I have a Row widget inside a Card, and I want to divide the Row perfectly in half the width of the card and put some centered text in each half. So the separation in half of the row has to be fixed and each text has to be centered in the half where it is. Here is an example:
Any ideas?
Try this
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Expanded(child: Center(child: TextButton(...))),
VerticalDivider(width: 1.0),
Expanded(child: Center(child: TextButton(...))),
],
),
In my case I tried like this
#override
Widget build(BuildContext context) {
final _screen = MediaQuery.of(context).size;
return Column(
children: [
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Container(
width: _screen.width * 0.45,
child: ...
),
VerticalDivider(width: 1.0),
Container(
width: _screen.width * 0.45,
child: ...
),
]
),
],
);
}

There is a box in which I need to animate a child consisting of a Row in which there are two Text. (In short - running line). Both texts in the result must be on the same line.
The child I want to animate is wider than the parent anyway and when animating, an overflow error pops up.
Overflow error
How can this be avoided?
This is code:
final Widget content = SizedBox(
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: [
Text('TEXT 1'),
Text('TEXT 2')
],
),
);
#override
Widget build(BuildContext context) {
return
Container(
alignment: Alignment.center,
width: widget.parentWidth,
height: UI_SIZE,
child: ClipPath(
clipBehavior: Clip.hardEdge,
child: SlideTransition(
position: _offsetAnimation,
child: content,
),
),
);
}
try this
final Widget content = SizedBox(
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: [
Expanded(child: Text('TEXT 1'),),
Expanded(child: Text('TEXT 2'),),
],
),
);
I was able to fix it with OverflowBox.
final Widget content = OverflowBox(
maxWidth: double.infinity,
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
children: [
Text('TEXT 1'),
Text('TEXT 2')
],
),
);
Maybe someone will help this solution
like the title says is there a way to place a widget on bottom of screen in expanded
Expanded -> SingleChildScrollView() -> column(children: [ -> Container() -> ElevatedButton() ])
i want the ElevatedButton to be placed on the bottom of screen also i don't want to place it away of the Expanded widget, is there a way to do that ?
Expanded(
child: Column(
children: [
Container(),
//use Spacer(),
Spacer(),
ElevatedButton()
],
),
)
try use spacer inside column
SingleChildScrollView(
child: Container(
height: MediaQuery.of(context).size.height - APPBAR_SIZE,
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Container(child: CHILD),
ElevatedButton(),
],
),
),
)
UPDATE:
Column(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Container(
height: MediaQuery.of(context).size.height - APPBAR_SIZE - ElevatedButtonHeight,
child: SingleChildScrollView(
child: Container(child: CHILD),
),
),
ElevatedButton(),
],
),
So I'm working on my first Project. Basically I want to alignment 4 containers equally. they should have same size H/W so i could scroll on them whenever extra data has been put into them later.....
Here's my Code
Widget build(BuildContext context) {
return Center(
child: Scaffold(
body: Center(
child: Padding(
padding: const EdgeInsets.all(20.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Row(
children: [
Row(
children: [
VerticalText1(),
DoBuilder(),
],
),
Column(
children: const [
SizedBox(
width: 10,
)
],
),
Column(
children: [
DecideBuilder(),
],
),
],
),
Row(
children: const [
SizedBox(
height: 10,
)
],
),
Row(
children: [
Row(
children: [
VerticalText2(),
DelegateBuilder(),
],
),
Column(
children: const [
SizedBox(
width: 10,
)
],
),
Align(
alignment: Alignment.bottomLeft,
child: DeleteBuilder(),
),

for me I'm also a beginner in flutter but I know something that if you want actual size for container and you want it to be some kind of responsive you have 2 ways to do that:
first you can use:
(Mediaquery).of(context).size.width or
(media.query).of(context).size.height
that will give you the size of your screen and you can use as much as you need from it for each container for example:
Container(
child:,
width: (MediaQuery.of(context).size.width / 2))
that will give you half of your screen width what ever the device run the app the size will be the same for the screen size
and other way you can use expanded widget:
put every container in expanded widget and give the flex parameter value of one
here is an example:
Row(children:[
Expanded(flex:1,child:Container()),
Expanded(flex:1,child:Container()),]),
expanded will sum the flexes and will divide the space of the screen on element all equal repeat the above code in single Column has 2 Rows and I hope your code will work as you want
Instead of row and column, you should try with the GridView otherwise you can try with media query height and width.
