_grocery\_list\_screen.dart_

**Dismissable** has the key:

```auto
return Dismissible(
            key: Key(item.id),

```

And **InkWell** is the child of that Dismissible widget whose child is a **GroceryTile** :

```auto
            child: InkWell(
              child: GroceryTile(
                key: Key(item.id),

```

The _key_ parameter seems to be redundant for the stateless GroceryTile widget here.  
If you delete it from the code, the app still seems to work perfectly (adding/editing/deleting items seem to work well).

Please advise,
