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(
                            '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(

                              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)
                            ),
                          ),

其他回答

我多次使用列中行来解决这样的问题。这里有一个解决这个问题的好方法:

 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,
            ),
          ),
        ),
      ],
    )
  ],
);

注意，我将Flexible放在填充的上方，因为当文本增加时，填充也会破坏屏幕。只把它放在文本中是没有用的。希望这能有所帮助。

你应该用一个Flexible来包装你的容器，让你的行知道容器比它的固有宽度窄是可以的。扩展也可以。

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,
      ),
    ),
  ),
),

你可以先将你的列包装在Flexible或Expanded中，然后像往常一样使用Text，它会自动包装。

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.")
          ]
        ),
      )
    ],
  ),
),

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),
),

Try:

 Expanded(
  child: Container(
      child: Text('OVER FLOW TEST TEXTTTT',
          overflow: TextOverflow.fade)),
),

这将显示OVER FLOW。如果有溢出，将会被处理。
