Problem running APP in test and run mode

When trying to run the APP, I have the following error

Launching lib/main.dart on Web Server in debug mode...
Waiting for connection from debug service on Web Server...
lib/main.dart:191:17: Error: The getter 'entryPage' isn't defined for the class '_MyAppState'.
- '_MyAppState' is from 'package:wellness_watcher_a_p_p/main.dart' ('lib/main.dart').
Try correcting the name to the name of an existing getter, or defining a getter or field named 'entryPage'.
? entryPage ?? NavBarPage()
^^^^^^^^^
Waiting for connection from debug service on Web Server...         63.7s
Failed to compile application.

I have tried downloading the APK to an Android phone and it also fails.

I have tried using a snapshot form a few day ago (when it was working for me) and I get the same error, so I assume that the error comes from some configuration that does not change with the snapshot. Could this be?

I can't figure out where this comes from, my 'entryPage' define in the "Settings --> App Details --> Entry Page" is set to "Login" which is a page that exists.

Any idea where this could come from, or where to look for the issue?

Thank you very much in advance!

Editing just to add that I tried it out locally (pushing the code and running it locally), and I only had to add that requested getter, so I assume that this is an error on the FlutterFlow side.
