你可以在Android上使用:

 import 'package:flutter/services.dart';

void main() {
  SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
    systemNavigationBarColor: Colors.blue, // navigation bar color
    statusBarColor: Colors.pink, // status bar color
  ));
}

你可以在Android上使用:

 import 'package:flutter/services.dart';

void main() {
  SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
    systemNavigationBarColor: Colors.blue, // navigation bar color
    statusBarColor: Colors.pink, // status bar color
  ));
}

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

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,
    ),
  );
 }

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 */
    )),
  ),
);
