我是靠谱客的博主健康外套，最近开发中收集的这篇文章主要介绍Android设置状态栏颜色，沉浸式状态栏 fllutter Android设置沉浸式状态栏，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1. Android原生设置沉浸式状态栏，设置状态栏颜色，字体颜色

flutter Android 设置沉浸式窗台兰，在flutter项目lib下的main方法下加如下代码，在runApp之后加


//设置状态栏沉浸式（修改flutter状态栏黑色半透明为全透明）
if (defaultTargetPlatform == TargetPlatform.android) {
SystemUiOverlayStyle systemUiOverlayStyle = SystemUiOverlayStyle(
statusBarColor: Colors.blue,//该颜色也可以设置成透明或者半透明
statusBarBrightness: Brightness.dark,
);
SystemChrome.setSystemUIOverlayStyle(systemUiOverlayStyle);
}
