使用一个Stack小部件将多个小部件堆叠在一起

class Example extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Stack(
      overflow: Overflow.clip,
      children: [
        Container(
            decoration: BoxDecoration(
                borderRadius: BorderRadius.circular(30),
                color: Colors.lightBlue[200]),
            child: SizedBox(
              height: 350,
              width: 350,
              child: Text('Test'),
            )),
        Divider(
          color: Colors.red,
          thickness: 2,
        )
      ],
    );
  }
}
