getNotes method
Will get a collection of PcoGroupsEventNote objects (expecting many)
using a path like this: https://api.planningcenteronline.com/groups/v2/events/1/notes
Implementation
Future<PcoCollection<PcoGroupsEventNote>> getNotes(
{PcoGroupsEventNoteQuery? query}) async {
query ??= PcoGroupsEventNoteQuery();
var url = '$apiEndpoint/notes';
return PcoCollection.fromApiCall<PcoGroupsEventNote>(url,
query: query, apiVersion: apiVersion);
}
