return Scaffold(
      backgroundColor: STATUS_BAR_COLOR_HERE,
      body: SafeArea(
        child: scaffoldBody(),
      ),
);

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。

 return Scaffold(
      backgroundColor: STATUS_BAR_COLOR_HERE,
      body: SafeArea(
        child: scaffoldBody(),
      ),
);

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,
    )

如果你想改变整个应用程序的状态颜色，你可以像这样使用primaryColorDark属性:

void main() {
  runApp(
    MaterialApp(
      home: HomeWidget(),
      theme: ThemeData(
        primaryColorDark: Colors.white,
      ),
    ),
  );
}

完整的示例

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

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      debugShowCheckedModeBanner: false,
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key, required this.title}) : super(key: key);

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return AnnotatedRegion<SystemUiOverlayStyle>(
      value: const SystemUiOverlayStyle(
        systemNavigationBarColor: Colors.red, // navigation bar color
        systemNavigationBarIconBrightness: Brightness.light, //navigation bar icons' color
      ),
      child: Scaffold(
        appBar: AppBar(
          backgroundColor: Colors.red,
          title: const Text('data'),
          systemOverlayStyle: SystemUiOverlayStyle.dark.copyWith(
            statusBarColor: Colors.red,
            statusBarIconBrightness: Brightness.light,
          ),
        ),
      ),
    );
  }
}
