flutter - 如何在Flutter中获取当前连接的wifi的wifi名称(SSID)

Question

借助这个Connectivity Plugin ，我可以使用以下代码获取连接状态，即移动网络、wifi 或无:

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')),
    );
  }
}

现在我想要的是当手机连接到wifi时获取Wifi的名称。详细描述:假设用户已经将他/她的手机连接到一个名为“Home Wifi”的wifi，从我写的代码中我只能知道手机是否连接到wifi，我也想得到这个名字如果手机连接到 wifi，即“家庭 Wifi”。

它只是调用getWifiName() , 在 network_info_plus 中可用插入。此方法曾经在 connectivity 中可用插件，但后来已移至此新插件。

在 iOS 中，使用此解决方案需要以下步骤 described in this answer .
