firebase config is not generated in Supabase as backend in my particular project

I have my project connected with supabase in Auth and database but want to use push notification from firabase (fcm),

So I connected the firebase and generate config the file with my firebase project but when I see in main.dart file there is no -> "import 'backend/firebase/firebase_config.dart';" and also not present ->"await initFirebase();" and only supabase is present.

Basically I want to save fcm token in my App state that I created but the firebase is not generating file in flutterflow so cann't able to get fcm token.(I have enable permission of push notification)

But main thing is that when I created new FF project and doing same configuration of supabase and firebase then it will work but in my running FF Project it cann't display firebase files so I got the error in local debugging that firebase files are missing.
