Flutter网络信息获取插件network_info_plus_ohos的使用

Flutter网络信息获取插件network_info_plus_ohos的使用

network_info_plus_ohos 是一个用于在 OpenHarmony 平台上获取网络信息（如WiFi详情）的Flutter插件。它是 network_info_plus 在 OpenHarmony 平台上的实现。

使用步骤

1. 添加依赖

   在你的项目的 pubspec.yaml 文件中添加以下依赖项：

   dependencies:
     network_info_plus: any
     network_info_plus_ohos: any
   

2. 请求权限

   在你的项目的 module.json5 文件中增加以下权限设置：

   requestPermissions: [
     {"name" :  "ohos.permission.INTERNET"},
     {"name" :  "ohos.permission.GET_WIFI_INFO"},
   ],
   

3. 编写代码

   下面是一个完整的示例代码，展示了如何使用 network_info_plus_ohos 插件来获取WiFi相关信息。
