  int? maxResults,
  String? nextToken,
}) async {
  _s.validateNumRange(
    'maxResults',
    maxResults,
    1,
    250,
  );
  final $query = <String, List<String>>{
    if (maxResults != null) 'maxResults': [maxResults.toString()],
    if (nextToken != null) 'nextToken': [nextToken],
  };
  final response = await _protocol.send(
    payload: null,
    method: 'GET',
    requestUri: '/things/${Uri.encodeComponent(thingName)}/principals',
    queryParams: $query,
