update method

Future<bool> update(T existingData)

Updates _data inside the repository. If the creation is sucessful, will return true. Otherwise, false.

Note: userId is automatically applied to existingData.

Implementation

Future<bool> update(T existingData) async {
  if (!_data.any((element) => element.id == existingData.id) || !isInstanceValid(existingData)) {
    AppEventsDispatcher().publish(OperationFailedEvent(OperationType.update, service.repositoryId, existingData));
    return false;
  }

  if (assignUserIdOnUpdate) {
    existingData = existingData.copyWith(userId: userId) as T;
  }

  _data.replace(existingData);

  await service.update(existingData);

  notifyListeners();
  AppEventsDispatcher().publish(DataUpdatedEvent(service.repositoryId, existingData));

  return true;
}
