# FaderEntity constructor Null safety

FaderEntity(

1. {required String? appId,
2. String? description,
3. int? animationMilliseconds,
4. int? imageSeconds,
5. List<ListedItemEntity>? items,
6. BackgroundEntity? background,
7. StorageConditionsEntity? conditions}

)

## Implementation

    FaderEntity({
      required this.appId,
      this.description,
      this.animationMilliseconds,
      this.imageSeconds,
      this.items,
      this.background,
      this.conditions,
    });
