Future<void> setFlashMode(FlashMode flashMode) async {
  if (currentFlashMode == flashMode) {
    log("flash mode same with current condition");
    return;
  }
  await cameraController?.setFlashMode(flashMode);
  currentFlashMode = flashMode;
  log("successfully update flashMode to $flashMode");
  if (_onFlashModeChanged != null) {
    _onFlashModeChanged?.call(flashMode);
  }
}
