点击容器触发onTap()处理程序,但不会显示任何墨水飞溅效果。
class _MyHomePageState extends State<MyHomePage> {
@override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: new Text(widget.title),
),
body: new Center(
child: new InkWell(
onTap: (){print("tapped");},
child: new Container(
width: 100.0,
height: 100.0,
color: Colors.orange,
),
),
),
);
}
}
我试着把InkWell放在容器里,但徒劳。
循环部件的解决方案,如下所示:
Material(
color: Colors.transparent,
child: Container(
alignment: Alignment.center,
height: 100,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
IconButton(
enableFeedback: true,
iconSize: 40,
icon: Icon(
Icons.skip_previous,
color: Colors.white,
size: 40,
),
onPressed: () {}),
IconButton(
iconSize: 100,
enableFeedback: true,
splashColor: Colors.grey,
icon: Icon(Icons.play_circle_filled, color: Colors.white, size: 100),
padding: EdgeInsets.all(0),
onPressed: () {},
),
IconButton(
enableFeedback: true,
iconSize: 40,
icon: Icon(
Icons.skip_next,
color: Colors.white,
size: 40,
),
onPressed: () {}),
],
),
),
)
现在使用MaterialButton,在更新的版本颤振
Widget build(BuildContext context) {
return Padding(
padding: const EdgeInsets.symmetric(horizontal: 16.0),
child: MaterialButton(
child: Text(
labelText,
style: TextStyle(fontSize: 22),
),
onPressed: () {},
color: backgroundColor,
height: 45,
minWidth: double.infinity,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(
Radius.circular(16),
),
),
),
);
}
