我正在构建一个flutter应用程序,我试图在其中添加一个容器和它的子文本。我希望容器的高度与文本所需的高度相同。但它却采用了指定的高度。
下面是我的代码:
class ChangePassword extends StatefulWidget {
@override
_ChangePasswordState createState() =>
_ChangePasswordState();
}
class _ChangePasswordState extends State<ChangePassword> {
final GlobalKey<ScaffoldState> _scaffoldkey = new GlobalKey<ScaffoldState>();
@override
Widget build(BuildContext context) {
// TODO: implement build
return Scaffold(
key: _scaffoldkey,
drawer: Drawer(
child: ListView(
// Important: Remove any padding from the ListView.
padding: EdgeInsets.zero,
children: <Widget>[
Container(
height: (MediaQuery.of(context).size.height * 0.23),
child: DrawerHeader(
child: Container(
padding:
EdgeInsets.symmetric(horizontal: 10, vertical: 10),
child: Row(
children: [

boxShadow: [
BoxShadow(
blurRadius: 25,

],

Container(

我希望包含“Bill Gates”下面文本的容器根据在那里输入的信息进行 Package 。
整个容器应该减少,因为我计划在这个定制的应用程序栏下面添加小部件,所以有什么方法可以实现这一点?
我试着用弹性的,但是不起作用。有人能帮我一下吗?

使用合适的 Package 盒:-

不要提供容器的高度,它会自动调整。

@安基特,
罪犯:
正如您提到的,
Container
小部件旨在采用您显式指定的宽度和高度,因此它会执行您告诉它的操作。在上述情况下,您应该避免为包含
Text
小部件的Container
指定高度,如下所示。将此代码部分更改为:
到下面的代码,其中我已经删除了指定容器的
height
属性:通过这样做,并将
Container
Package 在FittedBox
中,变化的文本长度Text
小工具将导致它相应地调整其高度。以下部分在此非常重要:

可以使用flexible将文本小部件的高度换行,如下所示
