        future: DBHelper.instance.getItems(),
        builder: (BuildContext context, AsyncSnapshot<List<Model>> snapshot) {
          if (!snapshot.hasData) {
            return Container();
          }
          return snapshot.data!.isEmpty
            ? Container()
            : ListView(

                .where((item) => true) 
                .map((item) => Model(
                  id: item.id,
                  title: item.title,
                  ...,
