Flutter FCM problem: notification not appearing - flutter

Question

I'm trying to use Firebase Cloud Messaging to set up push notifications for my app. I'm trying to start of simple by manually sending a notification payload and have it handled as a background notification in the android app. However, no notification appears in the emulator.
This is my current main.dart code:
import 'package:flutter/material.dart';
import 'package:redue/Screens/Welcome%20Screen/WelcomeScreen.dart';
import 'pages/menu.dart';
import 'package:firebase_core/firebase_core.dart';
import 'firebase_options.dart';
import 'pages/settings.dart';
import 'package:location/location.dart';
import 'pages/settings.dart';
import 'package:firebase_messaging/firebase_messaging.dart';
Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
await Firebase.initializeApp();
print("Handling a background message: ${message.messageId}");
}
final FirebaseMessaging _firebaseMessaging = FirebaseMessaging.instance;
Future main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);
Location location = new Location();
bool _serviceEnabled;
PermissionStatus _permissionGranted;
_serviceEnabled = await location.serviceEnabled();
if (!_serviceEnabled) {
_serviceEnabled = await location.requestService();
if (!_serviceEnabled) {
return null;
}
}
_permissionGranted = await location.hasPermission();
if (_permissionGranted == PermissionStatus.denied) {
_permissionGranted = await location.requestPermission();
if (_permissionGranted != PermissionStatus.granted) {
return null;
}
}
_firebaseMessaging.requestPermission(
alert: true,
announcement: false,
badge: true,
carPlay: false,
criticalAlert: false,
provisional: false,
sound: true,
);
FirebaseMessaging messaging = FirebaseMessaging.instance;
FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);
FirebaseMessaging.onMessage.listen((RemoteMessage message) {
print('Got a message whilst in the foreground!');
print('Message data: ${message.data}');
if (message.notification != null) {
print('Message also contained a notification: ${message.notification}');
}
});
runApp(const MyApp());
}
class MyApp extends StatefulWidget {
const MyApp({super.key});
#override
State<MyApp> createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
// This widget is the root of your application.
#override
void initState() {
super.initState();
currentTheme.addListener(() {
setState(() {});
});
}
#override
Widget build(BuildContext context) {
return MaterialApp(
title: "ReDue",
debugShowCheckedModeBanner: false,
theme: ThemeData.light(),
darkTheme: ThemeData.dark(),
home: WelcomeScreen(),
);
}
}
I'm also using cloud firestore in my app as well as google services (why I ask for the location). I should also note that when I open the app in the emulator I have not recieved a notification permission method and in the firebase console when I publish the notification it says the notification has zero sends.
