I have a flutter app for mobile and I am porting it to web. I have implemented the Go Router package. I have singleton classes in my code which save the login info so that I can access them later on dashboard etc. The chrome refresh works fine on login screen but after login on dashboard I get the red screen with unexpected null value text.

The following TypeErrorImpl was thrown building Builder:
Unexpected null value.

The relevant error-causing widget was:
  Navigator-[LabeledGlobalKey<NavigatorState>#6e84c]
  Navigator:file:///Users/ichi14/.pub-cache/hosted/pub.dev/go_router-14.2.1/lib/src/builder.dart:429:16

Do i need to use some local cache for this login info? on refresh singletons get destroyed?
How can I keep these profile information accessible through the app?

login_info is a complete model class kept in the singleton
