This plugin allows Flutter apps to discover network connectivity and configure themselves accordingly. It can distinguish between cellular vs wifi connection.

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:

import 'package:connectivity/connectivity.dart' as connectivity;

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.
