@override
Future<Map<String, dynamic>> authenticate({
  required String title,
  String? subtitle,
  String? description,
  String negativeButtonText = 'Cancel',
  bool confirmationRequired = false,
  bool allowDeviceCredential = false,
  String biometricStrength = 'strong',

    'negativeButtonText': negativeButtonText,
    'confirmationRequired': confirmationRequired,
    'allowDeviceCredential': allowDeviceCredential,

  final result = await methodChannel.invokeMethod<Map>('authenticate', args);
  return Map<String, dynamic>.from(result ?? {});
