getCheckedOutBy method

Will get a collection of PcoCheckInsPerson objects (expecting many) using a path like this: https://api.planningcenteronline.com/check-ins/v2/check_ins/1/checked_out_by

Implementation

Future<PcoCollection<PcoCheckInsPerson>> getCheckedOutBy(
    {PcoCheckInsPersonQuery? query}) async {
  query ??= PcoCheckInsPersonQuery();
  var url = '$apiEndpoint/checked_out_by';
  return PcoCollection.fromApiCall<PcoCheckInsPerson>(url,
      query: query, apiVersion: apiVersion);
}
