onWTNAudioSubscribeStateChanged$state$reason method

FutureOr<void> onWTNAudioSubscribeStateChanged$state$reason(dynamic streamId, dynamic state, dynamic reason)

@detail callback @valid since 3.60. 自 3.60 起，该回调替代了 rtcEngine:onPlayPublicStreamResult:errorCode: 方法中的 WTN 音频流订阅状态变化通知功能。如果你已升级至 3.60 及以上版本，并且仍在使用该方法，请迁移到此回调。 @author hanchenchen @brief WTN 音频流订阅状态变化回调
通过 subscribeWTNAudioStream:subscribe:{@link #ByteRTCWTNStream#subscribeWTNAudioStream:subscribe} 订阅 WTN 音频流后，可以通过本回调获取订阅结果。 @param streamId WTN 音频流的 ID @param state 音频流状态码，参看 ByteRTCWTNSubscribeState{@link #ByteRTCWTNSubscribeState}。 @param reason 订阅状态发生变化的原因，参看 ByteRTCWTNSubscribeStateChangeReason{@link #ByteRTCWTNSubscribeStateChangeReason}。 @order 2

Implementation

    dynamic streamId, dynamic state, dynamic reason) async {
  if ($instance == null || $instance is! IWTNStreamEventHandler) {
    return;
  }
  return ($instance as IWTNStreamEventHandler)
      .onWTNAudioSubscribeStateChanged
      ?.call(
          streamId.toString(),
          t_WTNSubscribeState.ios_to_code($p_i.ByteRTCWTNSubscribeState.values
              .firstWhere((t) => t.$value == state || t.name == state)),
          t_WTNSubscribeStateChangeReason.ios_to_code($p_i
              .ByteRTCWTNSubscribeStateChangeReason.values
              .firstWhere((t) => t.$value == reason || t.name == reason)));
