颤振-在溢出时换行文本，如插入省略号或渐隐

我试图创建一行，其中中心文本有一个最大大小，如果文本内容太大，它适合大小。

我插入TextOverflow。属性来缩短文本并插入三个点…但这并不奏效。

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(

                            style: new TextStyle(

                            ),
                          ),
                          new Text(
                            '\$ -999.999.999,95',

                        ],
                      ),
                      new Row(

                          ),
                          new Text(
                            'R\$ 900.000.000,95',

其他回答

使用省略号

Text(
  "This is a long text",
  overflow: TextOverflow.ellipsis,
),

使用消失

Text(
  "This is a long text",
  overflow: TextOverflow.fade,
  maxLines: 1,
  softWrap: false,
),

使用夹

Text(
  "This is a long text",
  overflow: TextOverflow.clip,
  maxLines: 1,
  softWrap: false,
),

注意:

如果你在一行中使用文本，你可以像这样把上面的文本放在扩展内:

Expanded(
  child: AboveText(),
)

                        child: Text(
                          "YOUR LONG TEXT HERE...",

你可以这样做

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

您可以使用此代码片段来显示带有省略号的文本

Text(
    "Introduction to Very very very long text",
    maxLines: 1,
    overflow: TextOverflow.ellipsis,
    softWrap: false,
    style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold),
),

根据您的情况，我认为这是以下最好的方法。

final maxWidth = MediaQuery.of(context).size.width * 0.4;
Container(
        textAlign: TextAlign.center,
        child: Text('This is long text',
        constraints: BoxConstraints(maxWidth: maxWidth),
),
