🔨 Usage
This package contains a FcmTokenSync widget, which you can wrap around any widget in your project.

Example
class HomePage extends StatelessWidget {
const HomePage({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return FcmTokenSync(
firebaseMessaging: FirebaseMessaging.instance,
onToken: _updateFcmToken,
child: Scaffold(), // Widget to display here
);
}
Future<void> _updateFcmToken(String token) async {
// Send the updated token to your backend here.
}
}
