I am trying to implement simple one-two line text.
Text will have a starting text then icon and ending text.Due to different styles i am using row with text,icon and text widgets.
I am getting A RenderFlex overflowed by 16 pixels on the right. error.
i enclose the row in flexible and expanded but still not working. i just want the text to drop at the end of line to next line.
Container(
padding: EdgeInsets.only(
left: 20,
right: 20,
),
width: mdq.size.width,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Expanded(
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Text(
'Tap ',
style: TextStyle(
fontSize: 17,
),
),
Icon(Icons.add),
Text(
'on the right hand corner to start a new chat.',
style: TextStyle(
fontSize: 17,
),
),
],
),
),
Container(
margin: EdgeInsets.symmetric(
vertical: 15,
),
child: Text(
'You can communicate with the user who have installed Just Meetups and Deals app',
style: TextStyle(
color: Colors.grey,
fontSize: 16,
),
),
),
Container(
margin: EdgeInsets.symmetric(
vertical: 15,
),
child: InkWell(
onTap: () {},
child: Text(
'Start communicating',
textAlign: TextAlign.left,
style: TextStyle(
color: Colors.blue,
fontSize: 20,
fontWeight: FontWeight.bold,
),
),
),
),
],
),
);
Use the Expanded widget
Container(
padding: EdgeInsets.only(
left: 20,
right: 20,
),
width: MediaQuery.of(context).size.width,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.start,
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Text(
'Tap ',
style: TextStyle(
fontSize: 17,
),
),
Icon(Icons.add),
Expanded(
child: Text(
'on the right hand corner to start a new chat.',
style: TextStyle(
fontSize: 17,
),
),
)
],
),
Container(
margin: EdgeInsets.symmetric(
vertical: 15,
),
child: Text(
'You can communicate with the user who have installed Just Meetups and Deals app',
style: TextStyle(
color: Colors.grey,
fontSize: 16,
),
),
),
Container(
margin: EdgeInsets.symmetric(
vertical: 15,
),
child: InkWell(
onTap: () {},
child: Text(
'Start communicating',
textAlign: TextAlign.left,
style: TextStyle(
color: Colors.blue,
fontSize: 20,
fontWeight: FontWeight.bold,
),
),
),
),
],
),
),
Here's a codepen of it working
You need not use any flex like [Expanded, Flexible, etc] for rows in the column because rows default takes max-width available by column
You are getting an error because your row child width is more than available screen size
you can use Expanded for the children of large width of rows in Expanded to wrap the child in available width inside a row.
I was trying to use a ListTile to display a small title on the left, and then a longer text in the trailing widget. My idea es to let the trailing text to split out into multiple lines if there is not enough horizontal space.
I also tried to create my own tile using the following code:
Container(
padding: const EdgeInsets.symmetric(horizontal: 20, vertical: 20),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(right: 12),
child: Text(
"Campus",
style: TextStyle(
fontSize: 15,
fontWeight: FontWeight.w700,
),
),
),
Text(
"20h course - New students -",
style: TextStyle(
fontSize: 15,
fontWeight: FontWeight.w400,
),
),
],
),
),
Using this code in a Pixel 2 XL emulator, as there is enough space, everything is in the same line as expected:
But when I'm trying it in a Nexus One emulator, because of its size, here is the output:
In order to allow the text to split in multiples lines, I wrapped the text on the right into a flexible widget:
Container(
padding: const EdgeInsets.symmetric(horizontal: 20, vertical: 20),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(right: 12),
child: Text(
"Campus",
style: TextStyle(
fontSize: 15,
fontWeight: FontWeight.w700,
),
),
),
Flexible(
child: Text(
"20h course - New students -",
style: TextStyle(
fontSize: 15,
fontWeight: FontWeight.w400,
),
),
),
],
),
),
But then the problem is that even though the text is split in two lines, it is using more space than needing, so there is empty space left:
I have also tried to use an align widget to move the text to the end, but no luck either. Any ideas?
