Implementation

Future<bool> deleteEvent(String key) async {
  String? regexKey, currentAtsign;
  EventNotificationModel? eventData;
  currentAtsign = EventService().atClientManager.atClient.getCurrentAtSign();
  regexKey = await getRegexKeyFromKey(key);
  if (regexKey == null) {
    throw Exception('Event key not found');
  }
  eventData = await getValue(regexKey);
  print('eventData to delete:$eventData');

  if (eventData!.atsignCreator != currentAtsign) {
    throw Exception('Only creator can delete the event');
  }

  try {
    var atKey = EventService().getAtKey(regexKey);
    var result = await EventService().atClientManager.atClient.delete(atKey);
    // ignore: unnecessary_null_comparison
    if (result != null && result) {}
    return result;
  } catch (e) {
    return false;
  }
