## Implementation

        animationMilliseconds: entity.animationMilliseconds,
        imageSeconds: entity.imageSeconds,
        items: entity.items == null
            ? null
            : List<ListedItemModel>.from(
                await Future.wait(entity.items!.map((item) {
                counter++;
                return ListedItemModel.fromEntityPlus(counter.toString(), item,
                    appId: appId);
              }).toList())),
