适用于iOS和Android

import 'package:flutter/services.dart';

@override
Widget build(BuildContext context) {
  SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.dark);

  return Scaffold();
}
    

你可以改变它没有appbar给脚手架(backgroundColor: color);如果你把身体包裹起来，问题可能就解决了。我的意思是这个解决方案不是实践，但如果你不使用appbar，你可以用这种方式实现。

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,
    ),
  );
 }

我通过改变整个背景颜色来解决这个问题，如下所示:

在主界面:

return Scaffold(
      backgroundColor: Colors.black,
      body: SafeArea(
     ),
);

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) {}
}

对我有用的方法(适用于那些不用AppBar的人)

添加AppbBar首选颜色，然后设置:toolbarHeight: 0

 child: Scaffold(
    appBar: AppBar(
      toolbarHeight: 0,
      backgroundColor: Colors.blue,
      brightness: Brightness.light,
    )
