Implementation
async.Future<Empty> batchDelete(
  BatchDeleteRegionsRequest request,
  core.String parent, {
  core.String? $fields,
}) async {
  final body_ = convert.json.encode(request);
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };
  final url_ =
      'accounts/v1/' +
      core.Uri.encodeFull('$parent') +
      '/regions:batchDelete';
  final response_ = await _requester.request(
    url_,
    'POST',
    body: body_,
    queryParams: queryParams_,
  );
  return Empty.fromJson(response_ as core.Map<core.String, core.dynamic>);
