getCheckedInAt method
Will get a collection of PcoCheckInsStation objects (expecting many)
using a path like this: https://api.planningcenteronline.com/check-ins/v2/check_ins/1/checked_in_at
Implementation
Future<PcoCollection<PcoCheckInsStation>> getCheckedInAt(
{PcoCheckInsStationQuery? query}) async {
query ??= PcoCheckInsStationQuery();
var url = '$apiEndpoint/checked_in_at';
return PcoCollection.fromApiCall<PcoCheckInsStation>(url,
query: query, apiVersion: apiVersion);
}
