@override
Future<Map<String, dynamic>?> open(String url, Map<String, dynamic> params) async {
  try {
    final result = await methodChannel.invokeMethod<Map<dynamic, dynamic>>(
      'open',
      {'url': url, 'params': params}
    );

    // Convert the dynamic map to a String, dynamic map
    return result?.map((key, value) => MapEntry(key.toString(), value));
  } on PlatformException catch (e) {
    return {
      'status': 'error',
      'code': e.code,
      'message': e.message ?? 'An unknown error occurred',
      'response': e.details
