如何在Flutter中检测抽屉中的数据变化？

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

// 定义数据模型
class DrawerDataModel extends ChangeNotifier {
  String _data = 'Initial Data';

  String get data => _data;

  set data(String newData) {
    _data = newData;
    notifyListeners(); // 通知监听器数据发生变化
  }
}

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter Drawer Data Change Detection'),
        ),
        drawer: MyDrawer(),
        body: Center(
          child: Consumer<DrawerDataModel>(
            builder: (context, dataModel, _) {
              return Text(dataModel.data);
            },
          ),
        ),
      ),
    );
  }
}

class MyDrawer extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Drawer(
      child: ListView(
        children: [
          ListTile(
            title: Text('Change Data'),
            onTap: () {
              // 修改数据
              Provider.of<DrawerDataModel>(context, listen: false).data =
                  'New Data';
              Navigator.pop(context); // 关闭抽屉
            },
          ),
        ],
      ),
    );
  }
}
