如何在flutter中创建同一provider的多个实例

dependencies:
  flutter:
    sdk: flutter
  provider: ^5.0.0

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

class Counter {
  int count = 0;

  void increment() {
    count++;
  }
}

void main() {
  runApp(
    MultiProvider(
      providers: [
        ChangeNotifierProvider(create: (_) => Counter()),
        ChangeNotifierProvider(create: (_) => Counter()),
      ],
      child: MyApp(),
    ),
  );
}

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

class MyHomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final counter1 = Provider.of<Counter>(context);
    final counter2 = Provider.of<Counter>(context, listen: false);

    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Provider Demo'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Text('Counter 1: ${counter1.count}'),
            Text('Counter 2: ${counter2.count}'),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: () {
          counter1.increment();
          counter2.increment();
        },
        child: Icon(Icons.add),
      ),
    );
  }
}
