如何改变状态栏颜色颤振?

我正在尝试改变状态栏的颜色为白色。我偶然发现了这家酒吧。我尝试在我的dart文件中使用示例代码。

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 */
    )),
  ),
);

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());
}

适用于iOS和Android

import 'package:flutter/services.dart';

@override
Widget build(BuildContext context) {
  SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.dark);

  return Scaffold();
}

最新的解决方案。Flutter 2.0及以上

对于使用AppBar的用户:

/// WORKS on the screen where appBar is used
Scaffold(
      appBar: AppBar(
        systemOverlayStyle: SystemUiOverlayStyle(
          // statusBarColor: Colors.red, // You can use this as well
          statusBarIconBrightness: Brightness.dark, // OR Vice Versa for ThemeMode.dark
          statusBarBrightness: Brightness.light, // OR Vice Versa for ThemeMode.dark
        ),
      ),
     ),

对于那些不使用AppBar的人:

将下面的代码放在根屏幕的构建功能上，以影响下面的所有屏幕:

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

// This widget is the root of your application.
class MyApp extends StatelessWidget {

  /// WORKS on every screen EXCEPT the screen in which appBar is used
  SystemChrome.setSystemUIOverlayStyle(
    SystemUiOverlayStyle(
      // statusBarColor: Colors.red, // You can use this as well
      statusBarIconBrightness: Brightness.dark, // OR Vice Versa for ThemeMode.dark
      statusBarBrightness: Brightness.light, // OR Vice Versa for ThemeMode.dark
    ),
  );
  @override
  Widget build(BuildContext context) {}
}

将下面的代码放在单个屏幕的构建功能上，只影响该屏幕:

class SingleScreen extends StatelessWidget {

  /// WORKS on a single screen where appBar is NOT used
  SystemChrome.setSystemUIOverlayStyle(
    SystemUiOverlayStyle(
      // statusBarColor: Colors.red, // You can use this as well
      statusBarIconBrightness: Brightness.dark, // OR Vice Versa for ThemeMode.dark
      statusBarBrightness: Brightness.light, // OR Vice Versa for ThemeMode.dark
    ),
  );
  @override
  Widget build(BuildContext context) {}
}

@override
Widget build(BuildContext context) {
  return Theme(
    data: ThemeData(brightness: Brightness.dark),
    child: Scaffold()
    ....
  )
}
