如何在flutter中将控制器数据从一个小部件传递到另一个小部件

class SourceWidget extends StatelessWidget {
  final String data;

  SourceWidget({required this.data});

  @override
  Widget build(BuildContext context) {
    return TargetWidget(data: data);
  }
}

class TargetWidget extends StatelessWidget {
  final String data;

  TargetWidget({required this.data});

  @override
  Widget build(BuildContext context) {
    return Text(data);
  }
}

class DataWidget extends InheritedWidget {
  final String data;

  DataWidget({required this.data, required Widget child}) : super(child: child);

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

  @override
  bool updateShouldNotify(DataWidget oldWidget) {
    return data != oldWidget.data;
  }
}

class SourceWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return DataWidget(
      data: 'Hello',
      child: TargetWidget(),
    );
  }
}

class TargetWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final dataWidget = DataWidget.of(context);
    final data = dataWidget?.data ?? '';

    return Text(data);
  }
}

class DataProvider extends ChangeNotifier {
  String _data = '';

  String get data => _data;

  void updateData(String newData) {
    _data = newData;
    notifyListeners();
  }
}

class SourceWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ChangeNotifierProvider<DataProvider>(
      create: (_) => DataProvider(),
      child: TargetWidget(),
    );
  }
}

class TargetWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final dataProvider = Provider.of<DataProvider>(context);
    final data = dataProvider.data;

    return Text(data);
  }
}
