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.

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() {

  • Support for TYPE_MOBILE_HIPRI on Android.

0.4.3+2 #

  • Add missing template type parameter to invokeMethod calls.

0.4.3+1 #

  • Fixes lint error by using getApplicationContext() when accessing the Wifi Service.

0.4.3 #

  • Add getWifiBSSID to obtain current wifi network's BSSID.

0.4.2+2 #

  • Add integration test.

0.4.2+1 #

  • Bump the minimum Flutter version to 1.2.0.
  • Add template type parameter to invokeMethod calls.

0.4.2 #

  • Adding getWifiIP() to obtain current wifi network's IP.

0.4.1 #

  • Add unit tests.

0.4.0+2 #

  • Log a more detailed warning at build time about the previous AndroidX migration.

0.4.0+1 #

  • Updated Connectivity to a singleton.

0.4.0 #

  • Breaking change. Migrate from the deprecated original Android Support Library to AndroidX. This shouldn't result in any functional changes, but it requires any Android apps using this plugin to also migrate if they're using the original support library.

0.3.2 #

  • Adding getWifiName() to obtain current wifi network's SSID.

0.3.1 #

  • Updated Gradle tooling to match Android Studio 3.1.2.

0.3.0 #

  • Breaking change. Set SDK constraints to match the Flutter beta release.

0.2.1 #

  • Fixed warnings from the Dart 2.0 analyzer.
  • Simplified and upgraded Android project template to Android SDK 27.
  • Updated package description.

0.2.0 #

  • Breaking change. Upgraded to Gradle 4.1 and Android Studio Gradle plugin 3.0.1. Older Flutter projects need to upgrade their Gradle setup as well in order to use this version of the plugin. Instructions can be found here.

0.1.1 #

  • Add FLT prefix to iOS types.

0.1.0 #

  • Breaking API change: Have a Connectivity class instead of a top level function
  • Introduce ability to listen for network state changes

0.0.1 #

  • Initial release
