list method
Use this method to list routes created for a private connectivity configuration in a project and location.
Request parameters:
parent - Required. The parent that owns the collection of Routess.
Value must have pattern
^projects/\[^/\]+/locations/\[^/\]+/privateConnections/\[^/\]+$.
filter - Filter request.
orderBy - Order by fields for the result.
pageSize - Maximum number of Routes to return. The service may return
fewer than this value. If unspecified, at most 50 Routes will be returned.
The maximum value is 1000; values above 1000 will be coerced to 1000.
pageToken - Page token received from a previous ListRoutes call.
Provide this to retrieve the subsequent page. When paginating, all other
parameters provided to ListRoutes must match the call that provided the
page token.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a ListRoutesResponse.
Completes with a commons.ApiRequestError if the API endpoint returned an error.
If the used http.Client completes with an error when making a REST call,
this method will complete with the same error.
Implementation
async.Future<ListRoutesResponse> list(
  core.String parent, {
  core.String? filter,
  core.String? orderBy,
  core.int? pageSize,
  core.String? pageToken,
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if (filter != null) 'filter': [filter],
    if (orderBy != null) 'orderBy': [orderBy],
    if (pageSize != null) 'pageSize': ['${pageSize}'],
    if (pageToken != null) 'pageToken': [pageToken],
    if ($fields != null) 'fields': [$fields],
  };
  final url_ = 'v1/' + core.Uri.encodeFull('$parent') + '/routes';
  final response_ = await _requester.request(
    url_,
    'GET',
    queryParams: queryParams_,
  );
  return ListRoutesResponse.fromJson(
    response_ as core.Map<core.String, core.dynamic>,
  );
