derivedStream? #58

Closed lukepighetti closed 7 months ago

lukepighetti commented 7 months ago

Common pattern in state management to depend on a reactive value and use it to manage/switch streams

ie: 

final userProfileSignal = derivedStreamSignal<UserProfile>((){
  final uid = myUidSignal();
  return myUserProfileStream(uid);
});

and then have it automatically handle setup and teardown of the profile stream as the user id changes

Is does state_beacon have this feature, and if not, please consider this a feature request

That's an interesting concept, I think the current derived beacon could be modified to treat streams differently..
