android接入flutter 需要引入Flutter Boos
1.接入形势aar包 命令:flutter build aar
android { // ... }
repositories { maven { //本地地址 url 'some/path/my_flutter/build/host/outputs/repo' // This is relative to the location of the build.gradle file // if using a relative path. } maven { //命令后的地址直接复制粘贴 url 'https://storage.googleapis.com/download.flutter.io' } }
dependencies { // 自己包的名字 可直接 implementation debugImplementation 'com.example.flutter_module:flutter_debug:1.0' profileImplementation 'com.example.flutter_module:flutter_profile:1.0' releaseImplementation 'com.example.flutter_module:flutter_release:1.0' }
2.在AndroidManifest文件加入
</activity>
<!--版本号-->
<meta-data android:name="flutterEmbedding"
android:value="2">
</meta-data>
3.在MyApplication加入 INativeRouter router =new INativeRouter() { @Override public void openContainer(Context context, String url, Map<String, Object> urlParams, int requestCode, Map<String, Object> exts) { String assembleUrl=Utils.assembleUrl(url,urlParams); PageRouter.openPageByUrl(context,assembleUrl, urlParams); }
};
FlutterBoost.BoostLifecycleListener boostLifecycleListener= new FlutterBoost.BoostLifecycleListener(){
@Override
public void beforeCreateEngine() {
}
@Override
public void onEngineCreated() {
}
@Override
public void onPluginsRegistered() {
}
@Override
public void onEngineDestroy() {
}
};
//
// AndroidManifest.xml 中必须要添加 flutterEmbedding 版本设置
//
// <meta-data android:name="flutterEmbedding"
// android:value="2">
// </meta-data>
// GeneratedPluginRegistrant 会自动生成 新的插件方式
//
// 插件注册方式请使用
// FlutterBoost.instance().engineProvider().getPlugins().add(new FlutterPlugin());
// GeneratedPluginRegistrant.registerWith()，是在engine 创建后马上执行，放射形式调用
//
Platform platform= new FlutterBoost
.ConfigBuilder(this,router)
.isDebug(true)
.whenEngineStart(FlutterBoost.ConfigBuilder.ANY_ACTIVITY_CREATED)
.renderMode(FlutterView.RenderMode.texture)
.lifecycleListener(boostLifecycleListener)
.build();
FlutterBoost.instance().init(platform);
4.加android代码跳转flutter路由
public class PageRouter {
public final static Map<String, String> pageName = new HashMap<String, String>() {{
put("first", "first");
put("second", "second");
put("tab", "tab");
put("sample://flutterPage", "flutterPage");
}};
public static final String NATIVE_PAGE_URL = "sample://nativePage";
public static final String FLUTTER_PAGE_URL = "sample://flutterPage";
public static final String FLUTTER_FRAGMENT_PAGE_URL = "sample://flutterFragmentPage";
public static boolean openPageByUrl(Context context, String url, Map params) {
return openPageByUrl(context, url, params, 0);
}
public static boolean openPageByUrl(Context context, String url, Map params, int requestCode) {
String path = url.split("\\?")[0];
Log.i("openPageByUrl",path);
try {
if (pageName.containsKey(path)) {
Intent intent = BoostFlutterActivity.withNewEngine().url(pageName.get(path)).params(params)
.backgroundMode(BoostFlutterActivity.BackgroundMode.opaque).build(context);
if(context instanceof Activity){
Activity activity=(Activity)context;
activity.startActivityForResult(intent,requestCode);
}else{
context.startActivity(intent);
}
return true;
} else if (url.startsWith(FLUTTER_FRAGMENT_PAGE_URL)) {
context.startActivity(new Intent(context, FlutterFragmentPageActivity.class));
return true;
} else if (url.startsWith(NATIVE_PAGE_URL)) {
context.startActivity(new Intent(context, NativePageActivity.class));
return true;
}
return false;
} catch (Throwable t) {
return false;
}
}
}
5.传递参数到flutter Map params = new HashMap(); params.put("test1","v_test1"); params.put("test2","v_test2"); 6.创建flutter fragment new FlutterFragment.NewEngineFragmentBuilder().url("flutterFragment").build();
7.主要flutter main里写 import 'package:flutter/material.dart'; import 'package:flutter_boost/flutter_boost.dart'; import 'simple_page_widgets.dart';
void main() { runApp(MyApp()); }
class MyApp extends StatefulWidget { @override _MyAppState createState() => _MyAppState(); }
class _MyAppState extends State { @override void initState() { super.initState();
FlutterBoost.singleton.registerPageBuilders({
'embeded': (pageName, params, _)=>EmbededFirstRouteWidget(),
'first': (pageName, params, _) => FirstRouteWidget(),
'firstFirst': (pageName, params, _) => FirstFirstRouteWidget(),
'second': (pageName, params, _) => SecondRouteWidget(),
'secondStateful': (pageName, params, _) => SecondStatefulRouteWidget(),
'tab': (pageName, params, _) => TabRouteWidget(),
'platformView': (pageName, params, _) => PlatformRouteWidget(),
'flutterFragment': (pageName, params, _) => FragmentRouteWidget(params),
///可以在native层通过 getContainerParams 来传递参数
'flutterPage': (pageName, params, _) {
print("flutterPage params:$params");
return FlutterRouteWidget(params:params);
},
});
FlutterBoost.singleton.addBoostNavigatorObserver(TestBoostNavigatorObserver());
}
@override Widget build(BuildContext context) { return MaterialApp( title: 'Flutter Boost example', builder: FlutterBoost.init(postPush: _onRoutePushed), home: Container( color:Colors.white )); }
void _onRoutePushed( String pageName, String uniqueId, Map params, Route route, Future _) { } } class TestBoostNavigatorObserver extends NavigatorObserver{ void didPush(Route route, Route previousRoute) {
print("flutterboost#didPush");
}
void didPop(Route route, Route previousRoute) { print("flutterboost#didPop"); }
void didRemove(Route route, Route previousRoute) { print("flutterboost#didRemove"); }
void didReplace({Route newRoute, Route oldRoute}) { print("flutterboost#didReplace"); } }
