在flutter中判断平台，获取设备信息

发布时间：2019-07-13 发布网站：脚本宝典

脚本宝典收集整理的这篇文章主要介绍了在flutter中判断平台，获取设备信息，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。

在生产环境app的开发过程中，获取设备信息是必不可少的一步，本文详细介绍在flutter中如何判断平台是android还是ios，并使用开源库device_info获取andROId和ios的设备信息。
判断平台
这步很简单，导入平台Platform库就行，位置在dart:io

      
      
      
      
      
import 'dart:io';
然后在android studio中编辑的时候就有快捷菜单了:

判断平台只要使用如下代码：

      
      
      
      
      
    if(Platform.isIOS){
      //ios相关代码
    }else if(Platform.isAndroid){
      //android相关代码
    }
device_info库的使用
先上图


1、添加依赖
在PubsPEc.yML中的dependencies下面新增节点

      
      
      
      
      
  device_info : ^0.2.0
上图比较快：

然后点下编辑器的"Packages get"或者运行命令行：

      
      
      
      
      
flutter packages get
注意这里可能需要配置环境变量:

      
      
      @H_571_126@
      
      
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
@H_777_142@2、获取信息

好吧，只要一行依赖就可以集成两个平台的项目代码，毫无繁琐配置，flutter真的简单。
