So what happend is: I logged in on the playstore version and then installed a debug apk with flutter run which has overwritten the old one which probably causes the decryption to fail.
We should catch these kind of erros, delete the credentials and show a snackbar that you got logged out

@M123-dev It's a developer's problem, not a real life one. I'm surprised flutter even allowed you to overwrite a version: Android would not mix a Play Store and a dev version and would not install.

[M123-dev]

No really overwriting, it is like a new install but it keeps the app data but removes all references to the playstore etc and since the decryption fails we can see that its still secure, but maybe this also happens in other cases for example when someone migrates all data to a new phone or something so a little check does no harm
