Flutter网络信息获取插件network_info_plus_tizen的使用

Flutter网络信息获取插件network_info_plus_tizen的使用

_{network_info_plus_tizen 是 Tizen 实现的 network_info_plus 插件。}

要使用该插件，你需要在 pubspec.yaml 文件中同时添加 network_info_plus 和 network_info_plus_tizen 依赖项：

dependencies:
  network_info_plus: ^4.1.0
  network_info_plus_tizen: ^1.1.4

然后，你可以在 Dart 代码中导入 network_info_plus：

import 'package:network_info_plus/network_info_plus.dart';

使用示例

以下是一个完整的示例代码，展示了如何使用 network_info_plus_tizen 插件来获取 Wi-Fi 网络信息。
