如果我们在BlocProvider中有3个BLoCBuilders，我们可以在同一个类中使用2个BLoCs吗？

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

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return BlocProvider(
      create: (context) => FirstBloc(),
      child: BlocProvider(
        create: (context) => SecondBloc(),
        child: Scaffold(
          appBar: AppBar(
            title: Text('My Widget'),
          ),
          body: Column(
            children: [
              BlocBuilder<FirstBloc, FirstState>(
                builder: (context, state) {
                  // 使用第一个BLoC的状态和方法
                  return Text('First BLoC: ${state.data}');
                },
              ),
              BlocBuilder<SecondBloc, SecondState>(
                builder: (context, state) {
                  // 使用第二个BLoC的状态和方法
                  return Text('Second BLoC: ${state.data}');
                },
              ),
            ],
          ),
        ),
      ),
    );
  }
}

class FirstBloc extends Bloc<FirstEvent, FirstState> {
  // 实现第一个BLoC的逻辑
}

class SecondBloc extends Bloc<SecondEvent, SecondState> {
  // 实现第二个BLoC的逻辑
}

class FirstEvent {}

class FirstState {}

class SecondEvent {}

class SecondState {}
