🐛 [firebase_core] Allow app initialization without credentials about flutterfire

@fcoelho - thank you for the suggestion but this would be something of a major refactor for FlutterFire which isn't necessary. The client side credentials are not sensitive and there is no problem with using them.

@russellwheatley that's okay and thanks for the info. I don't know how I can get client-side credentials for this though since I can't use FirebaseAuth.instance before the app is initialised. Could you point me to some documentation I can read on this?

All client side credentials are available on the Firebase console:

Here is documentation

You can also use FlutterFire CLI to configure your Firebase app on Flutter.
