Currently, there is no official package 🙏.
But you can use my RxStreamBuilder class in flutter_bloc_pattern package

final stateStream = BehaviorSubject.seeded(1);
RxStreamBuilder<State>(
  stream: stateStream,
  builder: (context, State state) {
    // use state directly
  }
)

Great, although it would be nice if there was something official and agnostic to the bloc pattern, cause it is also used a lot in Flutter.

For example, a complementary .watch and .listen for flutter just like signals do.

Thanks

@MiniSuperDev I will consider adding an official package
