为什么appBar的字体比body
Why is the appBar font weight more than in the body
当我尝试 运行 我的 Flutter 应用程序(在 windows 上)时,我发现 appBar 标题权重大于 body 文本权重(即使它们是相同的字体)
This is what I mean - the appBar weight is more than the weight of the text on the body
我的代码如下所示:
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return MaterialApp(
theme: ThemeData(fontFamily: 'SegoeUIVar'),
debugShowCheckedModeBanner: false,
title: 'Hello World',
home: Scaffold(
appBar: PreferredSize(
preferredSize: const Size.fromHeight(32.0),
child: AppBar(
elevation: 0,
backgroundColor: const Color.fromARGB(230, 30, 31, 28),
centerTitle: true,
title: const Text("Hello World", style: TextStyle(fontSize: 15, fontFamily: 'SegoeUIVar')),
)
),
body: const Center(
child: Text('Hello World'),
),
),
);
}
}
在flutter中,每个widget都有自己的主题,所以即使分配了不同的fontFamily,fontWeight也会默认为那个widgets的主题。要分配相同的 fontWweight,您需要在 TextStyle 或实际主题中执行此操作
Text(
'Hello',
style: TextStyle(fontWeight: FontWeight.bold),
),
)