Wrap your Text with container and give it alignment left or right. Then the important part is, add textWidthBasis: TextWidthBasis.longestLine, to your Text. Code:
Container(
padding: const EdgeInsets.symmetric(horizontal: 20, vertical: 20),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Padding(
padding: const EdgeInsets.only(right: 12),
child: Text(
"Campus",
style: TextStyle(
fontSize: 15,
fontWeight: FontWeight.w700,
),
),
),
Flexible(
child: Container(
alignment: Alignment.centerLeft,
child: Text(
"20h course - New students - sd f sdfsddssdfsdfs dfs df sf sdf sdf ",
style: TextStyle(
fontSize: 15,
fontWeight: FontWeight.w400,
),
textWidthBasis: TextWidthBasis.longestLine,
),
),
),
],
),
),
Flexible expands to fill all the available space. So if you want both widgets have the same space you can wrap the with flexible. Also you can use softWrap for you text.
Container(
padding: const EdgeInsets.symmetric(horizontal: 20, vertical: 20),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Flexible(
child: Padding(
padding: const EdgeInsets.only(right: 12),
child: Text(
"Campus",
style: TextStyle(
fontSize: 15,
fontWeight: FontWeight.w700,
),
),
),
),
Flexible(
child: Text(
"20h course - New students -20h course - New students -20h course - New students -20h course - New students -20h course - New students -",
softWrap: true,
style: TextStyle(
fontSize: 15,
fontWeight: FontWeight.w400,
),
),
),
],
),
),
You can also use Expanded instead of `Flexible
I have a column with three rows:
#override
Widget build(BuildContext context) {
return GestureDetector(
onTap: () {
print('card of course clicked');
},
child: Card(
shape: RoundedRectangleBorder(borderRadius:
BorderRadius.circular(8.0)),
child: Container(
height: 144,
child: Row(children: [
Padding(
padding: EdgeInsets.all(16.0),
child: ClipRRect(
borderRadius: BorderRadius.all(Radius.circular(8.0)),
child: Image.network(_model._schoolThumb))),
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
SizedBox(height: 16),
Align(
alignment: Alignment.center,
child: Text(_model._schoolName,
style: TextStyle(
color: Colors.black,
fontWeight: FontWeight.w600,
fontSize: 18)),
),
SizedBox(height: 12),
Row(
children: <Widget>[
Icon(Icons.location_on, color: Colors.grey[700]),
Container(width: 8),
Text(_model._guides,
style: TextStyle(
fontSize: 14,
color: Colors.black,
fontWeight: FontWeight.w400)),
],
),
SizedBox(height: 12),
Row(
children: <Widget>[
Icon(Icons.attach_money, color: Colors.grey[700]),
Container(width: 8),
Text(_model._priceFrom,
style: TextStyle(
fontSize: 14,
color: Colors.black,
fontWeight: FontWeight.w400))
],
)
],
)
]),
),
),
);
}
As a result, I have three rows aligned to start.
How can I align the first Text() in the center? Giving properties to the text and wrapping in Expanded, Container, Stack didn't help, or I did it in the wrong way. Thanks in advance!
EDIT
Whole build() method attached
Problem:
By default, the width of the Column is set to the width of the widest child widget of Column.
Solution:
You need to wrap your Column with either Expanded or Flexible.
Like below.
Expanded(
child: Column(
children: <Widget>[
...
],
),
)
or
Flexible(
child: Column(
children: <Widget>[
...
],
),
)
And then need to use the Align or Center widget to set the alignment to your child widget in your case the Text widget.
Like below:
Align(
alignment: Alignment.center,
child: Text(
"Test",
style: TextStyle(
color: Colors.black,
fontWeight: FontWeight.w600,
fontSize: 18,
),
),
),
or
Center(
child: Text(
"Test",
style: TextStyle(
color: Colors.black,
fontWeight: FontWeight.w600,
fontSize: 18,
),
),
),
UPDATE
You haven't given a width to the column so it does not know the remaining width that it can take. So wrap your column in a flexible which will give it the width remaining to expand.
