Has anyone ever experienced this? I will try to get an MVCE but i wanted to throw it out here before i forget because this is where "Get help" from the documentation went. :)

from pubspec.lock

mac app uses Timer() to have db access every x minutes iOS app uses https://pub.dev/packages/flutter_background_geolocation for db access when location changes.

I did a test project and this happened to me the other way. I opened an encrypted box and stored some values, then next time I opened the box without encryption and when I check the box.values they are empty.

Is this expected in any way? I was expecting that I could check whether the db is encrypted by getting some garbage data. Even if I open the box with encryption again, it is always empty after first time.

We worked with this a long long time because of iOS and Flutter secure storage

Hive should have better documentation around this and throw an exception rather than corrupt/delete data IMHO but I guess they just consider it your responsibility to use the right key. Your use case sounds a little different but similar. I suspect it is expected behavior. There probably isn't any way to know if the box is encrypted any more than knowing if you have the right key

I mean unless of course you know the filename and put the file in a string. It's "just" a file right?