GridView.builder(
itemCount: 4,
gridDelegate:
SliverGridDelegateWithFixedCrossAxisCount(crossAxisCount: 2),
itemBuilder: (BuildContext context, int index) {
return new Card(
child: Container(
color: Colors.green,
child: Center(child: Text("$index"),),
),
);
},
)
And Using Column and row
idget build(BuildContext context) {
double height = MediaQuery.of(context).size.height;
double width = MediaQuery.of(context).size.width-20;
return Scaffold(
appBar: AppBar(
title: Text("widget.title"),
),
body: Stack(
children: [
Column(
children: [
Expanded(
child: Row(
children: [
Container(
height: height / 2,
width: width/2,
color: Colors.green,
),
SizedBox(width: 10,),
Container(
height: height / 2,
width: width / 2,
color: Colors.green,
)
],
),
),
SizedBox(height: 10,),
Expanded(
child: Row(
children: [
Container(
height: height / 2,
width: width / 2,
color: Colors.green,
),
SizedBox(width: 10,),
Container(
height: height / 2,
width: width / 2,
color: Colors.green,
)
],
),
),
],
),
Center(
child: Padding(
padding: const EdgeInsets.only(right:10.0),
child: CircleAvatar(child: Icon(Icons.home),),
),
)
],
),
);
}
Output:
I started to develop in Flutter recently and I am having difficulties in centralizing a Widget completely in the available space of View.
This is how it looks:
And here's what I want to achieve:
And here's my code:
LayoutBuilder(builder:
(BuildContext context, BoxConstraints viewportConstraints) {
return SingleChildScrollView(
child: ConstrainedBox(
constraints: BoxConstraints(
minHeight: viewportConstraints.maxHeight,
),
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
Column(children: [
NavHeader("Deposit"),
BalanceHeader(widget.usd),
]),
Column(
mainAxisSize: MainAxisSize.min,
children: [
Text(
"How much do you want deposit?",
style:(
...
),
),
Container(
alignment: Alignment.center,
width: width * 0.4,
margin: EdgeInsets.only(top: 10),
child: Row(
...
),
),
],
),
],
),
),
);
}),
bottomNavigationBar: BottomAppBar(
...
),
),
);
}
By using MainAxisSize.min The height of the Column will be according to the combined height of its children and incoming height from the parent will be ignored. That means your column height has shrinked to its children.
There is you can use MainAxisSize.max instead of MainAxisSize.min to max height of column. And also you have to use mainAxisAlignment: MainAxisAlignment.center for aligning childrens to center of column.
Your Second Column
Column(
mainAxisSize: MainAxisSize.min,
children: [
Text(
"How much do you want deposit?",
style:(
...
),
),
Container(
alignment: Alignment.center,
width: width * 0.4,
margin: EdgeInsets.only(top: 10),
child: Row(
...
),
),
],
),
Edited Column
Column(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.center
children: [
Text(
"How much do you want deposit?",
style:(
...
),
),
Container(
alignment: Alignment.center,
width: width * 0.4,
margin: EdgeInsets.only(top: 10),
child: Row(
...
),
),
],
),
Well, there is a widget for that!
As for most things in flutter just Wrap the Widgets you want centered inside a Center widget and you should achieve what you want.
Column(
mainAxisAlignment: MainAxisAlignment.center,
children ... Your code
)
You could also wrap your widget with the Column widget and it will work only for the X coordinates.
(It has already been stated but poorly)
I am trying to align column with text to far right side of the window but somehow its not happening.
Tried with MainAxisAlignment.right , CrossAxisAlignment.right but somehow nothing is working out for me. Below is my Dart code,
class MVTHomePage extends StatelessWidget {
#override
Widget build(BuildContext context) {
final height = MediaQuery.of(context).size.height;
final width = MediaQuery.of(context).size.width;
return Scaffold(
body: SingleChildScrollView(
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
Container(
height: 550,
width: width,
child: Row(
children: [
Lottie.network(
'https://assets2.lottiefiles.com/datafiles/6WfDdm3ooQTEs1L/data.json'),
Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Text("Multivariate Testing"),
Text('Run experiments to make key flows more effective.'),
// ignore: deprecated_member_use
TextButton(
onPressed: () {}, child: Text('Create Experiment')),
],
),
],
),
),
Container(
height: height,
width: width,
color: Colors.blueAccent,
)
],
),
));
}
}
I am seeing this in the output
While you are using the Row widget,
Add mainAxisAlignment: MainAxisAlignment.spaceBetween to it.
So your code should be like this
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween, // <-- Add this
children: [
Lottie.network(
When your Row's children are being rendered, by giving it MainAxisAlignment.spaceBetween, we are essentially telling the Row to place its children as far apart from each other as possible.
In the case of 2 children, it means 1 child to the extreme left and other to the extreme right.
