[Auth Migration] Native Session Not Detected After Upgrading to Flutter

[ala-harri]

Description

When migrating our existing production apps from Native Android/iOS to the new Flutter implementation, the current logged-in session is not being migrated or preserved. As a result, users who update to the Flutter build are forced to log in again instead of continuing seamlessly with their existing authenticated state.

@ala-harri This not a feature that we have supported. I am gonna mark this as a feature request and at the same time work with my team to investigate if we are able to provide any workaround where you can retain the sessions after an upgrade from iOS/Android to Flutter.
