+# connectivity
+
+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:
+
+```dart
+import 'package:connectivity/connectivity.dart' as connectivity;
+
+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.
+}
+```
+
+## Getting Started
+
+For help getting started with Flutter, view our online
+[documentation](http://flutter.io/).
+
+For help on editing plugin code, view the [documentation](https://flutter.io/platform-plugins/#edit-code).
