listReferences method
Lists references of an address group.
Request parameters:
addressGroup - Required. A name of the AddressGroup to clone items to.
Must be in the format projects|organization / * /locations/{location}/addressGroups / * .
Value must have pattern
^projects/\[^/\]+/locations/\[^/\]+/addressGroups/\[^/\]+$.
pageSize - The maximum number of references to return. If unspecified,
server will pick an appropriate default. Server may return fewer items
than requested. A caller should only rely on response's next_page_token to
determine if there are more AddressGroupUsers left to be queried.
pageToken - The next_page_token value returned from a previous List
request, if any.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a ListAddressGroupReferencesResponse.
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<ListAddressGroupReferencesResponse> listReferences(
  core.String addressGroup, {
  core.int? pageSize,
  core.String? pageToken,
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if (pageSize != null) 'pageSize': ['${pageSize}'],
    if (pageToken != null) 'pageToken': [pageToken],
    if ($fields != null) 'fields': [$fields],
  };
  final url_ =
      'v1/' + core.Uri.encodeFull('$addressGroup') + ':listReferences';
  final response_ = await _requester.request(
    url_,
    'GET',
    queryParams: queryParams_,
  );
  return ListAddressGroupReferencesResponse.fromJson(
    response_ as core.Map<core.String, core.dynamic>,
  );
