Flutter - Wrap text on overflow, like insert ellipsis or fade

问题

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,

                    ),
                  ),
                ),
                new Container(
                  child: new Column(
                    crossAxisAlignment: CrossAxisAlignment.end,
                    children: <Widget>[
                      new Row(

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.

            new 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(),
)

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),
),

回答4:

You can do it like that

Expanded(
   child: Text(
   'Text',
   overflow: TextOverflow.ellipsis,
   maxLines: 1
   )
)

回答5:

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.

回答6:

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

回答7:

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.

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),
                )
            ),

回答9:

first, wrap your Row or Column in a Flexible or Expanded widget then

Text(
    'your long text here',
    overflow: TextOverflow.fade,
    maxLines: 1,
    softWrap: false,
    style: Theme.of(context).textTheme.body1,
)
