initConnectivity method
initialize connectivity checking Platform messages are asynchronous, so we initialize in an async method.
Implementation
Future<void> initConnectivity() async {
try {
await _connectivity.checkConnectivity();
} on PlatformException catch (e) {
print(e.toString());
}
// If the widget was removed from the tree while the asynchronous platform
// message was in flight, we want to discard the reply rather than calling
// setState to update our non-existent appearance.
if (!mounted) {
return;
}
await _updateConnectionStatus().then((bool isConnected) => setState(() {
isOnline = isConnected;
}));
}
