get method
Gets a custom list.
Request parameters:
customListId - Required. The ID of the custom list to fetch.
Value must have pattern ^\[^/\]+$.
advertiserId - The ID of the DV360 advertiser that has access to the
fetched custom lists.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a CustomList.
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<CustomList> get(
  core.String customListId, {
  core.String? advertiserId,
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if (advertiserId != null) 'advertiserId': [advertiserId],
    if ($fields != null) 'fields': [$fields],
  };
  final url_ = 'v2/customLists/' + core.Uri.encodeFull('$customListId');
  final response_ = await _requester.request(
    url_,
    'GET',
    queryParams: queryParams_,
  );
  return CustomList.fromJson(
    response_ as core.Map<core.String, core.dynamic>,
  );
