Hi @sumanthkumarps
Please follow iOS Integration
Also add

import UIKit
import Flutter
import Firebase

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    if #available(iOS 10.0, *) {
      UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
    }
    FirebaseApp.configure()
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

Please execute following from root of your ios folder and alsoe make sure you've firebase in your. AppDelegate
pod init
pod install
pod update
and try again

Can you please provide your flutter doctor -v your flutter run --verbose and a complete reproducible minimal code sample
Thank you

Is it mandatory to implement IOS integration for Android?

Hi @sumanthkumarps
It's my bad, i thought this was iOS, must have confused another issue with this one

Please follow Android Integration

and if you'r using kotlin this in your MainActivity class and also enable Multidex AndroidX Migration

import android.os.Bundle
import io.flutter.embedding.android.FlutterActivity
import io.flutter.plugin.common.PluginRegistry
import io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin
import io.flutter.plugins.firebasemessaging.FlutterFirebaseMessagingService
import io.flutter.view.FlutterMain

class MainActivity : FlutterActivity(), PluginRegistry.PluginRegistrantCallback {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        FlutterFirebaseMessagingService.setPluginRegistrant(this);
        FlutterMain.startInitialization(this)
    }

    override fun registerWith(registry: PluginRegistry?) {
        if (!registry!!.hasPlugin("io.flutter.plugins.firebasemessaging")) {
            FirebaseMessagingPlugin.registerWith(registry!!.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin"));
        }
    }

}

Thank you
