I have a row with two component in as Card as follows:
Card(child:Row(
mainAxisAlignment: MainAxisAlignment.center,
children:[
Text("Col 1"),
SizedBox(width: 10),
Text("Col 2"),
])
)
Though the whole row content is horizontally centered in the screen, it expands the whole width where I'd like it to shrink to the space it really needs.
How to do that?
Simply add
mainAxisSize: MainAxisSize.min,
to the Row. So like
Card(child:Row(
mainAxisSize: MainAxisSize.min,
mainAxisAlignment: MainAxisAlignment.center,
children:[
Text("Col 1"),
SizedBox(width: 10),
Text("Col 2"),
])
)
Using the Expanded widget seems like your best bet, as it will shrink the row whilst ensuring that it's aligned in the center.
Card(
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Expanded(
flex: 1,
child: Text("Col 1"),
),
SizedBox(width: 10),
Expanded(
flex: 1,
child: Text("Col 2"),
),
],
),
)
Is there a way to achieve this layout with flutter? With one Column expanded, and the other Column shrink to fit the texts inside, within a Row.
I'm from a web background, I know I can do it with Flex-grow and Flex-shring along with whitespace:nowrap.
I would like to achieve this layout
But in flutter I tried:
This will give me two equal width columns:
Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Expanded(
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.stretch,
mainAxisSize: MainAxisSize.min,
children: [Text('Monthly Membership'), Text('Subscription')],
),
),
Flexible(
fit: FlexFit.tight,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.stretch,
mainAxisSize: MainAxisSize.min,
children: [
Text(
'+100',
maxLines: 1,
softWrap: false,
overflow: TextOverflow.fade,
),
Text(
'18 Sept 2021',
maxLines: 1,
softWrap: false,
overflow: TextOverflow.fade,
),
],
),
),
],
);
This will give an error.

Your code-snippet just works fine, just missing alignment.
About your desire UI, you just need to set alignment.
Card(
color: Colors.grey,
child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Expanded(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceAround,
crossAxisAlignment: CrossAxisAlignment.start,
mainAxisSize: MainAxisSize.min,
children: const [
Text('Monthly Membership'),
SizedBox(height: 10),
Text('Subscription'),
],
),
),
),
Flexible(
fit: FlexFit.tight,
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceAround,
crossAxisAlignment: CrossAxisAlignment.end,
mainAxisSize: MainAxisSize.min,
children: const [
Text(
'+100',
maxLines: 1,
softWrap: false,
overflow: TextOverflow.fade,
),
SizedBox(height: 10),
Text(
'18 Sept 2021',
maxLines: 1,
softWrap: false,
overflow: TextOverflow.fade,
),
],
),
),
),
],
),
),
Your second attempt fails because CrossAxisAlignment.stretch takes all of the horizontal space available, but a Row gives its children an unbounded width constraint. This forces the column to have infinite width, which is impossible. There are two options to fix this:
Use a different crossAxisAlignment
This will make each child of the Column take as much space as it's going to take. Based on your image, you probably want CrossAxisAlignment.center, which will center the column's children. The column will take its width from the larger of the two Text widgets.
Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
// ...
Use IntrinsicWidth
IntrinsicWidth will measure the width that the Column wants to be, then give it that width. This will give the Column a tight width constraint in a second layout pass, which will make CrossAxisAlignment.stretch work as intended.
IntrinsicWidth(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.stretch,
// ...
Both options will layout the second column with unbounded width, which means that if you have very long text, it might make the first column very small. If you want to bound the width of the column, you can add a ConstrainedBox to either solution.
I am trying to use space between to separate two Text widgets but none of mainAxisAlignment options works.
Screenshot of code below.
In the picture, you can see Text2 and Text3 are glued together I want them separated. First child in main Row needs to be expanded 1. Second (the problematic one) needs to be like expanded 0.
Container(
color: Colors.blue,
child: Row(
children: [
Expanded(
child: Container(
color: Colors.orange,
child: Text('Text1'),
),
flex: 1,
),
Column(
children: [
Row(
children: [Text('Text2'), Text('Text3')],
),
Text('Long text Long text Long text'),
],
)
],
),
)
so I realized you used Expanded widget for the first child but not for the second. Also, you need to add mainAxisAlignment: MainAxisAlignment.spaceBetween to the Row widget. Below is a complete code for what you want to achieve.
Container(
color: Colors.blue,
child: Row(
children: [
Expanded(
child: Container(
color: Colors.orange,
child: Text('Text1'),
),
flex: 1,
),
Expanded(
child: Column(
children: [
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Text('Text2'),
Text('Text3')
],
),
Text('Long text Long text Long text'),
],
),
)
],
),
)
Use mainAxisAlignment to spaceBetween
Row(
mainAxisAlignment:MainAxisAlignment.spaceBetween,
children: [Text('Text2'), Text('Text3')],
),
Use Spacer() between two Text.
Text("Text2"),
Spacer(),
Text("Text3")
In my layout I have two Widgets in a row, one text and the an icon.
As shown below, assume that * refers to the icon, and using "-" to represent the row:
----------------------------
Text *
----------------------------
How do I make my text centered in the entire row, and the icon to the right end ?
The main thing you need to notice is that if you don't want to use Stack you should provide same width-consuming widgets both on left and right.