Flexible(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
SizedBox(height: 16),
Row(
I'm trying to create a line in which center text has a maximum size, and if the text content is too large, it fits in size.
I insert the TextOverflow.ellipsis property to shorten the text and inserting the triple points ... but it is not working.
main.dart
import 'package:flutter/material.dart';
void main() {
runApp(new MyApp());
}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return new MaterialApp(
home: new HomePage(),

You should wrap your Container in a Flexible to let your Row know that it's ok for the Container to be narrower than its intrinsic width. Expanded will also work.
Flexible(
child: new Container(
padding: new EdgeInsets.only(right: 13.0),
child: new Text(
'Text largeeeeeeeeeeeeeeeeeeeeeee',
overflow: TextOverflow.ellipsis,
style: new TextStyle(
fontSize: 13.0,
fontFamily: 'Roboto',
color: new Color(0xFF212121),
fontWeight: FontWeight.bold,
),
),
),
),
Using Ellipsis
Text(
"This is a long text",
overflow: TextOverflow.ellipsis,
),
Using Fade
Text(
"This is a long text",
overflow: TextOverflow.fade,
maxLines: 1,
softWrap: false,
),
Using Clip
Text(
"This is a long text",
overflow: TextOverflow.clip,
maxLines: 1,
softWrap: false,
),
Note:
If you are using Text inside a Row, you can put above Text inside Expanded like:
Expanded(
child: AboveText(),
)
First, wrap your Row or Column in Expanded widget
Then
Text(
'your long text here',
overflow: TextOverflow.fade,
maxLines: 1,
softWrap: false,
style: Theme.of(context).textTheme.body1,
)
1. clip
Clip the overflowing text to fit its container.
SizedBox(
width: 120.0,
child: Text(
"Enter Long Text",
maxLines: 1,
overflow: TextOverflow.clip,
softWrap: false,
style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold, fontSize: 20.0),
),
),
Output:
2.fade
Fade the overflowing text to transparent.
SizedBox(
width: 120.0,
child: Text(
"Enter Long Text",
maxLines: 1,
overflow: TextOverflow.fade,
softWrap: false,
style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold, fontSize: 20.0),
),
),
Output:
3.ellipsis
Use an ellipsis to indicate that the text has overflowed.
SizedBox(
width: 120.0,
child: Text(
"Enter Long Text",
maxLines: 1,
overflow: TextOverflow.ellipsis,
softWrap: false,
style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold, fontSize: 20.0),
),
),
Output:
4.visible
Render overflowing text outside of its container.
SizedBox(
width: 120.0,
child: Text(
"Enter Long Text",
maxLines: 1,
overflow: TextOverflow.visible,
softWrap: false,
style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold, fontSize: 20.0),
),
),
Output:

You can use this code snipped to show text with ellipsis
Text(
"Introduction to Very very very long text",
maxLines: 1,
overflow: TextOverflow.ellipsis,
softWrap: false,
style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold),
),
You can do it like that
Expanded(
child: Text(
'Text',
overflow: TextOverflow.ellipsis,
maxLines: 1
)
)
One way to fix an overflow of a Text Widget within a row if for example a chat message can be one really long line. You can create a Container and a BoxConstraint with a maxWidth in it.
Container(
constraints: BoxConstraints(maxWidth: 200),
child: Text(
(chatName == null) ? " ": chatName,
style: TextStyle(
fontWeight: FontWeight.w400,
color: Colors.black87,
fontSize: 17.0),
)
),
You can do that by First wrapping your Column inside Flexible or Expanded and then use Text as usual and it will get wrapped up automatically.
Container(
child: Row(
children: [
Flexible(
child: Column(
children: [
Text("This text is so long and long and long and long and long and that's why it is not wrapping to next line.")
]
),
)
],
),
),
SizedBox(
width: 200.0,
child: Text('PRODUCERS CAVITY FIGHTER 50X140g',
overflow: TextOverflow.ellipsis,
style: Theme.of(context).textTheme.body2))
Just wrap in inside a widget that can take a specific width for it to work or it will assume the width of the parent container.
