如何在flutter中传递主本地或主外部屏幕的配置文件屏幕中的数据？

class SecondScreen extends StatelessWidget {
  final String data;

  SecondScreen({required this.data});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Second Screen'),
      ),
      body: Center(
        child: Text(data),
      ),
    );
  }
}

Navigator.push(
  context,
  MaterialPageRoute(builder: (context) => SecondScreen(data: 'Hello World')),
);

dependencies:
  provider: ^6.0.1

class DataModel with ChangeNotifier {
  String _data = '';
  String get data => _data;

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

void main() {
  runApp(
    ChangeNotifierProvider(
      create: (context) => DataModel(),
      child: MyApp(),
    ),
  );
}

class SecondScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final dataModel = Provider.of<DataModel>(context);

    return Scaffold(
      appBar: AppBar(
        title: Text('Second Screen'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text(dataModel.data),
            ElevatedButton(
              onPressed: () {
                dataModel.setData('New Data');
              },
              child: Text('Change Data'),
            ),
          ],
        ),
      ),
    );
  }
}

class GlobalData {
  static final GlobalData _instance = GlobalData._internal();
  factory GlobalData() => _instance;
  GlobalData._internal();

  String data = '';
}

GlobalData().data = 'New Data';
print(GlobalData().data);
