你也可以在SliverAppBar中使用这个，不要忘记使用backwardsCompatibility: false如果你跳过这个属性，它将不起作用。参见doc

@override
  Widget build(BuildContext context) {    
    return Scaffold(
      appBar: null,
      body: CustomScrollView(
        slivers: <Widget>[
          SliverAppBar(
              systemOverlayStyle: SystemUiOverlayStyle(
                  statusBarColor: Colors.transparent,
                  statusBarIconBrightness: Brightness.dark),
              backwardsCompatibility: false,
//... remaining code and close braces..

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。

文档: https://api.flutter.dev/flutter/dart-ui/Brightness-class.html https://api.flutter.dev/flutter/services/SystemUiOverlayStyle-class.html

当您不使用AppBar时，更改状态栏的颜色

首先导入这个

import 'package:flutter/services.dart';

现在使用下面的代码改变状态栏的颜色在你的应用程序，当你不使用AppBar

SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.dark.copyWith(

    statusBarColor: AppColors.statusBarColor,/* set Status bar color in Android devices. */
    
    statusBarIconBrightness: Brightness.dark,/* set Status bar icons color in Android devices.*/
    
    statusBarBrightness: Brightness.dark)/* set Status bar icon color in iOS. */
); 

在iOS中使用安全区域时，更改状态栏的颜色

Scaffold(
  body: Container(
    color: Colors.red, /* Set your status bar color here */
    child: SafeArea(child: Container(
      /* Add your Widget here */
    )),
  ),
); 

你也可以在SliverAppBar中使用这个，不要忘记使用backwardsCompatibility: false如果你跳过这个属性，它将不起作用。参见doc

@override
  Widget build(BuildContext context) {    
    return Scaffold(
      appBar: null,
      body: CustomScrollView(
        slivers: <Widget>[
          SliverAppBar(
              systemOverlayStyle: SystemUiOverlayStyle(
                  statusBarColor: Colors.transparent,
                  statusBarIconBrightness: Brightness.dark),
              backwardsCompatibility: false,
//... remaining code and close braces..

对于那些使用AppBar的人

如果你使用AppBar，那么更新状态栏颜色就像这样简单:

Scaffold(
  appBar: AppBar(
    // Use [Brightness.light] for black status bar 
    // or [Brightness.dark] for white status bar
    // https://stackoverflow.com/a/58132007/1321917
    brightness: Brightness.light 
  ),
  body: ...
)

申请所有应用程序栏:

return MaterialApp(
  theme: Theme.of(context).copyWith(
    appBarTheme: Theme.of(context)
        .appBarTheme
        .copyWith(brightness: Brightness.light),
  ...
  ),

对于那些不使用AppBar的人

用AnnotatedRegion包装您的内容，并将值设置为SystemUiOverlayStyle。light或SystemUiOverlayStyle.dark:

return AnnotatedRegion<SystemUiOverlayStyle>(
  // Use [SystemUiOverlayStyle.light] for white status bar 
  // or [SystemUiOverlayStyle.dark] for black status bar
  // https://stackoverflow.com/a/58132007/1321917
  value: SystemUiOverlayStyle.light,
  child: Scaffold(...),
);

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),
            ),
          )
        ],
      ),
    );
  }
}
