hi i have a project where im doing a game, and i maked another project for test and if that will work correctly then i will add them, and when i want to export that test project i dont have data from tinydb in game project and is there any way to import screen or change the name of the app or something to have the same tinydb data?
No.
You will need to export the tinydb data to a file, then import that file into your other project, and then populate the tinydb.
