Flutter获取IP适配器信息插件flutter_ip_adapter_info的使用

Flutter获取IP适配器信息插件flutter_ip_adapter_info的使用

flutter_ip_adapter_info 是一个用于在 Windows 上获取 IP_ADAPTER_INFO 的 Flutter 插件。

使用方法

首先，确保你的项目已经添加了 flutter_ip_adapter_info 依赖。你可以在 pubspec.yaml 文件中添加以下依赖：

dependencies:
  flutter_ip_adapter_info: ^版本号

然后运行 flutter pub get 来获取依赖。

以下是使用 flutter_ip_adapter_info 获取 IP 适配器信息的示例代码：

import 'package:flutter/material.dart';
import 'package:flutter_ip_adapter_info/flutter_ip_adapter_info.dart';

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

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  List<IpAdapterInfo> adapterInfoList = [];

  [@override](/user/override)
  void initState() {
    super.initState();
    // 在初始化时获取 IP 适配器信息
    getIpAdapterInfo();
  }

  Future<List<IpAdapterInfo>> getIpAdapterInfo() async {
    final List<IpAdapterInfo> adapterInfoList =
        await FlutterIpAdapterInfo.getIpAdapterInfo();
    setState(() {
      this.adapterInfoList = adapterInfoList;
    });
    return adapterInfoList;
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('flutter_ip_adapter_info 示例应用'),
        ),
        body: ListView.builder(
          itemBuilder: (context, index) {
            return Card(
              child: ListTile(
                title: Text('适配器名称: ${adapterInfoList[index].adapterName}'),
                subtitle: Text('描述: ${adapterInfoList[index].description}'),
                trailing: Text('MAC 地址: ${adapterInfoList[index].macAddress}'),
              ),
            );
          },
          itemCount: adapterInfoList.length,
        ),
        floatingActionButton: FloatingActionButton(
          child: const Icon(Icons.refresh),
          onPressed: () async {
            final List<IpAdapterInfo> newAdapterInfoList =
                await FlutterIpAdapterInfo.getIpAdapterInfo();
            setState(() {
              adapterInfoList = newAdapterInfoList;
            });
          },
        ),
      ),
    );
  }
}

示例代码解释

1. 导入必要的包：

   import 'package:flutter/material.dart';
   import 'package:flutter_ip_adapter_info/flutter_ip_adapter_info.dart';
   

2. 创建主应用类：

   class MyApp extends StatefulWidget {
     const MyApp({Key? key}) : super(key: key);
   
     [@override](/user/override)
     State<MyApp> createState() => _MyAppState();
   }
   

3. 定义状态管理类：

   class _MyAppState extends State<MyApp> {
     List<IpAdapterInfo> adapterInfoList = [];
   
     [@override](/user/override)
     void initState() {
       super.initState();
       getIpAdapterInfo();
     }
   

4. 获取 IP 适配器信息的方法：

   Future<List<IpAdapterInfo>> getIpAdapterInfo() async {
     final List<IpAdapterInfo> adapterInfoList =
         await FlutterIpAdapterInfo.getIpAdapterInfo();
     setState(() {
       this.adapterInfoList = adapterInfoList;
     });
     return adapterInfoList;
   }
   

5. 构建 UI：

   [@override](/user/override)
   Widget build(BuildContext context) {
     return MaterialApp(
       home: Scaffold(
         appBar: AppBar(
           title: const Text('flutter_ip_adapter_info 示例应用'),
         ),
         body: ListView.builder(
           itemBuilder: (context, index) {
             return Card(
               child: ListTile(
                 title: Text('适配器名称: ${adapterInfoList[index].adapterName}'),
                 subtitle: Text('描述: ${adapterInfoList[index].description}'),
                 trailing: Text('MAC 地址: ${adapterInfoList[index].macAddress}'),
               ),
             );
           },
           itemCount: adapterInfoList.length,
         ),
         floatingActionButton: FloatingActionButton(
           child: const Icon(Icons.refresh),
           onPressed: () async {
             final List<IpAdapterInfo> newAdapterInfoList =
                 await FlutterIpAdapterInfo.getIpAdapterInfo();
             setState(() {
               adapterInfoList = newAdapterInfoList;
             });
           },
         ),
       ),
     );
   }
