Flutter - 在溢出时换行文本，如插入省略号或淡入淡出 [英] Flutter - Wrap text on overflow, like insert ellipsis or fade

问题描述

我正在尝试创建一行，其中中心文本具有最大大小，如果文本内容太大，则适合大小.

我插入了 TextOverflow.ellipsis 属性来缩短文本并插入三点 ... 但它不起作用.

ma​​in.dart

import 'package:flutter/material.dart';无效主(){运行应用程序(新的我的应用程序())；}class MyApp 扩展 StatelessWidget {@覆盖小部件构建(BuildContext 上下文){返回新的 MaterialApp(主页:新主页()，);}}class HomePage 扩展了 StatelessWidget {@覆盖小部件构建(BuildContext 上下文)=>新脚手架(应用栏:新的应用栏(背景颜色:新颜色(0xFF26C6DA)，),正文:新的列表视图(孩子们:<小部件>[新卡(孩子:新容器(填充:新的 EdgeInsets.symmetric(水平:16.0，垂直:18.0)，孩子:新行(孩子们:<小部件>[新容器(填充:新的 EdgeInsets.only(右:24.0)，孩子:新的圆形头像(背景颜色:新颜色(0xFFF5F5F5)，半径:16.0，)),新容器(填充:新的 EdgeInsets.only(右:13.0)，孩子:新文本('文本拉...',溢出:TextOverflow.ellipsis，样式:新文本样式(字体大小:13.0，fontFamily: 'Roboto',颜色:新颜色(0xFF212121)，fontWeight: FontWeight.bold,),),),新容器(孩子:新列(crossAxisAlignment: CrossAxisAlignment.end,孩子们:<小部件>[新行(孩子们:<小部件>[新文本('账单  '，样式:新文本样式(字体大小:12.0，fontFamily: 'Roboto',颜色:新颜色(0xFF9E9E9E)),),新文本('$ -999.999.999,95',样式:新文本样式(字体大小:14.0，fontFamily: 'Roboto',颜色:新颜色(0xFF212121)),),],),新行(孩子们:<小部件>[新文本('限制  '，样式:新文本样式(字体大小:12.0，fontFamily: 'Roboto',颜色:新颜色(0xFF9E9E9E)),),新文本('R$ 900.000.000,95',样式:新文本样式(字体大小:14.0，fontFamily: 'Roboto',颜色:新颜色(0xFF9E9E9E)),),],),]))],),)),]));}

结果:

解决方案

您应该将 Container 包装在

灵活(孩子:新容器(填充:新的 EdgeInsets.only(右:13.0)，孩子:新文本('文本大eeeeeeeeeeeeeeeeeeeeee',溢出:TextOverflow.ellipsis，样式:新文本样式(字体大小:13.0，fontFamily: 'Roboto',颜色:新颜色(0xFF212121)，fontWeight: FontWeight.bold,),),),),

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(

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.

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,
      ),
    ),
  ),
),
