Dismissible
A widget that can be dismissed by dragging in the indicated direction.
Example
final items = List<String>.generate(3, (i) => "Item ${i + 1}"); Widget build(BuildContext context) { final title = 'Dismissing Items'; return MaterialApp( title: title, theme: ThemeData( primarySwatch: Colors.blue, ), home: Scaffold( appBar: AppBar( title: Text(title), ), body: ListView.builder( itemCount: items.length, itemBuilder: (context, index) { final item = items[index]; return Dismissible( // Each Dismissible must contain a Key. Keys allow Flutter to // uniquely identify widgets. key: Key(item), // Provide a function that tells the app // what to do after an item has been swiped away. onDismissed: (direction) { // Remove the item from the data source. setState(() { items.removeAt(index); }); // Then show a snackbar. Scaffold.of(context) .showSnackBar(SnackBar(content: Text("$item dismissed"))); }, // Show a red background as the item is swiped away. background: Container(color: Colors.red), child: ListTile(title: Text('$item')), ); }, ), ), ); }
