Solution:

In the itemBuilder of the ListView.builder, in the build() method of the _ItemsScreenState class in the items_screen.dart file, add a Dismissible widget, as follows:

itemBuilder: (BuildContext context, int index) {

return Dismissible(

key: Key(items[index].name),

onDismissed: (direction) {

String strName = items[index].name;

helper.deleteItem(items[index]);

setState(() {

items.removeAt(index);

});

Scaffold.of(context)

.showSnackBar(SnackBar(content: Text("$strName

deleted")));

},

child: ListTile(

The app is now complete. There's only one more step to perform: making sure that it works as expected.
