run method

@override Future<CommandStatus> run(Iterable<String> args)

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<CommandStatus> run(Iterable<String> args) async {
  try {
    final _argResults = parse(args);
    return await runCommand(_argResults) ?? CommandStatus.success;
  } on FormatException catch (e, stackTrace) {
    _logger.e(e.message, e, stackTrace);
    _logger.i(usage);
    return CommandStatus.warning;
  } on UsageException catch (e) {
    _logger.e(e.message);
    _logger.i(usage);
    return CommandStatus.warning;
  }
}
