How to Adjust container height according to the text height in flutter?
I am building a flutter application where I am trying to add a container and it's child text. I want the container to take as much height as the text requires. But instead it takes the height specified.
Following is my code:
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: [

child: Align(

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(

SizedBox(

))),
),
),
),
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'),
),
),
),
),
]),
),
],
)),
],
),
));
}
Following is the image:
I want the container that contains the text below 'Bill Gates' to be wrapped according to the information entered there.
The whole container should decrease as I am planning to add widgets below this customised appbar, so is there any way I can achieve this?
I tried to use flexible but it did not work. Can someone help me with this please?

You can use flexible to wrap the height of the text widget like this
Flexible(
child: Container(
child: Text(
'This text will determine the height of the row item',
style: TextStyle(fontSize: 16),
),
),
),

@Ankit,
Culprit:
As you mentioned, the Container widget is intended to take the width and height you explicitly specify, so it does what you tell it to do.
What you should have done in the above case is avoid specifying the height for that Container which contains the Text widget as follows.
Change this code section from:
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'),
),
),
),
),
To the following code, where I have removed specifying the height property of the container:
Positioned(
top: MediaQuery.of(context).size.height * 0.24,
left: MediaQuery.of(context).size.height * 0.165,
child: FittedBox(
fit: BoxFit.height,
child: Container(
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'),
),
),
),
),
By doing that, and wrapping the Container within a FittedBox, that varying text length Text widget will cause it to adjust its height accordingly.
Following part is important here:
child: FittedBox(
fit: BoxFit.height,

Do not provide the height of the container and it will adjust automatically.

Use fitted box:-
FittedBox(
fit:BoxFit.fitHeight,
child:Text("Your text"),
),
