    dynamic streamInfo, dynamic state, dynamic reason) async {
  if ($instance == null || $instance is! IRTCRoomEventHandler) {
    return;
  }
  return ($instance as IRTCRoomEventHandler)
      .onVideoSubscribeStateChanged
      ?.call(
          streamId.toString(),
          t_SubscribeState.android_to_code($p_a.SubscribeState.values
              .firstWhere((t) => t.$value == state || t.name == state)),
          t_SubscribeStateChangeReason.android_to_code($p_a
              .SubscribeStateChangeReason.values
              .firstWhere((t) => t.$value == reason || t.name == reason)));
