Create provider that returns a stream based on a stream

[melanki]

Hi,

I have stream A, and want to get and return object from stream B based on A.property.
What is the best way to approach this?

final streamProvider =
    StreamProvider.<bool?>((ref) async* {
      A objectA = await ref.watch(objectAstreamProvider.last);
  yield* B.getObject(
      property: objectA.property;
});
