如何在blocs构建器中将相同的小部件传递给所有状态

class MyWidget extends InheritedWidget {
  final Widget child;
  final String sharedData;

  MyWidget({Key key, @required this.child, @required this.sharedData})
      : super(key: key);

  static MyWidget of(BuildContext context) {
    return context.dependOnInheritedWidgetOfExactType<MyWidget>();
  }

  @override
  bool updateShouldNotify(MyWidget oldWidget) {
    return sharedData != oldWidget.sharedData;
  }
}

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MyWidget(
      sharedData: 'Shared Data',
      child: MaterialApp(
        title: 'My App',
        home: HomeScreen(),
      ),
    );
  }
}

class HomeScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final sharedData = MyWidget.of(context).sharedData;

    return Scaffold(
      appBar: AppBar(
        title: Text('Home'),
      ),
      body: Center(
        child: Text(sharedData),
      ),
    );
  }
}
