我正在构建一个 flutter 应用程序，我试图在其中添加一个容器及其子文本。 我希望容器的高度与文本要求的一样高。但它取而代之的是指定的高度。
以下是我的代码:
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: [
Container(
height: MediaQuery.of(context).size.width * 0.1,
width: MediaQuery.of(context).size.width * 0.1,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(30),
color: Theme.of(context).primaryColor,
image: DecorationImage(
fit: BoxFit.fill,
image: NetworkImage(imageurl)),
boxShadow: [
BoxShadow(
blurRadius: 25,
color: Colors.black.withOpacity(0.2),
offset: Offset(0, 10),
)
],
),
),
Container(
height: MediaQuery.of(context).size.width * 0.15,
width: MediaQuery.of(context).size.width * 0.5,
padding: EdgeInsets.symmetric(horizontal: 10),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
name,
style: TextStyle(
fontSize: 15,
color: Colors.lightBlue[900],
fontWeight: FontWeight.bold),
),
Text(email),
SizedBox(
height: 2,
),
Row(
children: [
Icon(
Icons.remove_red_eye_outlined,
size: 12,
),
Text(
'View Profile',
style: TextStyle(
fontSize: 12,
),
)
],
)
],
),
),
],
)),
decoration: BoxDecoration(
color: Colors.white,
),
),
),
],
),
),
body: SingleChildScrollView(
scrollDirection: Axis.vertical,
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Container(
height: MediaQuery.of(context).size.height * 0.35,
child: Stack(children: [

child: Align(
alignment: Alignment.topCenter,
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: [
GestureDetector(
onTap: () {
_scaffoldkey.currentState.openDrawer();
},
child: new Container(
child: Icon(
Icons.menu,
color: Colors.white,
size: MediaQuery.of(context).size.height *
0.04,
),
padding: new EdgeInsets.all(7.0),
),
),
SizedBox(
width: MediaQuery.of(context).size.width * 0.3,
),
Container(
height:
MediaQuery.of(context).size.height * 0.07,
child: Center(
child: Text(
'Profile',
style: TextStyle(
color: Colors.white,

),
),
),
SizedBox(
width: MediaQuery.of(context).size.width * 0.3,

),

))),
),
),
),
SizedBox(
width: MediaQuery.of(context).size.width * 0.05,
),
Column(
children: [
Container(
height: MediaQuery.of(context).size.height * 0.08,
child: Text(
'Bill Gates',
style: TextStyle(
fontSize: 25,
color: Colors.white,
fontWeight: FontWeight.bold,
fontFamily: 'Calibri'),
),
),
],
)
],
),
),
Positioned(
top: MediaQuery.of(context).size.height * 0.24,
left: MediaQuery.of(context).size.height * 0.165,
child: FittedBox(
fit: BoxFit.fill,
child: Container(
height: MediaQuery.of(context).size.height * 0.09,
width: MediaQuery.of(context).size.width * 0.6,
child: Text(
'Bill Gates welcomes you. Welcome to Microsoft. It gives me immense pleasure to announce Josh Hazlewood as it\'s new CEO. It is always immense pleasure to work with them. looking foward to have a great time with him.',
style: TextStyle(
color: Colors.black, fontFamily: 'Calibri'),
),
),
),
),
]),
),
],
)),
],
),
));
}
图片如下:
我希望根据此处输入的信息包装包含“Bill Gates”下方文本的容器。
整个容器应该减少，因为我计划在这个自定义应用栏下方添加小部件，那么有什么办法可以实现吗？
我尝试使用 flexible 但它没有用。有人可以帮我解决这个问题吗？
最佳答案
使用适合的盒子:-
FittedBox(
fit:BoxFit.fitHeight,
child:Text("Your text"),
),
