控件
                    onTap: () {
                      _onClean();
                    },
                    child: Icon(
                      //后置图标
                      Icons.clear,
                      size: 18.0,
                      color: _searchWord == ''
                          ? Colors.grey[200]
                          : Colors.grey, //去图标的技巧:当空时设置为没颜色
                    ),
                  ),
                  icon: Padding(
                    padding: EdgeInsets.only(top: 4.0, left: 8.0),
                    child: Icon(
                      Icons.search,
                      size: 18.0,
                      color: Colors.grey,
                    ),
                  )),
            ),
          )),
          if (widget.onCancel != null)
            Padding(
                padding: EdgeInsets.only(right: 10.0),
                child: GestureDetector(
                    onTap: () {},
                    child: Row(children: <Widget>[
                      Text('取消',
                          style: TextStyle(color: Colors.black, fontSize: 14.0))
                    ]))),
          if (widget.showMap != null)
            CommonImage(src: 'static/icons/widget_search_bar_map.png')
        ],
      ),
    );
  }
}

主页搜索页使用封装好的搜索组件

  appBar:AppBar(
        title:SearchBar(showLocation: true,showMap: true,onSearch: (){
          // Navigator.of(context).pushNamed('search');//跳转到搜索页面
          print("跳转到搜索页面测试");
        },),
        backgroundColor: Colors.white,
      ),
```

我的页面

创建tab_profile/index.dart ```js import 'package:flutter/material.dart'; import 'package:goodhouse/pages/home/tab_profile/header.dart'; class TabProfile extends StatelessWidget { const TabProfile({Key key}) : super(key: key);

@override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( elevation:0,//去掉边框 title:Text('我的'), actions:[//右侧组件 IconButton( onPressed: (){ // Navigator.of(context).pushNamed(routeName); print("准备跳转到设置页"); }, icon:Icon(Icons.settings), ) ] ),

  body:ListView(
    children: <Widget>[
      Header(),
      Text('内容区域')
    ],
  )
);

} }

#### 准备头部header.dart
```js
import 'package:flutter/material.dart';

var loginFontStyle = TextStyle(fontSize: 20.0, color: Colors.white);

class Header extends StatelessWidget {
  const Header({Key key}) : super(key: key);
Widget _noLoginPageHeader(BuildContext context){
   return Container(
      decoration: BoxDecoration(color: Colors.green),
      height: 95.0,
      padding: EdgeInsets.only(top: 10.0, left: 20.0, bottom: 20.0),
      child: Row(children: <Widget>[
        Container(
          height: 65.0,
          width: 65.0,
          margin: EdgeInsets.only(right: 15.0),
          child: CircleAvatar(
            //圆形头像
            backgroundImage: NetworkImage(
                "https://tva1.sinaimg.cn/large/006y8mN6ly1g6tbgbqv2nj30i20i2wen.jpg"),
          ),
        ),
        Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: <Widget>[
            Padding(padding: EdgeInsets.only(top: 6.0)),
            Row(
              children: <Widget>[
                GestureDetector(
                  //手势组件
                  onTap: () {
                    Navigator.of(context).pushNamed("login");
                  },
                  child: Text('登录', style: loginFontStyle),
                ),
                Text("/", style: loginFontStyle),
                GestureDetector(
                  //手势组件
                  onTap: () {
                    print("点击了注册");
                    Navigator.of(context).pushNamed("rigister");
                  },
                  child: Text('注册', style: loginFontStyle),
                ),
              ],
            ),
            Text('登录后可以体验更多',style:TextStyle(color:Colors.white))
          ],
        )
      ]),
    );
}
Widget _loginPageHeader(BuildContext context){
  String userName="张三";
  String userImage="https://tva1.sinaimg.cn/large/006y8mN6ly1g6tbnovh8jj30hr0hrq3l.jpg";
   return Container(
      decoration: BoxDecoration(color: Colors.green),
      height: 95.0,
      padding: EdgeInsets.only(top: 10.0, left: 20.0, bottom: 20.0),
      child: Row(children: <Widget>[
        Container(
          height: 65.0,
          width: 65.0,
          margin: EdgeInsets.only(right: 15.0),
          child: CircleAvatar(
            //圆形头像
            backgroundImage: NetworkImage(userImage),
          ),
        ),
        Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: <Widget>[
            Padding(padding: EdgeInsets.only(top: 6.0)),
            Row(
              children: <Widget>[
               
                Text(userName, style: loginFontStyle),
               
              ],
            ),
            Text('查看编辑个人资料',style:TextStyle(color:Colors.white))
          ],
        )
      ]),
    );
}

  @override
  Widget build(BuildContext context) {
    var isLogin=false;
   return isLogin ?_noLoginPageHeader(context):_loginPageHeader(context);
  }
}

