CombineLatestStream is the solution.

CombineLatestStream<QuerySnapshot, List<QuerySnapshot>> roomStream() {
    try {
      Stream<QuerySnapshot> s1 = users.where("uid",isNotEqualTo: firebaseAuth.currentUser.uid).snapshots();
      Stream<QuerySnapshot> s2 = groupService.streamGroup();
      return CombineLatestStream.list<QuerySnapshot>([s1,s2]);
    } catch (e) {
      handleException(e);
      throw e;
    }
  }

Thanks pskink
