Flutter plugin for discovering the state of the network (WiFi & mobile/cellular) connectivity on Android and iOS.

connectivity #


Deprecation Notice #

This plugin has been replaced by the Flutter Community Plus Plugins version, connectivity_plus. No further updates are planned to this plugin, and we encourage all users to migrate to the Plus version.

Critical fixes (e.g., for any security incidents) will be provided through the end of 2021, at which point this package will be marked as discontinued.


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 == ConnectivityResult.mobile) {
  // 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';

@override
initState() {
  super.initState();

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

// Be sure to cancel subscription after you are done
@override
dispose() {
  super.dispose();

  subscription.cancel();
}

Note that connectivity changes are no longer communicated to Android apps in the background starting with Android O. You should always check for connectivity status when your app is resumed. The broadcast is only useful when your application is in the foreground.
