ios_enumerateAudioCaptureDevices method

Future<ByteRTCDeviceCollection?> ios_enumerateAudioCaptureDevices()

@platform ios @detail api @author dixing @brief 获取音频采集设备列表。 @return 音频采集设备列表。详见 ByteRTCDeviceCollection{@link #ByteRTCDeviceCollection}。
等待超时后会返回空列表。超时时间默认为 10 s。建议通过 rtcEngine:onAudioDeviceStateChanged:device_type:device_state:device_error:{@link #ByteRTCEngineDelegate#rtcEngine:onAudioDeviceStateChanged:device_type:device_state:device_error} 监听到 ByteRTCMediaDeviceListUpdated 后，再次调用本接口获取。 @note 你可以在收到 rtcEngine:onAudioDeviceStateChanged:device_type:device_state:device_error:{@link #ByteRTCEngineDelegate#rtcEngine:onAudioDeviceStateChanged:device_type:device_state:device_error} 了解设备变更后，重新调用本接口以获得新的设备列表。

Implementation

Future<$p_i.ByteRTCDeviceCollection?>
    ios_enumerateAudioCaptureDevices() async {
  $() => ($instance as $p_i.ByteRTCAudioDeviceManager)
      .enumerateAudioCaptureDevices();

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