Navbar issues

I have the Navbar enabled for my application, the issue is that I get the following error:

Auth Page Setup
"Page "LandingPage-Teacher" always shows the Nav Bar. This is not possible for the Flutter Default Nav Bar, so you must either undo this or select a different Nav Bar type."

Switching to the Floating Navbar instead of the Default does indeed remove the error from the bug/issues dropdown, but instead prints another Error in Settings>AppDetails>InitialPage "Error: When navbar is enabled, logged in Page must have a Navbar" but the app crashes upon launching in test mode with the following crash report:

Unexpected null value.
The relevant error-causing widget was: NavarPage 
Stack trace: dart: sdk_internal 7421:12

DartError throw_ nullCheck build

To give you some context, the Entry Page of the App is the Login/Register Page.

Any help would be greatly appreciated :) Thanks in advance!
