Flutter firebase does not initialize

am getting this error.
Unhandled Exception: PlatformException(null-error, Host platform returned null value for non-null return value., null, null)

I have updated all firebase packages in .yaml, i still have this error


E/flutter (11230): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(null-error, Host platform returned null value for non-null return value., null, null)

E/flutter (11230): <asynchronous suspension>

    add these two lines to your main.dart main function

    void main() async{

 WidgetsFlutterBinding.ensureInitialized();
  // initializing the firebase app
  await Firebase.initializeApp();

   
runApp(MyApp());

}

    This is probably caused by the new changes with Firebase CLI with firebase options. So to solve this do add :

    in your terminal

    $ flutterfire configure

    then in your main

    // Import the generated file
import 'firebase_options.dart';

...
await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);
...

    You probably going to be asked to authenticate your firebase account so you’ ll run this in your terminal

    dart pub global activate flutterfire_cli
