@override Future<T?> create(String? correlationId, T? item)

Implementation

@override
Future<T?> create(String? correlationId, T? item) async {
  var clone_item;
  if (item is ICloneable) {
    clone_item = (item as ICloneable).clone();
  } else {
    var jsonMap = json.decode(json.encode(item));
    clone_item = TypeReflector.createInstanceByType(T, []);
    clone_item.fromJson(jsonMap);
  }

  if (clone_item.id == null) {
    ObjectWriter.setProperty(clone_item, 'id', IdGenerator.nextLong());
  }

  items.add(clone_item);
  logger.trace(correlationId, 'Created item %s', [clone_item.id]);
  await save(correlationId);
  return clone_item;
}
