flutter - dart - 颤动单个子滚动视图更改屏幕的小部件布局
问题描述
我正在尝试使用单个子滚动视图小部件使我的颤动页面可滚动。但是在这样做之后，屏幕的整个小部件布局就搞砸了。下面我附上了我的应用程序的屏幕截图，它显示了我想要发生的事情，而不是在我使用单个子滚动视图小部件后发生的事情。

解决方案
您可以使用ListView
class _DriverBioScreenState extends State<DriverBioScreen> {
@override
Widget build(BuildContext context) {
return Scaffold(
body: ListView(
children: [
Container(
height: 1500,
width: MediaQuery.of(context).size.width,
child: Stack(
children: [
Container(
height: 250,

child: ClipRRect(
borderRadius: BorderRadius.circular(30),
child: Image(
image: AssetImage(

Padding(
padding: EdgeInsets.symmetric(vertical: 30, horizontal: 20),
