getEvent method
Will get a collection of PcoCalendarEvent objects (expecting one)
using a path like this: https://api.planningcenteronline.com/calendar/v2/event_instances/1/event_times/1/event
Implementation
Future<PcoCollection<PcoCalendarEvent>> getEvent(
{PcoCalendarEventQuery? query}) async {
query ??= PcoCalendarEventQuery();
var url = '$apiEndpoint/event';
return PcoCollection.fromApiCall<PcoCalendarEvent>(url,
query: query, apiVersion: apiVersion);
}
