Implementation

@override
void run() async {
  await initializeOnvif();

  final users = <User>[];

  final hasFile = argResults?.options.contains('users-file') ?? false;

  final hasUser = (argResults?.options.contains('username') ?? false) &&

  if (hasFile) {
    final userFile = File(argResults!['users-file']);

    if (!userFile.existsSync()) {
      throw UsageException(
          '${argResults!['users-file']} - file not found', usage);
    }

    users.addAll((loadYaml(userFile.readAsStringSync()) as YamlList)
        .map((userJson) => User.fromYamlMap(userJson))
        .toList());
  }

  if (hasUser) {
