如何在flutter中拥有相同数据类型的多个流提供者？

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

class DataProvider {
  int data = 0;
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MultiProvider(
      providers: [
        StreamProvider<int>.value(
          value: Provider.of<DataProvider>(context).dataStream1,
        ),
        StreamProvider<int>.value(
          value: Provider.of<DataProvider>(context).dataStream2,
        ),
      ],
      child: MaterialApp(
        home: HomeScreen(),
      ),
    );
  }
}

class HomeScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Multi Stream Provider Example'),
      ),
      body: Center(