I went through such a problem several times using rows within columns. Here's a good way to fix it:
return Column(
children: [
Row(
children: const [
Icon(Icons.close, color: Colors.red), // an example icon
// use the flexible widget above the padding
Flexible(
child: Padding(
padding: EdgeInsets.symmetric(horizontal: 10.0),
child: Text(
"Exemple of text",
overflow: TextOverflow.ellipsis, // I used ellipsis, but it works with others (fade, clip, etc.)
maxLines: 1,
),
),
),
],
)
],
);
Notice that I put the Flexible above the padding, because when the text grew, the padding also broke the screen. It would be useless to put it only in Text. Hope this helps.
Wrapping whose child elements are in a row or column, please wrap your column or row is new Flexible();
https://github.com/flutter/flutter/issues/4128
Depending on your situation, I think this is the best approach below.
final maxWidth = MediaQuery.of(context).size.width * 0.4;
Container(
textAlign: TextAlign.center,
child: Text('This is long text',
constraints: BoxConstraints(maxWidth: maxWidth),
),
Use an ellipsis to indicate that the text has overflowed.
SizedBox(
width: 120.0,
child: Text(
"Enter Long Text",
maxLines: 1,
overflow: TextOverflow.ellipsis,
softWrap: false,
style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold, fontSize: 20.0),
),
),
If you simply place text as a child(ren) of a column, this is the easiest way to have text automatically wrap. Assuming you don't have anything more complicated going on. In those cases, I would think you would create your container sized as you see fit and put another column inside and then your text. This seems to work nicely. Containers want to shrink to the size of its contents, and this seems to naturally conflict with wrapping, which requires more effort.
Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Text('This long text will wrap very nicely if there isn\'t room beyond the column\'s total width and if you have enough vertical space available to wrap into.',
style: TextStyle(fontSize: 16, color: primaryColor),
textAlign: TextAlign.center,),
],
),
SizedBox(
width: width-100,
child: Text(
"YOUR LONG TEXT HERE...",
maxLines: 3,
overflow: TextOverflow.clip,
softWrap: true,
style: TextStyle(
fontWeight:FontWeight.bold,
),
),
),
Wrap the Container with Expanded()
Expanded (child: Container(
padding: new EdgeInsets.only(right: 24.0),
child: new CircleAvatar(
backgroundColor: new Color(0xFFF5F5F5),
radius: 16.0,
)
),
new Container(
padding: new EdgeInsets.only(right: 13.0),
child: new Text(
'Text lar...',
overflow: TextOverflow.ellipsis,
style: new TextStyle(
fontSize: 13.0,
fontFamily: 'Roboto',
color: new Color(0xFF212121),
fontWeight: FontWeight.bold,
),
),
),
In Column We make text ellipsis by wraping column with flexibale widget,
Container(
height: SizeConfig.blockSizeVertical * 20,
width: SizeConfig.blockSizeHorizontal * 88,
child: Flexible(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
PicClipper(
height: 50,
width: 50,
circularRadius: 30,
circularImage: imageUrl[index]),
SizedBox(
width: SizeConfig.blockSizeHorizontal * 3,
),
const Text(
fontSize: 12,
fontWeight: FontWeight.normal,
text:
'Lorem ipsum dolor sit amet,consectetur adipiscing elit.Lorem ipsum dolor sit amet,consectetur adipiscing elit.',
fontStyle: FontStyle.normal,
textColor: AppColors.blackTextColor,
overflow: TextOverflow.ellipsis,
fontFamily: "Poppins",
maxLine: 3,
textAlign: TextAlign.start,
),
],
),
),
),
If you are facing the problem inside a Row a widget, try to wrap the Text widget with Expanded
Row(
children: [
Text('first'),
Expanded(
child: Text('a really long message...'),
)
]
)
I think the parent Container needs to be given a maxWidth of the proper size. It looks like the Text box will fill whatever space it is given above.
