Implementation

@override
void run() async {
  final credFile = OnvifUtil.defaultConfigFile;

  final hasCred = credFile.existsSync();

  String? approval;

  final credentials = <String, dynamic>{};

  if (hasCred) {

    approval = stdin.readLineSync(encoding: Encoding.getByName('utf-8')!);

    //use existing credentials from filesystem
    if (approval != null && approval.startsWith('n')) {
      final content = credFile.readAsStringSync();

      try {
        credentials.addAll(json.decode(content));
      } catch (exception) {
        stderr.write('Error reading the credentials file.\n');

        exit(64);
      }
    }
  }

  print('Host:');
