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(),
);
}
}
class HomePage extends StatelessWidget {
#override
Widget build(BuildContext context) => new Scaffold(
appBar: new AppBar(
backgroundColor: new Color(0xFF26C6DA),
),
body: new ListView (
children: <Widget>[
new Card(
child: new Container(
padding: new EdgeInsets.symmetric(horizontal: 16.0, vertical: 18.0),
child: new Row(
children: <Widget>[
new 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,
),
),
),
new Container(
child: new Column(
crossAxisAlignment: CrossAxisAlignment.end,
children: <Widget>[
new Row(
children: <Widget>[
new Text(
'Bill ',
style: new TextStyle(
fontSize: 12.0,
fontFamily: 'Roboto',
color: new Color(0xFF9E9E9E)
),
),
new Text(
'\$ -999.999.999,95',
style: new TextStyle(
fontSize: 14.0,
fontFamily: 'Roboto',
color: new Color(0xFF212121)
),
),
],
),
new Row(
children: <Widget>[
new Text(
'Limit ',
style: new TextStyle(
fontSize: 12.0,
fontFamily: 'Roboto',
color: new Color(0xFF9E9E9E)
),
),
new Text(
'R\$ 900.000.000,95',
style: new TextStyle(
fontSize: 14.0,
fontFamily: 'Roboto',
color: new Color(0xFF9E9E9E)
),
),
],
),
]
)
)
],
),
)
),
]
)
);
}
result:
expected:
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),
),
),

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();

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.
