run method

@override Future<void> run(Iterable<String> args, { Directory? directory, })

Parses args and invokes Command.run on the chosen command.

This always returns a Future in case the command is asynchronous. The Future will throw a UsageException if args was invalid.

Implementation

@override
Future<void> run(Iterable<String> args, {Directory? directory}) async {
  ArgResults results = args.isEmpty ? parse(['check']) : parse(args);

  Ansi? ansi;
  if (results.wasParsed('color')) {
    ansi = Ansi(results['color']);
  }

  logger ??= Logger.standard(ansi: ansi);

  if (results['version']) {
    _out('$appName version $appVersion');
    return Future.value();
  }

  if (results['directory'] != null) {
    Directory dir = Directory(results['directory']);
    if (!dir.existsSync()) {
      String message = 'Directory specified does not exist "${dir.path}".';
      _out('Error: $message');
      throw UsageException(message, usage);
    }
    directory = dir;
  }

  String sdkPath =
      results.wasParsed('dart-sdk') ? results['dart-sdk'] : getSdkPath();

  directory ??= Directory.current;

  if (results['verbose']) {
    logger = Logger.verbose(ansi: ansi);
  }

  project = Project(directory, sdkPath, logger!);

  return runCommand(results);
}
