如何在Flutter中获取当前连接的wifi的wifi名称（SSID）

Question

借助此 Connectivity Plugin，我可以使用以下代码获取连接状态，即移动网络、wifi 或 none：

import 'dart:async';

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:connectivity/connectivity.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'Flutter Demo',
      theme: new ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: new MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  final String title;

  @override
  _MyHomePageState createState() => new _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  String _connectionStatus = 'Unknown';
  final Connectivity _connectivity = new Connectivity();
  StreamSubscription<ConnectivityResult> _connectivitySubscription;

  @override
  void initState() {
    super.initState();
    initConnectivity();
    _connectivitySubscription =
        _connectivity.onConnectivityChanged.listen((ConnectivityResult result) {
      setState(() => _connectionStatus = result.toString());
    });
  }

  @override
  void dispose() {
    _connectivitySubscription.cancel();
    super.dispose();
  }


  Future<Null> initConnectivity() async {
    String connectionStatus;

    try {
      connectionStatus = (await _connectivity.checkConnectivity()).toString();
    } on PlatformException catch (e) {
      print(e.toString());
      connectionStatus = 'Failed to get connectivity.';
    }


    if (!mounted) {
      return;
    }

    setState(() {
      _connectionStatus = connectionStatus;
    });
  }

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(
        title: const Text('Plugin example app'),
      ),
      body: new Center(
          child: new Text('Connection Status: $_connectionStatus\n')),
    );
  }
}

现在我想要的是当phone连接到wifi时获取Wifi的名称。详细描述：假设用户已经连接 his/her phone 和一个名为 "Home Wifi" 的 wifi，从我写的代码中我只能在 phone 连接到wifi 与否，如果 phone 连接到 wifi，我还想获取 wifi 的名称，即 "Home Wifi"。

Answer 1

只是调用了getWifiName(), available in the wifi_info_flutter plugin. This method used to be available in the connectivity插件，2020年底已经转移到这个新插件上了

在 iOS 中，使用此解决方案需要步骤。

Answer 2

2022 年，我切换到 network_info_plus 库，就我而言，这个新版本比旧版本好。它仍然使用与旧版本相同的方法名称来获取wifi的名称：getWifiName().
