addTeamSubscribe method

Implementation

void addTeamSubscribe() {
  _teamSub = TeamRepo.registerTeamUpdateObserver().listen((event) {
    for (var e in event) {
      if (e.id == teamWithMember?.team.id) {
        // 这里iOS需要在回调之后请求，否则查询结果不对
        if (teamWithMember?.team.memberCount != e.memberCount) {
          requestTeamMembers(e.id!);
        }
        teamWithMember?.team = e;
        notifyListeners();
      }
    }
  });
}
