connectivity #

This plugin allows Flutter apps to discover network connectivity and configure themselves accordingly. It can distinguish between cellular vs WiFi connection. This plugin works for iOS and Android.

Note that on Android, this does not guarantee connection to Internet. For instance, the app might have wifi access but it might be a VPN or a hotel WiFi with no access.

Usage #

Sample usage to check current status:

import 'package:connectivity/connectivity.dart';

var connectivityResult = await (Connectivity().checkConnectivity());
if (connectivityResult == {
  // I am connected to a mobile network.
} else if (connectivityResult == ConnectivityResult.wifi) {
  // I am connected to a wifi network.

Note that you should not be using the current network status for deciding whether you can reliably make a network connection. Always guard your app code against timeouts and errors that might come from the network layer.

You can also listen for network state changes by subscribing to the stream exposed by connectivity plugin:

import 'package:connectivity/connectivity.dart';

initState() {

  subscription = Connectivity().onConnectivityChanged.listen((ConnectivityResult result) {
    // Got a new connectivity status!

// Be sure to cancel subscription after you are done
dispose() {


You can get wi-fi related information using:

import 'package:connectivity/connectivity.dart';

var wifiBSSID = await (Connectivity().getWifiBSSID());
var wifiIP = await (Connectivity().getWifiIP());network
var wifiName = await (Connectivity().getWifiName());wifi network

iOS 12 #

To use .getWifiBSSID() and .getWifiName() on iOS >= 12, the Access WiFi information capability in XCode must be enabled. Otherwise, both methods will return null.

iOS 13 #

The methods .getWifiBSSID() and .getWifiName() utilize the CNCopyCurrentNetworkInfo function on iOS.

As of iOS 13, Apple announced that these APIs will no longer return valid information. An app linked against iOS 12 or earlier receives pseudo-values such as:

  • SSID: "Wi-Fi" or "WLAN" ("WLAN" will be returned for the China SKU).

  • BSSID: "00:00:00:00:00:00"

An app linked against iOS 13 or later receives null.

The CNCopyCurrentNetworkInfo will work for Apps that:

  • The app uses Core Location, and has the user’s authorization to use location information.

  • The app uses the NEHotspotConfiguration API to configure the current Wi-Fi network.

  • The app has active VPN configurations installed.

If your app falls into the last two categories, it will work as it is. If your app doesn't fall into the last two categories, and you still need to access the wifi information, you should request user's authorization to use location information.

There is a helper method provided in this plugin to request the location authorization: requestLocationServiceAuthorization. To request location authorization, make sure to add the following keys to your Info.plist file, located in <project root>/ios/Runner/Info.plist:

  • NSLocationAlwaysAndWhenInUseUsageDescription - describe why the app needs access to the user’s location information all the time (foreground and background). This is called Privacy - Location Always and When In Use Usage Description in the visual editor.
  • NSLocationWhenInUseUsageDescription - describe why the app needs access to the user’s location information when the app is running in the foreground. This is called Privacy - Location When In Use Usage Description in the visual editor.
