@override Widget build(BuildContext context) { return new Scaffold( appBar: new AppBar( title: new Text('Title'), ), body: new ListView.builder(itemBuilder: (context, index) { return new ListItem(); }), ); } class ListItem extends StatefulWidget { @override State<StatefulWidget> createState() => new _ItemView(); } class _ItemView extends State<ListItem>{ bool isFavorite = false; @override Widget build(BuildContext context) { return new ListTile( trailing: InkWell( child: Icon(Icons.share), ), leading: InkWell( onTap: () { isFavorite = !isFavorite; setState(() { }); }, child: isFavorite ? Icon( Icons.favorite, color: Colors.red, ): Icon(Icons.favorite)), title: new Text('Your Text', style: new TextStyle( fontWeight: FontWeight.bold, fontSize: 14.0)), ); } } |
