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)
),

The answer is
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.
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,
),
),
),
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),
)
),
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.
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,
),
),
),
There are many answers but Will some more observation it.
1. clip
Clip the overflowing text to fix 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),
),
),

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),
),
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.
Wrapping whose child elements are in a row or column, please wrap your column or row is new Flexible();
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
)
)
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,
)
],
)
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,
)
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(),
)
