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',

修复一行内文本部件溢出的一种方法,例如聊天消息可以是很长的一行。你可以创建一个Container和一个带有maxWidth的BoxConstraint。

            Container(
              constraints: BoxConstraints(maxWidth: 200),
                child: Text(
                  (chatName == null) ? " ": chatName,
                  style: TextStyle(
                      fontWeight: FontWeight.w400,
                      color: Colors.black87,
                      fontSize: 17.0),
                )
            ),

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,
      ),
    ),
  ),
),

我认为父容器需要被赋予适当大小的maxWidth。看起来文本框会填充上面给出的任何空间。

如果您在Row a小部件中遇到问题,请尝试用Expanded包装Text小部件

Row(
  children: [
    Text('first'),
    Expanded(
      child: Text('a really long message...'),
    )
  ]
)

    SizedBox(
                        width: width-100,
                        child: Text(
                          "YOUR LONG TEXT HERE...",
                          maxLines: 3,
                          overflow: TextOverflow.clip,
                          softWrap: true,
                          style: TextStyle(
                            fontWeight:FontWeight.bold,
                          ),
                        ),
                      ),
