How to get the wifi name(SSID) of the currently connected wifi in Flutter

Question

With the help of this Connectivity Plugin, I am able to get the connection status i.e. mobile network, wifi or none using the following code:

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')),
    );
  }
}

Now what I want is to get the name of the Wifi when the phone is connected to wifi. Detailed Description: Suppose the user has connected his/her phone with a wifi named "Home Wifi", from the code I have wriiten I am only able to get if the phone is connected to wifi or not, I also want to get the name of the wifi if the phone is connected to the wifi i.e. "Home Wifi".

Solution

It's just calling getWifiName(), available in the wifi_info_flutter plugin. This method used to be available in the connectivity plugin, but it has been moved to this new plugin by the end of 2020.

In iOS, using this solution requires the steps described in this answer.

You can also use the GIT url directly in a pubspec.yaml.

Thanks a lot. It's working fine. I have only checked for android device for now. I hope this works fine on ios too.

[Sarthak Verma]

I would also love to know how can I add the git url directly as Randal mentioned.

[Feu]

Ah, here's how to add directly from git as @RandalSchwartz mentioned. I saw it once but totally forgot. You would have to use git: url: [email protected]:flutter/plugins.git and path: packages/connectivity.

So I've gotten this to work in android, but in ios i'm getting an exception PlatformException(UNAVAILABLE, wifi name unavailable, null). Permission problem?

[Feu]

@Rob C, Yes, I think it deserves a new question! :)

[Rob C]

Done, thanks for the suggestion. For reference: stackoverflow.com/questions/55716751/…

I always receive <unknown ssid> when I called getWifiName.

[Feu]

@Dhaval Kansara, is it iOS? Did you check stackoverflow.com/a/55732656/796963 ?

[Dhaval Kansara]

@Feu Yes, I have already added Access Wifi Information for my project.

[Bawantha]

The BSSID may be null, if there is no network currently connected. "02:00:00:00:00:00", if the caller has insufficient permissions to access the BSSID. found this from android developer site but don't know how to add permissons

@Feu I am also using connectivity plugin to get wifi ssid for IOS with the method connectivity.getWifiName(), but it returns null, but I can get IP with getWifiIP() method. What could be the problem?

[Imranrana07]

@Feu this is my attempt stackoverflow.com/questions/63857789/…

This is no longer null safe
