onWTNVideoSubscribeStateChanged$state$reason method

FutureOr<void> onWTNVideoSubscribeStateChanged$state$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 视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 视频流订阅状态变化回调
通过 subscribeWTNVideoStream:subscribe:{@link #ByteRTCWTNStream#subscribeWTNVideoStream:subscribe} 订阅 WTN 视频流后，可以通过本回调获取订阅结果。 @param streamId WTN 视频流的 ID @param state 视频流状态码，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

  }
  return ($instance as IWTNStreamEventHandler)
      .onWTNVideoSubscribeStateChanged
      ?.call(

          t_WTNSubscribeState.ios_to_code($p_i.ByteRTCWTNSubscribeState.values
              .firstWhere((t) => t.$value == state || t.name == state)),
