Hi,
I am using FlutterFlow but with a custom backend and wasn't intending to use Firebase at all. However it seems all documentation on push notifications with Flutterflow (and even with Flutter?) starts with Firebase.
Is Firebase mandatory for push notifications for a mobile app built with FF?
If so could you please point me towards documentation that explains how it can be integrated with a backend outside Firebase?
Any relevant information or documentation is welcome!
Thank you!
