parse method

TranslateArgResults parse(List<String> args)

Parses the given args and returns the parsed results as a TranslateArgResults object.

Throws a FormatException if there is an unexpected positional argument. Returns a TranslateArgResults object containing the parsed results.

Implementation

TranslateArgResults parse(List<String> args) {
  final rawResults = _parser.parse(args);

  if (rawResults.rest.isNotEmpty) {
    throw FormatException(
      'Unexpected positional argument "${rawResults.rest.first}".',
    );
  }

  final modelProvider = rawResults.wasParsed(_modelProviderKey)
      ? ModelProvider.values.firstWhereOrNull(
          (provider) => provider.key == rawResults[_modelProviderKey],
        )
      : null;
  final model = rawResults.wasParsed(_modelKey)
      ? Model.values.firstWhereOrNull(
          (model) => model.key == rawResults[_modelKey],
        )
      : null;
  final excludeLocales = rawResults.wasParsed(_excludeLocalesKey)
      ? rawResults[_excludeLocalesKey] as List<String>
      : null;
