在Flutter中如何在GridView中显示图片？
我想在GridView中显示一组图片。但是我无法做到这一点。我想知道从资源中获取一组图片的数据类型以及构造函数在这种情况下如何帮助。我刚开始学习Flutter，不知道如何使用它。
class Home extends StatefulWidget {
final String title;
Home({this.title}) : super();
@override
_HomeState createState() => _HomeState();
}
@override
Widget build(BuildContext context) {
var gridView = new GridView.builder(
itemCount: 20,
gridDelegate:
new SliverGridDelegateWithFixedCrossAxisCount(crossAxisCount: 3),
itemBuilder: (BuildContext context, int index) {
return new GestureDetector(
child: new Card(
elevation: 10,
child: new Container(
// child: *Image list as child*, but don't know about the list datatype hence not created it!
alignment: Alignment.center,
),
),
onTap: () {},
);
});
return new Scaffold(
appBar: new AppBar(
backgroundColor: Colors.red,
title: new Text("Flutter TabBar"),
),
body: Container(
padding: EdgeInsets.all(10),
child: gridView,
),
);
}
}
