setAudioRoute method

Future<int?> setAudioRoute(AudioRoute audioRoute)

@detail api @author dixing @brief Set the current audio playback route. The default device is set via setDefaultAudioRoute{@link #RTCEngine#setDefaultAudioRoute}.
When the audio playback route changes, you will receive onAudioRouteChanged{@link #IRTCEngineEventHandler#onAudioRouteChanged}. @param audioRoute Audio route. Refer to AudioRoute{@link #AudioRoute}.
For Android device, the valid audio playback devices may vary due to different audio device connection status. See Set the Audio Route. @return - 0: Success. - < 0 : Fail. See ReturnStatus{@link #ReturnStatus} for more details @note - You can implement most scenarios by calling setDefaultAudioRoute{@link #RTCEngine#setDefaultAudioRoute} and the default audio route switching strategy of the RTC SDK. For details about the strategy, see Set the Audio Route. You should use this API in a few exceptional scenarios like manually switching audio route with external audio device connected. - This interface is only supported in communication mode. - For the volume type in different audio scenarios, refer to AudioScenarioType{@link #AudioScenarioType}.

Implementation

  $i() => ($instance as $p_i.ByteRTCEngine)
      .setAudioRoute(t_AudioRoute.code_to_ios(audioRoute));

  if (Platform.isAndroid) {
    return $a();
  } else if (Platform.isIOS) {
    return $i();
  } else {
    throw UnsupportedError(
        'Not Support Platform ${Platform.operatingSystem}');
