Default to 0, which means no exposure compensation. @return - 0: Success. - < 0: Failure. See ReturnStatus{@link #ReturnStatus} for more details. @note - You must call startVideoCapture{@link #RTCEngine#startVideoCapture} to start SDK internal video capturing, and use SDK internal rendering before calling this API. - The camera exposure compensation setting will be invalid after calling stopVideoCapture{@link #RTCEngine#stopVideoCapture} to stop internal capturing.

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