TimelineUtil.format 总是要快8个小时 , 设置了 locale:'zh'， 也不行

      var t = DateTime.parse('2020-07-22 22:45:00');
      var ts = TimelineUtil.format(
        t.millisecondsSinceEpoch,

        dayFormat: DayFormat.Full,
      );

      print(ts);

The library 'package:flustars/flustars.dart' is legacy, and should not be imported into a null safe library.

初始化代码

void main() {
_initApp();
runApp(const MyApp());
}

_initApp() async {

我用ScreenUtil获取的宽高不准确，具体代码如下：

获取了appBar的高度作为shouMenu的top，但是实际位置不对：

ScreenUtil没做其他任何初始化。是我用的有问题吗？还是有什么其他问题呢？求解答下，多谢了

错误内容如上，在执行了brew install cocoapods && pod setup 也是不行的。

但是在iPhone模式下可以，很奇怪啊。

通过实验，在terminal中通过flutter run进行运行是可以的，然后关闭这个，再次通过ide的build工具运行，虽然还是出现让 brew install cocoapods && pod setup 这个错误，但是可以进行运行起来了。

经测，在小米K40 Pro+手机（MIUI 13.0.5， Android 12）上，如使用Release模式运行：flutter run --release

screenWidth， screenHeight, statusBarHeight, bottomBarHeight, appBarHeight等基础属性全为0，间接导致几乎所有方法均返回为0，如getSp

如： String apkPath = DirectoryUtil.getStoragePath(category:'Download',fileName: 'app_release',format: 'apk');
打印apkPath 一直返回是null?

我想在APP启动的时候读取上次登录已经存在本地的userId和userName，但是获取这两个字段一直获取不到。

在mac下可以，在win下出以上提示

你好，我是flutter新手，查本地存储的时候查到的这个库。发现里面关于异步读取本地存储的代码：
Future.delayed(new Duration(milliseconds: 500), () { /// 同步使用Sp。 /// 是否显示引导页。 if (SpUtil.getBool("key_guide", defValue: true)) { SpUtil.putBool("key_guide", false); _initBanner(); } else { _initSplash(); } });

延迟500毫秒就可以确定是同步读取吗？谢谢

GlobalObjectKey conTextKey = GlobalObjectKey('contenxt');

RenderBox box = conTextKey.currentContext.findRenderObject();
box.localToGlobal(Offset.zero)

这样能获取某个控制在页面,的具体位置,一般页面滚动到某个位置后,要去回到某个控制的位置上去,就得这么干,
不同于直接滚动到0,这是要滚动到不确定的位置

请教个问题，Android原生可以通过设置sp库名称（FlutterSharedPreferences）来获取flutter存储的数据，而在flutter里面要通过什么方式来获取原生sp存储的数据呢。

用SpUtil存值后，重新打开app后获取不到之前保存的值。

String _src="https://dsd361-oss1.oss-cn-beijing.aliyuncs.com/upload/advert/2d56ad78-472d-4eaf-b1f1-9a6887089d17.gif";

Rect rect2 = await WidgetUtil.getImageWH(url: _src);

Error: Method not found: 'ImageStreamListener'. 一直报这个错误！这是怎么回事？

如果用swift如果配置log啊

[VERBOSE-2:ui_dart_state.cc(166)] Unhandled Exception: MissingPluginException(No implementation found for method logD on channel x_log)
#0 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:154:7)

if (SpUtil.getBool('key_test', defValue: true)) {
       SpUtil.putBool('key_test', false); //虽然设置成false ,但是下次还会执行进来
  }

看了下源码

 static bool getBool(String key, {bool defValue = false}) {
    if (_prefs == null) return defValue; 
    return _prefs.getBool(key) ?? defValue;  
  }

可能需要做以下修改

 static bool getBool(String key, {bool defValue = false}) {
    if (_prefs == null || _prefs.getBool(key) == null) return defValue; 
    return _prefs.getBool(key);
  }

获取不到ListView的高度

iOS工程里引入了flutter module模块，flutter module里用到了flustars: ^0.2.6+1 插件，xcode项目编译与运行正常，当xcode执行archive的时候编译报错，报错提示在path_provider库，报错内容如下：

我看您的这个插件中有引用到path_provider这个插件库，是不是什么原因导致的这个报错呢

有一个接口使用DioUtil需要设置header,其他接口不需要，怎么设置header头的，在案例里面只有设置公共的，请求的怎么设置

在flutter 界面后设置 key value 后 ，在跳转原生界面后 无法通过SharedPreferences 原生api 获取。

请问这个类库里，有没有比较好用的保存图片的支持？

Because flutter_cache_manager 0.2.0+1 depends on shared_preferences ^0.4.0 and no versions of flutter_cache_manager match >0.2.0+1 <0.3.0, flutter_cache_manager ^0.2.0+1 requires shared_preferences ^0.4.0.
And because flustars >=0.2.1 depends on shared_preferences ^0.5.0, flustars >=0.2.1 is incompatible with flutter_cache_manager ^0.2.0+1.
And because cached_network_image 0.5.1 depends on flutter_cache_manager ^0.2.0+1 and no versions of cached_network_image match >0.5.1 <0.6.0, flustars >=0.2.1 is incompatible with cached_network_image ^0.5.1.
So, because module_flutter depends on both cached_network_image ^0.5.1 and flustars 0.2.2, version solving failed.

降级为0.2.0版本啦