功能按钮

1.准备数据文件 pages/home/tab_profile/function_button_data.dart

import 'package:flutter/material.dart';

class FunctionButtonItem{
  final String imageUrl;
  final String title;
  final Function onTapHandle;
  FunctionButtonItem(this.imageUrl,this.title,this.onTapHandle);
}

final List<FunctionButtonItem> list=[
  FunctionButtonItem('static/images/home_profile_record.png', "看房记录", (){}),
  FunctionButtonItem('static/images/home_profile_order.png', '我的订单', null),
  FunctionButtonItem('static/images/home_profile_favor.png', '我的收藏', null),
  FunctionButtonItem('static/images/home_profile_id.png', '身份认证', null),
  FunctionButtonItem('static/images/home_profile_message.png', '联系我们', null),
  FunctionButtonItem('static/images/home_profile_contract.png', '电子合同', null),
  FunctionButtonItem('static/images/home_profile_wallet.png', '钱包', null),
  FunctionButtonItem('static/images/home_profile_house.png', "房屋管理", (context){
    bool isLogin=true;//假设先设置未登录
    if(isLogin){
      Navigator.pushNamed(context, 'login');
    }
  })
  
];

创建function_button.dart组件

import 'package:flutter/material.dart';

import 'function_button_data.dart';
class FunctionButton extends StatelessWidget {
  const FunctionButton({Key key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Container(
      child: Wrap(
        spacing: 1.0,
        runSpacing: 1.0,
        children:list.map((item)=>Container(
          height:20.0,
          width:MediaQuery.of(context).size.width*0.33,
          decoration: BoxDecoration(color:Colors.red),
        )).toList(),
      )
    );
  }
}

item选项组件封装

import 'package:flutter/material.dart';

import '../../../widgets/common_image.dart';
import 'function_button_data.dart';

class FunctionButtonWidget extends StatelessWidget {
  final FunctionButtonItem data;
  const FunctionButtonWidget(this.data,{Key key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap:(){
        if(data.onTapHandle!=null){
          data.onTapHandle(context);
        }
      },
      child:Container(
        margin: EdgeInsets.only(top:30.0),
        width: MediaQuery.of(context).size.width*0.33,
        child: Column(
          children:<Widget>[
            CommonImage(src:data.imageUrl),
            Text(data.title)
          ]
        ),
      )
    );
  }
}

广告组件Advertisement.dart

import 'package:flutter/material.dart';

import '../../../widgets/common_image.dart';
class Advertisement extends StatelessWidget {
  const Advertisement({Key key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Container(
      padding: EdgeInsets.only(top:30.0,bottom:20.0,left:10.0,right:10.0),
      child: CommonImage(src:'https://tva1.sinaimg.cn/large/006y8mN6ly1g6te62n8f4j30j603vgou.jpg')
    );
  }
}

右上角设置页

效果：

分析：

需要 toast 弹窗，使用 fluttertoast

用法：

// 1. 安装依赖
fluttertoast: ^4.0.0

// 2. 引入依赖
import 'package:fluttertoast/fluttertoast.dart';

// 3. 使用
Fluttertoast.showToast(
      msg: "This is Center Short Toast",
      toastLength: Toast.LENGTH_SHORT,
      gravity: ToastGravity.CENTER,
      timeInSecForIos: 1,
      backgroundColor: Colors.red,
      textColor: Colors.white,
      fontSize: 16.0
  );

步骤：

准备
1. 按照依赖 fluttertoast: ^3.1.3
2. utils/common_toast.dart 新建文件，封装 CommonToast
3. 新建文件 pages/setting.dart，引入依赖，添加无状态组件
核心编码
1. 完成页面主体结构
2. 在路由系统注册当前页面
3. 添加退出登陆按钮
4. 实现退出登陆逻辑
房屋管理页面开始

参考flutter官网的appBar:https://flutterchina.club/catalog/samples/tabbed-app-bar/
```
import 'package:flutter/material.dart';
```

import 'package:goodhouse/pages/home/tab_search/dataList.dart'; import 'package:goodhouse/widgets/room_list_item_widget.dart';

class RoomManagePage extends StatelessWidget { const RoomManagePage({Key key}) : super(key: key); @override Widget build(BuildContext context) { return DefaultTabController( length: 2,//tab个数 initialIndex: 0,//初始索引 child: Scaffold( appBar: AppBar( title: Text('房屋管理'), bottom: TabBar( tabs: [ Tab(text:'空置'), Tab(text:'已租'), ] ), ), body: TabBarView( children: [ ListView( children:dataList.map((item)=> RoomListItemWidget(item) ).toList() ), ListView( children:dataList.map((item)=> RoomListItemWidget(item) ).toList() ) ] ), ), );

