我正在尝试使所有文本(长度不同)在一个固定宽度的框中适合,并且我希望它们在应用 FittedBox 时看起来与最长单词的大小相同。所以我正在做的就是用空白填充单词的其余部分,以使长度与最长的单词相匹配。但这并不完全有效,如下图所示:
这是代码:
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
routes: {
'/': (context) => HomePage(),
},
);
}
}
class HomePage extends StatelessWidget {
final String padding = " " * 5;
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Home'),
),
body: Center(
child: Container(
color: Colors.red,
height: 100.0,
width: 100.0,
padding: const EdgeInsets.all(8.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Center(
child: FittedBox(
fit: BoxFit.scaleDown,
child: Text(
"${padding}Demo$padding",
textAlign: TextAlign.center,
style: TextStyle(color: Colors.black),
),
),
),
Icon(Icons.mic, size: 24.0),
],
),
),
),
);
}
}
你知道这里有什么问题吗?
