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，

在我的应用程序中完全正常

import 'package:flutter_statusbarcolor/flutter_statusbarcolor.dart';

void main() => runApp(new MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    FlutterStatusbarcolor.setStatusBarColor(Colors.white);
    return MaterialApp(
      title: app_title,
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: HomePage(title: home_title),
    );
  }
}

乌利希期刊指南: 推荐解决方案(Flutter 2.0及以上)

SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
  statusBarColor: Colors.white
));

它可以通过两个步骤来实现:

使用FlutterStatusbarcolor包将状态栏颜色设置为与页面背景相匹配 使用AppBar设置状态栏按钮(电池，wifi等)的颜色。亮度的财产

如果你有一个AppBar:

  @override
  Widget build(BuildContext context) {
    FlutterStatusbarcolor.setStatusBarColor(Colors.white);
    return Scaffold(
      appBar: AppBar(
        brightness: Brightness.light,
        // Other AppBar properties
      ),
      body: Container()
    );
  }

如果你不想在页面中显示应用程序栏:

  @override
  Widget build(BuildContext context) {
    FlutterStatusbarcolor.setStatusBarColor(Colors.white);
    return Scaffold(
      appBar: AppBar(
        brightness: Brightness.light,
        elevation: 0.0,
        toolbarHeight: 0.0, // Hide the AppBar
      ),
      body: Container()
  }

这(在脚手架内部)创建了一个带有浅色内容的黑色状态栏。(没有Appbar)

appBar: AppBar(
      toolbarHeight: 0,
      backgroundColor: Colors.black,
      systemOverlayStyle: SystemUiOverlayStyle.light,
    ),

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,
    )

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..
