setRemoteRoomAudioPlaybackVolume method

Future<int?> setRemoteRoomAudioPlaybackVolume(int volume)

@detail api @author zhangcaining @brief Adjusts the audio playback volume from all the remote users in a room. @param volume Ratio(%) of playback volume to original volume, in the range 0, 400, with overflow protection.
To ensure the audio quality, we recommend setting the volume to 100.
- 0: mute - 100: original volume. Default value. - 400: Up to 4 times the original volume (with overflow protection) @return - 0: Success. - < 0 : Fail. See ReturnStatus{@link #ReturnStatus} for more details @note Suppose a remote user A is always within the range of the target user whose playback volume will be adjusted,
- If you use both this method and setRemoteAudioPlaybackVolume{@link #RTCEngine#setRemoteAudioPlaybackVolume}, the volume that the local user hears from user A is the volume set by the method called later. - If you use both this method and setPlaybackVolume{@link #RTCEngine#setPlaybackVolume}, the volume that the local user hears from user A is the overlay of both settings.

Implementation

Future<int?> setRemoteRoomAudioPlaybackVolume(int volume) async {
  $a() =>
      ($instance as $p_a.RTCRoom).setRemoteRoomAudioPlaybackVolume(volume);
  $i() => ($instance as $p_i.ByteRTCRoom)
      .setRemoteRoomAudioPlaybackVolume(volume);

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