使用AnnotatedRegion是最适合我的，特别是如果我没有AppBar

import 'package:flutter/services.dart';

...

Widget build(BuildContext context) {
   return Scaffold(
      body: AnnotatedRegion<SystemUiOverlayStyle>(
         value: SystemUiOverlayStyle.light,                
         child: ...,
      ),
   );
}

我对所有提到的答案都有问题，除了我自己做的解决方案:容器(宽度:MediaQuery.of(context).size。MediaQuery.of(context).padding. width, height:上衣，颜色:颜色。绿色) 对于视图，哪里没有appBar添加我只是使用容器的背景，准确的高度匹配状态栏的高度。在这个场景中，每个视图可以有不同的状态颜色，我不需要担心和思考一些逻辑，某种错误的视图有某种错误的颜色。

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,
    ),
  );
 }

我不能直接在帖子中评论，因为我还没有必要的声誉，但作者问了以下问题:

唯一的问题是背景是白色的，但时钟，无线和其他文本和图标也是白色的。我不知道为什么!!

对于任何来到这个帖子的人来说，这是对我有用的方法。状态栏的文本颜色由flutter/material.dart中的亮度常数决定。要改变这一点，调整SystemChrome解决方案，如下所示来配置文本:

    SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
      statusBarColor: Colors.red,
      statusBarBrightness: Brightness.dark,
    ));

亮度的可能值为亮度。黑暗和光明。

最好的办法就是不用包装

Scaffold(
      extendBodyBehindAppBar: true,
      appBar: AppBar(
        toolbarHeight: 0,
        backgroundColor: Colors.transparent,
        elevation: 0,
        systemOverlayStyle: const SystemUiOverlayStyle(
          statusBarColor: Colors.transparent, // <-- SEE HERE
          statusBarIconBrightness:
              Brightness.dark, //<-- For Android SEE HERE (dark icons)
          statusBarBrightness: Brightness.light,
        ),
      ),.......

使用这种方法使你的状态栏完全白色的状态栏图标， 我个人使用它!在android上测试工作很好!

import 'package:FileSharing/bodypage.dart';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
          // This is the theme of your application.
          //
          // Try running your application with "flutter run". You'll see the
          // application has a blue toolbar. Then, without quitting the app, try
          // changing the primarySwatch below to Colors.green and then invoke
          // "hot reload" (press "r" in the console where you ran "flutter run",
          // or simply save your changes to "hot reload" in a Flutter IDE).
          // Notice that the counter didn't reset back to zero; the application
          // is not restarted.
          primarySwatch: Colors.blue,
          appBarTheme: AppBarTheme(
            color: Colors.white,
            elevation: 0,
            brightness: Brightness.light,
            centerTitle: true,
            iconTheme: IconThemeData(
              color: Colors.black,
            ),
            textTheme: TextTheme(),
          )

          // This makes the visual density adapt to the platform that you run
          // the app on. For desktop platforms, the controls will be smaller and
          // closer together (more dense) than on mobile platforms.
          ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
      statusBarColor: Colors.white,
    ));
    return Scaffold(
      appBar: AppBar(
        brightness: Brightness.light,
        actions: [
          Container(
            width: 63,
            padding: EdgeInsets.only(right: 30),
            child: FloatingActionButton(
              onPressed: null,
              backgroundColor: Colors.pink,
              elevation: 8,
              child: Icon(Icons.person_pin),
            ),
          )
        ],
      ),
    );
  }
}
