2. BookletEntity? entity

)

## Implementation

    static Future<BookletModel?> fromEntity(
        String documentID, BookletEntity? entity) async {
      if (entity == null) return null;
      var counter = 0;
      return BookletModel(
        documentID: documentID,
        appId: entity.appId ?? '',
        description: entity.description,
        sections: entity.sections == null
            ? null
            : List<SectionModel>.from(
                await Future.wait(entity.sections!.map((item) {
                counter++;
                return SectionModel.fromEntity(counter.toString(), item);
              }).toList())),
        conditions: await StorageConditionsModel.fromEntity(entity.conditions),
      );
    }
