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,

                    ),
                  ),
                ),
                new Container(
                  child: new Column(

定义maxLine属性。

在包选型layout_widgets中有一个非常简单的类TextOneLine。

把你的课文放在那堂课上。

例如:

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,
      )
    ],
  )

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(),
)

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。

在列中，我们通过使用flexibale widget包装列来实现文本省略，

 Container(

            width: SizeConfig.blockSizeHorizontal * 88,
            child: Flexible(
              child: Column(
                crossAxisAlignment: CrossAxisAlignment.start,
                children: [
                  PicClipper(
                      height: 50,
