getTags method
Will get a collection of PcoServicesTag objects (expecting many)
using a path like this: https://api.planningcenteronline.com/services/v2/songs/1/arrangements/1/tags
Implementation
Future<PcoCollection<PcoServicesTag>> getTags(
{PcoServicesTagQuery? query}) async {
query ??= PcoServicesTagQuery();
var url = '$apiEndpoint/tags';
return PcoCollection.fromApiCall<PcoServicesTag>(url,
query: query, apiVersion: apiVersion);
}
