如何更改 Flutter 中的系统导航栏颜色

Question

I want to change the colour of the system navigation bar but I can't.我想更改系统导航栏的颜色，但我不能。

I got this:我懂了：

 import 'package:flutter/services.dart'
    SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.light);

but it didn't work for me...但这对我不起作用...

I used the code below to change the status bar colour it worked.我使用下面的代码来更改它工作的状态栏颜色。

import 'package:flutter/services.dart'
systemOverlayStyle: SystemUiOverlayStyle(statusBarColor: Colors.white),

In your MaterialApp, you should change the primaryColor:在您的 MaterialApp 中，您应该更改主要颜色：

MaterialApp(
  theme: ThemeData(primaryColor: Colors.grey,),
  home: AppHome(),
),
