getLive method
Will get a collection of PcoServicesLive objects (expecting many)
using a path like this: https://api.planningcenteronline.com/services/v2/service_types/1/plans/1/live
Implementation
Future<PcoCollection<PcoServicesLive>> getLive(
{PcoServicesLiveQuery? query}) async {
query ??= PcoServicesLiveQuery();
var url = '$apiEndpoint/live';
return PcoCollection.fromApiCall<PcoServicesLive>(url,
query: query, apiVersion: apiVersion);
}
