Flutter:Inkwell不适用于Card
我正在尝试在卡窗口小部件上实现包装并对其进行包装,但是它根本不起作用。我将Tap保留为null,因为此类使用3个参数,稍后将其填充以生成多个卡。我看不到发生了什么,这阻止了InkWell的崩溃,因此我们将不胜感激。
class FeedBackCardsImage extends StatelessWidget { final String imagePath;
final String cardTitle;
final String cardTag;
FeedBackCardsImage({
this.imagePath,
this.cardTitle,
this.cardTag,
});
@override
Widget build(BuildContext context) {
return InkWell(
child: new Container(
child: new Card(
child: new Padding(
padding: new EdgeInsets.all(15.0),
child: new Column(
children: <Widget>[
new SizedBox(
height: 184.0,
child: new Stack(
children: <Widget>[
new Positioned.fill(
child: new Image.asset(
imagePath,
//package: destination.assetPackage,
fit: BoxFit.contain,
),
),
],
),
),
new Padding(
padding: new EdgeInsets.all(
7.0,
),
child: new Text(
cardTitle,
style: new TextStyle(
fontSize: 14.0,
fontWeight: FontWeight.w600,
color: Colors.black87),
),
),
new Padding(
padding: new EdgeInsets.all(
0.0,
),
child: new Text(
cardTag,
style: new TextStyle(
fontSize: 12.0,
fontWeight: FontWeight.w400,
color: Colors.black54),
),
),
],
),
),
),
),
onTap: null,
);
}
回答:
说明:
“发生的事情是Material规范说飞溅实际上是在Material上的墨水。因此,当我们飞溅时,我们所做的就是从字面上使Material部件执行飞溅。如果您在Material之上有东西,我们溅在它下面,你看不到它。”
解决方法:
return Stack(children: <Widget>[ new Card(
child: new Padding(
padding: new EdgeInsets.all(15.0),
child: new Column(
children: <Widget>[
new SizedBox(
height: 184.0,
child: new Stack(
children: <Widget>[
new Positioned.fill(
child: new Image.asset(
imagePath,
//package: destination.assetPackage,
fit: BoxFit.contain,
),
),
],
),
),
new Padding(
padding: new EdgeInsets.all(
7.0,
),
child: new Text(
cardTitle,
style: new TextStyle(
fontSize: 14.0,
fontWeight: FontWeight.w600,
color: Colors.black87),
),
),
new Padding(
padding: new EdgeInsets.all(
0.0,
),
child: new Text(
cardTag,
style: new TextStyle(
fontSize: 12.0,
fontWeight: FontWeight.w400,
color: Colors.black54),
),
),
],
),
),
),
new Positioned.fill(
child: new Material(
color: Colors.transparent,
child: new InkWell(
onTap: () => null,
)))
]);
