【问题描述】:
我正在尝试在 Flutter Web 应用程序上显示一行长文本,而不进行剪辑或省略。为此,我想让它水平滚动。我从https://www.geeksforgeeks.org/flutter-scrollable-text/找到了这段代码
import 'package:flutter/material.dart';
void main() {
runApp(MaterialApp(
home: Scaffold(
//adding App Bar
appBar: AppBar(
backgroundColor: Color.fromRGBO(15, 157, 88, 1),
title: Text(
"GeeksForGeeks",
style: TextStyle(
color: Colors.white,
),
),
),
body: MyApp(),
),
));
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Center(
child: Container(
// adding margin
margin: const EdgeInsets.all(15.0),
// adding padding
padding: const EdgeInsets.all(3.0),
decoration: BoxDecoration(
// adding borders around the widget
border: Border.all(
color: Colors.blueAccent,
width: 5.0,
),
),
// SingleChildScrollView should be
// wrapped in an Expanded Widget
child: Expanded(
//contains a single child which is scrollable
child: SingleChildScrollView(
//for horizontal scrolling
scrollDirection: Axis.horizontal,
child: Text(
"GeeksForGeeks is a good platform to learn programming."
" It is an educational website.",
style: TextStyle(
color: Colors.green,
fontWeight: FontWeight.bold,
fontSize: 20.0,
letterSpacing: 3,
wordSpacing: 3,
),
),
),
),
),
);
}
}
但这对我不起作用。文本被剪裁但不可滚动。我尝试将 overflow: TextOverflow.visible 添加到 Text 小部件,但没有结果。我没有任何其他想法,因为将 Text 包装在 SingleChildScrollView 中是我能想到的解决此问题的最简单的方法。

您的代码运行良好,也可以滚动。
