如何将根文件(main.dart)中的数据传递到不同的页面，如flutter中的android broadcast receiver

import 'package:flutter/material.dart';
import 'package:provider/provider.dart';

class DataModel extends ChangeNotifier {
  String data = '';

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      home: HomePage(),
    );
  }
}

import 'package:flutter/material.dart';
import 'package:provider/provider.dart';

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Home Page'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text(
              'Data: ${Provider.of<DataModel>(context).data}',
              style: TextStyle(fontSize: 24),
            ),
            RaisedButton(
              child: Text('Update Data'),
              onPressed: () {
                Provider.of<DataModel>(context, listen: false)
                    .updateData('New Data');
              },
            ),
            RaisedButton(
              child: Text('Go to Another Page'),
              onPressed: () {
                Navigator.push(
                  context,
                  MaterialPageRoute(builder: (context) => AnotherPage()),
                );
              },
            ),
          ],
        ),
      ),
    );
  }
}

class AnotherPage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Another Page'),
      ),
      body: Center(
        child: Text(
          'Data: ${Provider.of<DataModel>(context).data}',
          style: TextStyle(fontSize: 24),
        ),
      ),
    );
  }
}
