How to delete database when run test?

**Question**
I run the test and save an object in a box, then i changed HiveField index and mess it up a little bit.
When i run again i keep getting `...is not a subtype of...`

How can i delete all database. I tried `flutter clean` `flutter pub cache repair` `invalidate cache and restart` `flutter pub upgrade` but no use

The report mentions a HiveField index change and Flutter cleanup commands, but names no files or tests. Start by identifying where the test database is stored and how Hive schema changes are handled; done means rerunning the test without the subtype error after clearing or migrating the persisted data.
