android - Flutter 小部件未在通知单击时呈现

Question

我正在使用firebase_messaging和flutter_local_notifications库来通知一切工作正常。但是在 Android 中，如果从应用程序堆栈中删除应用程序（从最近的 Activity 中删除幻灯片）而不是收到通知并单击它，则小部件无法正确呈现，按钮导航、应用程序栏、文本正在消失。

 @override
 Widget build(BuildContext context) {

return LayoutBuilder(builder: (_, constraints) {
  return OrientationBuilder(builder: (_, orientation) {
    SizeConfig().init(constraints, orientation);
    return MultiBlocProvider(
        providers: [
          BlocProvider(create: (_)=>_mainAppBarBloc),
          BlocProvider(create: (_) => _hadyahBloc),
   
        ],
        child:MultiBlocListener(
            listeners: [
              BlocListener<HadyahBloc,HadyahState>(
                listener: (_,state){
                  state.whenPartial(
                    getLanguage: (s){
                      var locale = _hadyahBloc.changeLanguage(s.language);
                      setLocale(locale);
                    },
                  );
                },
              ),
