@override
Future<String?> generateFileDeviceIdentifier({
  String fileName = 'device_id.txt',
  String folderName = 'DeviceIdentifier',
}) async {
  final result = await methodChannel.invokeMethod<String>(
    'generateFileDeviceIdentifier',
    {'fileName': fileName, 'folderName': folderName},
  );
  return result;
}
