如何使flutter dart中的流与provider一起工作

dependencies:
  flutter:
    sdk: flutter
  provider: ^5.0.0

StreamController<String> _streamController = StreamController<String>();
Stream<String> get stream => _streamController.stream;

return Provider<Stream<String>>.value(
  value: _streamController.stream,
  child: YourWidget(),
);

Stream<String> stream = Provider.of<Stream<String>>(context);

StreamBuilder<String>(
  stream: stream,
  builder: (context, snapshot) {
    if (snapshot.hasData) {
      // 处理流的数据
      return Text(snapshot.data);
    } else {
      // 流没有数据时的处理
      return CircularProgressIndicator();
    }
  },
)
