我正在尝试在有状态小部件中包含一个blocprovider CounterCubit。这是正确的方法吗？我已经创建了一个StatelessWidget Uno，其中一个blocprovider将有状态小部件UnoMain作为子级。

class Uno extends StatelessWidget {
  const Uno({super.key});

  @override
  Widget build(BuildContext context) {
    return BlocProvider(
      create: (_) => CounterCubit(),
      child: UnoMain(),
    );
  }
}

class UnoMain extends StatefulWidget {
  const UnoMain({ super.key });

  @override
  State<UnoMain> createState() => _UnoMainState();
}

class _UnoMainState extends State<UnoMain> {

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Material App Bar'),
      ),
      body: BlocBuilder<CounterCubit, int>(
        builder: (context, count) => Center(
            child: Column(
          children: [
            ...
          ],
        )),
      ),
      floatingActionButton: Column(
        ...
      ),
    );
  }
}
