network_handler

Description:

network handler

network_handler #
Notifies your app whenever your device's network connection status changes. It exposes a callback for you to handle those changes.

Usage #
// ...
import 'package:network_handler/network_handler.dart';
import 'package:network_handler/network_status.dart';

class SomeWidget extends StatefulWidget {
@override
_SomeWidgetState createState() => _SomeWidgetState();
}

class _SomeWidgetState extends State<SomeWidget> {
@override
Widget build(BuildContext context) {
return NetworkHandler(
onChanged: (NetworkStatus status) {
// Handle network status changes here
if (status == NetworkStatus.connected) {
// ...

} else if (status == NetworkStatus.disconnected) {
// ...

} else {
// ...
}
},
child: WrappedWidget()
);
}
}

How does it work? #
Once NetworkHandler is added to your widget tree, it pings a host (example.com by default) every x milliseconds (2000 by default) and determines whether the connection was successful.
This process is executed on a separate event loop, using an Isolate. No external libraries were used, only native Dart/Flutter modules.
Known issues and limitations #

This package assumes that the host will always be online.
Cannot pause/resume network status checks.
A refreshTimer parameter can be provided to NetworkHandler, however it is currently being ignored.
NetworkHandler does not discern between different types of network connection, e.g. Wi-Fi and mobile data. This behaviour is intentional for simplicity. I suggest looking into connectivity for this purpose.
