我正在尝试改变状态栏的颜色为白色。我偶然发现了这家酒吧。我尝试在我的dart文件中使用示例代码。
当前回答
[Android测试] 这就是为什么我能够使状态栏透明,文本颜色深,
import 'package:flutter/services.dart';
void main() {
SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
statusBarColor: Colors.transparent, // transparent status bar
statusBarIconBrightness: Brightness.dark // dark text for status bar
));
runApp(MyApp());
}
其他回答
使它像你的应用程序栏颜色
import 'package:flutter/material.dart';
Widget build(BuildContext context) {
SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
statusBarColor: Colors.transparent,
systemNavigationBarColor: Colors.transparent,
));
}
最新的解决方案。Flutter 2.0及以上
对于使用AppBar的用户:
/// WORKS on the screen where appBar is used
Scaffold(
appBar: AppBar(
systemOverlayStyle: SystemUiOverlayStyle(
// statusBarColor: Colors.red, // You can use this as well
statusBarIconBrightness: Brightness.dark, // OR Vice Versa for ThemeMode.dark
statusBarBrightness: Brightness.light, // OR Vice Versa for ThemeMode.dark
),
),
),
对于那些不使用AppBar的人:
将下面的代码放在根屏幕的构建功能上,以影响下面的所有屏幕:
void main() {
runApp(MyApp());
}
// This widget is the root of your application.
class MyApp extends StatelessWidget {
/// WORKS on every screen EXCEPT the screen in which appBar is used
SystemChrome.setSystemUIOverlayStyle(
SystemUiOverlayStyle(
// statusBarColor: Colors.red, // You can use this as well
statusBarIconBrightness: Brightness.dark, // OR Vice Versa for ThemeMode.dark
statusBarBrightness: Brightness.light, // OR Vice Versa for ThemeMode.dark
),
);
@override
Widget build(BuildContext context) {}
}
将下面的代码放在单个屏幕的构建功能上,只影响该屏幕:
class SingleScreen extends StatelessWidget {
/// WORKS on a single screen where appBar is NOT used
SystemChrome.setSystemUIOverlayStyle(
SystemUiOverlayStyle(
// statusBarColor: Colors.red, // You can use this as well
statusBarIconBrightness: Brightness.dark, // OR Vice Versa for ThemeMode.dark
statusBarBrightness: Brightness.light, // OR Vice Versa for ThemeMode.dark
),
);
@override
Widget build(BuildContext context) {}
}
在主要的。飞镖文件 导入服务如下
import 'package:flutter/services.dart';
在build方法中,在返回之前添加这一行
SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
statusBarColor: Colors.orange
));
是这样的:
@override
Widget build(BuildContext context) {
SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
statusBarColor: CustomColors.appbarcolor
));
return MaterialApp(
home: MySplash(),
theme: ThemeData(
brightness: Brightness.light,
primaryColor: CustomColors.appbarcolor,
),
);
}
你可以这样做,
SystemChrome.setSystemUIOverlayStyle(
SystemUiOverlayStyle(
statusBarColor: Colors.grey.withOpacity(0.5),
statusBarIconBrightness: Brightness.dark,
statusBarBrightness:
Platform.isAndroid ? Brightness.dark : Brightness.light,
systemNavigationBarColor: Colors.white,
systemNavigationBarDividerColor: Colors.grey,
systemNavigationBarIconBrightness: Brightness.dark,
),
);
将此代码添加到主程序中。省道构建方法,
这是目前为止最好的方法,它不需要额外的插件。
Widget emptyAppBar(){
return PreferredSize(
preferredSize: Size.fromHeight(0.0),
child: AppBar(
backgroundColor: Color(0xFFf7f7f7),
brightness: Brightness.light,
)
);
}
在你的刑台上像这样叫它
return Scaffold(
appBar: emptyAppBar(),
.
