Implementation

Future<ListThingTypesResponse> listThingTypes({
  int? maxResults,
  String? nextToken,
  String? thingTypeName,
}) async {
  _s.validateNumRange(
    'maxResults',
    maxResults,
    1,
    250,
  );
  _s.validateStringLength(
    'thingTypeName',
    thingTypeName,
    1,
    128,
  );
  final $query = <String, List<String>>{
    if (maxResults != null) 'maxResults': [maxResults.toString()],
    if (nextToken != null) 'nextToken': [nextToken],
    if (thingTypeName != null) 'thingTypeName': [thingTypeName],
  };
  final response = await _protocol.send(
    payload: null,
    method: 'GET',
    requestUri: '/thing-types',
    queryParams: $query,
    exceptionFnMap: _exceptionFns,
