HiveError: The same instance of an HiveObject cannot be stored in two different boxes

I got an issue when I tried to save the same value in (more than one) different boxes.
Here is the hive's output:

[VERBOSE-2:ui_dart_state.cc(199)] Unhandled Exception: HiveError: The same instance of 
an HiveObject cannot be stored in two different boxes.

I really appreciate, it if someone could tell me, how can I save the same object in multiple boxes (by default way of doing that)?