} }

同时增加底部悬浮按钮
准备悬浮按钮common_floating_button.dart组件
```js
import 'package:flutter/material.dart';
class CommonFloatingButton extends StatelessWidget {
  final String title;
  final Function onTap;

  const CommonFloatingButton(this.title, this.onTap,{Key key}) : super(key: key);
  

  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap:(){
        if(onTap!=null) onTap();
      },
      child:Container(
        margin: EdgeInsets.all(20.0),
        height: 40.0,
        decoration: BoxDecoration(
          borderRadius:BorderRadius.circular(10.0),
          color:Colors.green
        ),
        child: Center(
          child:Text(title,style:TextStyle(
            color:Colors.white,
            fontSize:16.0,
            fontWeight:FontWeight.w600
          ))
        ),
      )
    );
  }
}

在Scaffold组件中加入悬浮按钮

floatingActionButtonLocation: FloatingActionButtonLocation.centerFloat,//悬浮位置
          floatingActionButton: CommonFloatingButton('发布房源', (){
            Navigator.of(context).pushNamed("login");
          }),

发布房源页面开发

里面对各个组件进行了封装大体代码如下

import 'package:flutter/material.dart';
import 'package:goodhouse/widgets/common_floating_button.dart';
import 'package:goodhouse/widgets/common_form_item.dart';
import 'package:goodhouse/widgets/common_image_pick.dart';
import 'package:goodhouse/widgets/common_radio_form_item.dart';
import 'package:goodhouse/widgets/common_select_form_item.dart';
import 'package:goodhouse/widgets/common_title.dart';
import 'package:goodhouse/widgets/room_Appliance.dart';

class RoomAddPage extends StatefulWidget {
  RoomAddPage({Key key}) : super(key: key);

  @override
  _RoomAddPageState createState() => _RoomAddPageState();
}

class _RoomAddPageState extends State<RoomAddPage> {
  int rentType=0;
  int rentTypeTwo=0;
  int roomType = 0;
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar:AppBar(
        title:Text('发布房源'),
      ),
      floatingActionButton: CommonFloatingButton('提交', (){
        print("点击了提交");
      }),
      floatingActionButtonLocation: FloatingActionButtonLocation.centerFloat,
      body:ListView(
        children:<Widget>[
          CommonTitle('房源信息'),
          CommonFormItemWidget(//自定义小区
            label: '小区',
            contentBuilder:(context){
              return Container(
                height: 40.0,
                width: 280.0,
                child:GestureDetector(
                  behavior: HitTestBehavior.translucent,//解决点击空白地方无效问题
                  child: Row(
                    mainAxisAlignment: MainAxisAlignment.spaceBetween,
                    children: <Widget>[
                      Text('请选择小区',style:TextStyle(
                        fontSize:16.0
                      )),
                      Icon(Icons.keyboard_arrow_right)
                    ],
                  ),
                  onTap: (){
                    print("跳转选择小区页");
                  },
                )
              );
            }
          ),
          CommonFormItemWidget(
            label: '租金',
            hitText:'请输入租金',
            suffixText: '元/月',
            controller: TextEditingController(),
          ),
          CommonFormItemWidget(
            label: '大小',
            hitText:'请输入房屋大小',
            suffixText: '平方米',
            controller: TextEditingController(),
          ),
          CommonRadioFormIten(
            label: '租赁方式',

因真实接口失效了,故只用了一个真实线上模拟接口.

增加启动页面

配置启动页面路由和设置第一页为启动页. 启动页面核心代码

import 'dart:async';

import 'package:flutter/material.dart';

class LoadingPage extends StatefulWidget {
  LoadingPage({Key key}) : super(key: key);

  @override
  _LoadingPageState createState() => _LoadingPageState();
}

class _LoadingPageState extends State<LoadingPage> {
  @override
  void initState() {
    Timer(Duration(seconds: 3), () {
      Navigator.of(context).pushReplacementNamed('/');
    });
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Container(
      decoration: BoxDecoration(
          image: DecorationImage(
              fit: BoxFit.fill,
              image: AssetImage('static/images/loading.jpg'))),
    );
  }
}

安卓打包

步骤：

修改应用名称 /项目目录/android/app/src/main/AndroidManifest.xml 文件 application 标签 android:label 属性
修改图标及背景图(背景图解决空白问题,我是直接替换res文件夹的) 文件地址：/resource/chapter6/01静态资源/package/android/res 目标地址：/项目目录/android/app/src/main/res
修改构建配置(构建时不需要检验) 在 android/app/build.gradle 文件中 android.lintOption 添加属性 checkReleaseBuilds false
构建 flutter build apk

打包成功后apk文件的位置:build\app\outputs\apk\release\app-release.apk (18.4MB) 安装成功后,打开有闪退问题,在 android/app/build.gradle 文件,最后解决办法:

    buildTypes {
        release {
            signingConfig signingConfigs.debug
            //关键代码:关闭混淆,解决闪退问题
            minifyEnabled false
            shrinkResources false
            // 关键代码:解决闪退问题
        }
    }

我安装后测试能正常运行,本次开发告一段落,但学习不会停止,请期待下一个开发.
