A simple package to check when the device is connected (connectivity) to internet. Also provide a method to listen for connection status changes.
Include simple_connection_checker
in your pubspec.yaml
file:
dependencies:
flutter:
sdk: flutter
simple_connection_checker: version
To use this package, just import it into your file and call the static method isConnectedToInternet as follows:
import 'package:simple_connection_checker/simple_connection_checker.dart';
...
bool isConnected = await SimpleConnectionChecker.isConnectedToInternet();
...
Note: You can pass an optional parameter named lookUpAddress to pass an especific URL to make the lookup operation and check the internet connection. By default, this value is www.google.com. Do not use the protocol on the URL string passed (http:// or https://).
Now you can listen for internet connection changes. Here is the example
import 'package:simple_connection_checker/simple_connection_checker.dart';
...
StreamSubscription? subscription;
bool? _connected;
@override
void initState() {
super.initState();
SimpleConnectionChecker _simpleConnectionChecker = SimpleConnectionChecker()
..setLookUpAddress('pub.dev'); //Optional method to pass the lookup string
subscription = _simpleConnectionChecker.onConnectionChange.listen((connected) {
setState(() {
_connected = connected;
});
});
}
@override
void dispose() {
subscription?.cancel();
super.dispose();
}
...
Note: Don't forget to cancel the subscription