Text inside Row
1. Preference of text in Column 1 > Column 2
Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: const [
Text(
"This is very very long text in column 1 of Row",
style: TextStyle(
overflow: TextOverflow.ellipsis, backgroundColor: Colors.green),
),
Flexible(
child: Text("This is very very long text in column 2 of Row",
style: TextStyle(
overflow: TextOverflow.ellipsis,
backgroundColor: Colors.yellow)),
)
],
)
2. Preference of text in Column 2 > Column 1
Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: const [
Flexible(
child: Text(
"This is very very long text in column 1 of Row",
style: TextStyle(overflow: TextOverflow.ellipsis, backgroundColor: Colors.green),
),
),
Text("This is very very long text in column 2 of Row",
style: TextStyle(overflow: TextOverflow.ellipsis, backgroundColor: Colors.yellow))
],
)
3. Same Preference
Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: const [
Flexible(
child: Text(
"This is very very long text in column 1 of Row",
style: TextStyle(
overflow: TextOverflow.ellipsis, backgroundColor: Colors.green),
),
),
Flexible(
child: Text("This is very very long text in column 2 of Row",
style: TextStyle(
overflow: TextOverflow.ellipsis,
backgroundColor: Colors.yellow)),
)
],
)
Text inside Column
define the maxLine attribute.
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: const [
Text(
"This is very very very very very very very very very very very very very very very very very long text in Row 1 of Column",
maxLines: 2,
style: TextStyle(
backgroundColor: Colors.green, overflow: TextOverflow.ellipsis),
),
Text("This is very very long text in Row 2 of Column",
style: TextStyle(
overflow: TextOverflow.ellipsis,
backgroundColor: Colors.yellow))
],
)
Note: If your requirement is to show the entrie content without overflow but not messing with the constraints, remove the overflow attribute but keep the Flexible as is:
Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: const [
Flexible(
child: Text(
"This is very very long text in column 1 of Row",
style: TextStyle(backgroundColor: Colors.green),
),
),
Flexible(
child: Text("This is very very long text in column 2 of Row",
style: TextStyle(
overflow: TextOverflow.ellipsis,
backgroundColor: Colors.yellow)),
)
],
)
In Row We make text ellipsis to go second line by wraping firstly Text with Container and than wrap container with flexible widget
Container(
height: SizeConfig.blockSizeVertical * 10,
width: SizeConfig.blockSizeHorizontal * 88,
child: Row(
crossAxisAlignment:
CrossAxisAlignment.start,
children: [
PicClipper(height: 50, width:50, circularRadius: 30, circularImage:imageUrl[index]),
SizedBox(
width:
SizeConfig.blockSizeHorizontal * 3,
),
Flexible(
child: Container(
child: const
AppText
(
fontSize: 12,
fontWeight: FontWeight.normal,
text:
'Lorem ipsum dolor sit amet,consectetur adipiscing elit.Lorem ipsum dolor sit amet,consectetur adipiscing elit.',
fontStyle: FontStyle.normal,
textColor: AppColors.blackTextColor,
textOverflow: TextOverflow.ellipsis,
fontFamily: "Poppins",
maxLine: 3,
textAlign: TextAlign.start,
),
),
),
],
),
),
There is a very simple class TextOneLine from package assorted_layout_widgets.
Just put your text in that class.
For example:
Row(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
SvgPicture.asset(
loadAsset(SVG_CALL_GREEN),
width: 23,
height: 23,
fit: BoxFit.fill,
),
SizedBox(width: 16),
Expanded(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
TextOneLine(
widget.firstText,
style: findTextStyle(widget.firstTextStyle),
textAlign: TextAlign.left,
),
SizedBox(height: 4),
TextOneLine(
widget.secondText,
style: findTextStyle(widget.secondTextStyle),
textAlign: TextAlign.left,
),
],
),
),
Icon(
Icons.arrow_forward_ios,
color: Styles.iOSArrowRight,
)
],
)
Try:
Expanded(
child: Container(
child: Text('OVER FLOW TEST TEXTTTT',
overflow: TextOverflow.fade)),
),
This will show OVER FLOW. If there is an overflow, it will be handled.