I would do this with either Expanded and Padding
Row(
children: <Widget>[
Expanded(
child: Padding(
padding: const EdgeInsets.only(left: 32.0),
child: Text(
"Text",
textAlign: TextAlign.center,
),
),
),
Icon(Icons.add, size: 32.0,)
],
)
or with Row's mainAxisAlignment and a SizedBox
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
const SizedBox(width: 32.0),
Text("Text"),
Icon(Icons.add, size: 32.0)
],
)
or with Expanded and a SizedBox on the left instead of the padding :). The padding or extra container on the left is so that the textAlign will truly center the text in the row taking into account the space taken up by the Icon.
Simply use Expanded and Spacer widgets on left/right side and put your widget inside the Expanded:
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Spacer(),
Text('Text'),
Expanded(
child: Text('*'),
),
),
],
),
Result:
1. Using Row (not very flexible though)
Row(
children: <Widget>[
Expanded(child: Center(child: Text('Center'))),
Text("#"),
],
)
2. Using Stack (flexible)
IntrinsicHeight(
child: Stack(
children: [
Align(child: Text('Center')),
Positioned(right: 0, child: Text('#')),
],
),
)
I found it necessary to use a Stack to get Text to be truly centered:
Column(
mainAxisSize: MainAxisSize.min,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: [
Stack(
alignment: Alignment.center,
children: [
Align(
alignment: Alignment.center,
child: Text('Text'),
),
Align(
alignment: Alignment.centerRight,
child: Text('*'),
)
],
),
],
);
For flexibility reasons I recommend to use Expanded widgets:
Row(
children: [
Expanded(flex: 1, child: Container()),
Expanded(
flex: 8,
child: Text('Your Text',
textAlign: TextAlign.center,
),
),
Expanded(flex: 1, child: IconButton(...))
],
)
For my case, I solved my centering problem by adjusting the flex property of the Spacer widget -
Row(children: [
Spacer(flex: 3),//3 was for my case, It might be changed for your widgets
Text('Center'),
Spacer(flex: 1),//1 was also for my case, It might be changed on for your widgets
Text("*")]);
Add another icon in the start and set the opacity to zero.
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
CloseButton(
onPressed: () => Navigator.of(context).pop(),
),
Text('text',),
Opacity(
opacity: 0,
child: Icon(Icons.close),
),
],
)
This worked for me without Stack. But it is the other way around. "Text" goes to left "*" goes to center:
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Expanded(
child: Text("text",
style: Theme.of(context).textTheme.caption),
),
Text("*"),
Spacer(),
],
)
I am trying to align two items at extremes one on the left and one on the right.
I have one row that is aligned to the left and then a child of that row is aligned to the right. However it seems the child row is picking up the alignment property from its parent. This is my code
var SettingsRow = new Row(
mainAxisAlignment: MainAxisAlignment.end,
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Text("Right",softWrap: true,),
],
);
var nameRow = new Row(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Text("Left"),
SettingsRow,
],
);
as a result I get something like this
Left Right
What I would like is
Left Right
Also there is enough space on the Row. My question is why is the child Row not exhibiting its MainAxisAlignment.end property ?
Use a single Row instead, with mainAxisAlignment: MainAxisAlignment.spaceBetween.
new Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
new Text("left"),
new Text("right")
]
);
Or you can use Expanded
new Row(
children: [
new Text("left"),
new Expanded(
child: settingsRow,
),
],
);
A simple solution would be to use Spacer() between the two widgets
Row(
children: [
Text("left"),
Spacer(),
Text("right")
]
);
You can do it in many ways.
Using mainAxisAlignment: MainAxisAlignment.spaceBetween
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
FlutterLogo(),
FlutterLogo(),
],
);
Using Spacer
Row(
children: <Widget>[
FlutterLogo(),
Spacer(),
FlutterLogo(),
],
);
Using Expanded
Row(
children: <Widget>[
FlutterLogo(),
Expanded(child: SizedBox()),
FlutterLogo(),
],
);
Using Flexible
Row(
children: <Widget>[
FlutterLogo(),
Flexible(fit: FlexFit.tight, child: SizedBox()),
FlutterLogo(),
],
);
Output:
Yes CopsOnRoad is right, through stack you can align one on right and other at center.
Stack(
children: [
Align(
alignment: Alignment.centerRight,
child: Text("right"),
),
Align(
alignment: Alignment.center,
child: Text("center"),
)
],
)
I had multiple entries in my row, and the accepted answer didn't work for me.
I needed to wrap the final entry in an Align.
I had :
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
...allMyLeftAlignedChildren,
Expanded(
child: myRightAlignedChild,
And I needed :
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
...allMyLeftAlignedChildren,
Expanded(
child: Align( // <--- these 2 lines fixed it
alignment: Alignment.centerRight, // <--- these 2 lines fixed it
child: myRightAlignedChild,
use the line of code mainAxisAlignment: MainAxisAlignment.spaceBetween, in a Row. That will allow The widgets to be on two extremes. However if you are working on TextField, use decoration class and the attribute prefix*** and suffix*** instead
Using Flexing Widget
Row(
children: [
Text(
'1',
style: TextStyle(
fontSize: 18, color: Colors.black),
),
Flexible(fit: FlexFit.tight, child: SizedBox()),
Text(
'10',
style: TextStyle(
fontSize: 18, color: Colors.black),
),
],
),
