  Future<void> initialize() async {

  }

  Widget _viewRows() {
    final List<StatefulWidget> list = [];
    if (widget.role == ClientRole.Broadcaster) {
      list.add(const rtcLocalView.SurfaceView());

    for (var uid in _users) {

    }
    final views = list;
    return Column(
      children: List.generate(
        views.length,
        (index) => Expanded(
          child: views[index],
        ),
      ),
    );
  }
