I second @zigapovhe and don’t think that this issue should be closed.

Same issue on Google Pixel 3XL, Android 12.

I have encountered this error when someone tried to migrate to the new encrypted method for android. See https://github.com/mogol/flutter_secure_storage/issues/313

I have a few other plugins that require some attention so i don’t have the time to look in to this right now. It would be great if some could debug this and check what the problem can be. I will check all PR’s asap.

this an android jetpack crypto lib “problem” (it’s just a debug message…) so not related to this plugin and nothing they can do about it

Well, this is not the case in 4.2.1 version of flutter_secure_storage plugin. At least what @mogol can do is downgrade the crypto library to the same version as it was in v4.2.1. If this is really just a “debug message”, something else is going on in flutter_secure_storage, because the plugin never initialize after this error occur (can be replicated by clearing app storage). I wouldn’t close the issue if people still experience the same issue on latest version (6.0.0). @juliansteenbakker
