[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Null check operator used on a null value
E/flutter (25200): #0      _ItemsUploadScreenState.saveInfo (package:sellers_food_app/upload_screens/items_upload_screen.dart:458:26)

E/flutter (25200): <asynchronous suspension>

when saving it's stuck in a loop and no info is saved to the storage can any one help?

I thought it was the save function or the validation i tried them then an error no app check token found i set it up by adding the dependencies and the code and now it shows..

Error getting App Check token; using placeholder token instead.
Error: com.google.firebase.FirebaseException: No AppCheckProvider installed.

but I don't think it's the app check
