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
  ));
}

我认为这对你有帮助:

SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
        systemNavigationBarColor: Colors.white, // navigation bar color
        statusBarColor: Colors.white, // status bar color
        statusBarIconBrightness: Brightness.dark, // status bar icons' color
        systemNavigationBarIconBrightness: Brightness.dark, //navigation bar icons' color
    ));

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

以下是你需要知道的一切:

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

void main() {
  SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
    systemNavigationBarColor: Colors.amber, // navigation bar color
    statusBarColor: Colors.white, // status bar color
    statusBarIconBrightness: Brightness.dark, // status bar icon color
    systemNavigationBarIconBrightness: Brightness.dark, // color of navigation controls
  ));
  runApp(MyApp());
}

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: ...,
      ),
   );
}

使它像你的应用程序栏颜色

import 'package:flutter/material.dart';

 Widget build(BuildContext context) {
  SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
      statusBarColor: Colors.transparent,
      systemNavigationBarColor: Colors.transparent,
  ));
 }
