如何使 Flutter ListView 像图片一样具有边框半径

Question

Hi I am making a project but I need to customize listview box like in picture which I included. I tried many options but I could not do that.

class Butgerlist extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    final title = 'Grid List';

    return MaterialApp(
      title: title,
      home: Scaffold(
        appBar: AppBar(
          title: Text(title),
        ),
        body: GridView.count(
          crossAxisCount: 2,
          children: <Widget>[
            Container(
              child: const Center(
                child: (Text("box1")),
              ),
              color: Colors.red,
            ),
            Container(
              child: Text("box2"),
              color: Colors.yellow,
            ),
            Container(
              child: Text("box3"),
              color: Colors.orange,
            ),
            Container(
              child: Text("box4"),
              color: Colors.blue,
            ),
          ],
        ),
      ),
    );
  }
}

I want to make my listview like this. If you have any suggestions please let me know. thank you.

Instead of Container you should have used Card and wrapped it with Padding widget.

This should work for you:

class MyApp extends StatelessWidget {
  static const title = 'Title';
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    final border = RoundedRectangleBorder(
      borderRadius: BorderRadius.circular(10.0),
    );
    final padding = const EdgeInsets.all(4.0);
    return MaterialApp(
      title: title,
      home: Scaffold(
        appBar: AppBar(
          title: Text(title),
        ),
        body: GridView.count(
          crossAxisCount: 2,
          children: <Widget>[
            Padding(
              padding: padding,
              child: Card(
                shape: border,
                color: Colors.red,
                child: const Center(child: (Text("box1"))),
              ),
            ),
            Padding(
              padding: padding,
              child: Card(
                shape: border,
                child: Text("box2"),
                color: Colors.yellow,
              ),
            ),
            Padding(
              padding: padding,
              child: Card(
                shape: border,
                child: Text("box3"),
                color: Colors.orange,
              ),
            ),
            Padding(
              padding: padding,
              child: Card(
                shape: border,
                child: Text("box4"),
                color: Colors.blue,
              ),
            ),
          ],
        ),
      ),
    );
  }
}
