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