Description:

push express lib

Push Express #
Get Started #
This guide will walk you through integrating PushExpressLib into your application and handling push notifications in both foreground and background states.
Import package in your main.dart file
import 'package:push_express_lib/push_express_lib.dart';
copied to clipboard
Then, you can use the package's functions and features in your code.
Guide #
First step #
Initialize package
void initFirebase() async {
// Initialize firebase app
await Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform,
);

// Request permissions for push notifications
await FirebaseMessaging.instance.requestPermission();

// get unique token for messaging from firebase messaging
String? token = await FirebaseMessaging.instance.getToken();

if (token != null) {
// initialize package
PushExpressManager().init(
// your application id from https://app.push.express/
'21486-1212',
TransportType.fcmData,
transportToken: token,
// set property foreground "true" if you need to get notifications when app is in foreground (IOS only)
foreground: true,
);
}
}

@override
void initState() {
super.initState();

// call to init
initFirebase();
}

Second step #
Enable Background messaging
Future<void> firebaseMessagingBackgroundHandler(RemoteMessage message) async {
// initialize firebase app
await Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform,
);

// call function from the package to handle notifications,
// and show them properly in background
NotificationManager().handleNotification(message);
}

void main() {
// ensure widgets are initialized
WidgetsFlutterBinding.ensureInitialized();

// handle Firebase background messages
// and call our handler
FirebaseMessaging.onBackgroundMessage(firebaseMessagingBackgroundHandler);

runApp(const MyApp());
}

Third step (OPTIONAL) #
// If you want to get any push notification in foreground
// add this lines to your code
FirebaseMessaging.onMessage.listen(
// provide this function to handle notifications and show them properly
NotificationManager().handleNotification,
);
