Input Firebase App can not be nil

[nominator]

Hi,

I am getting this error when trying to use MLKit plugin. Rest of flutterfire plugins are working.
There was another error I was getting
__FIRAPP_DEFAULT does not exist

This was solved by making following changes to AppDelegate.m

import UIKit
import Flutter
import Firebase

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
FirebaseApp.configure()
GeneratedPluginRegistrant.register(with: self)
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
}

But still I am getting the error mentioned in the topic. Please help!!

Thanks
