  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };

  final url_ = 'walletobjects/v1/transitObject/' +
      commons.escapeVariable('$resourceId') +
      '/downloadRotatingBarcodeValues';

  final response_ = await _requester.request(
    url_,
    'GET',
    queryParams: queryParams_,
    downloadOptions: downloadOptions,
  );
  if (downloadOptions.isMetadataDownload) {
