fetched negative keyword list belongs.
Value must have pattern ^\[^/\]+$.
negativeKeywordListId - Required. The ID of the negative keyword list to
fetch.

Implementation
async.Future<NegativeKeywordList> get(
  core.String advertiserId,
  core.String negativeKeywordListId, {
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };
  final url_ =
      'v4/advertisers/' +
      core.Uri.encodeFull('$advertiserId') +
      '/negativeKeywordLists/' +
      core.Uri.encodeFull('$negativeKeywordListId');
  final response_ = await _requester.request(
    url_,
    'GET',
    queryParams: queryParams_,
  );
  return NegativeKeywordList.fromJson(
    response_ as core.Map<core.String, core.dynamic>,
  );
