• Add firebase_messaging as a dependency in your pubspec.yaml file.

• Perform Android integration for firebase_messaging plugin.

• Import necessary dependencies into main.dart.

import 'dart:async';
import 'package:firebase_messaging/firebase_messaging.dart';

• Instantiate firebase messaging to access the API methods such as getToken() etc.

final FirebaseMessaging _firebaseMessaging = FirebaseMessaging();

• Obtain a registration token that uniquely identifies the app instance by adding _firebaseMessaging.getToken() inside initState() of main.dart to ensure it's only obtained once when the app launches; save it in fcm_token variable.
