Reset all information from firebase

Can someone help me? I already searched but found nothing. I created the whole structure with firebase and it communicates well, I can create, update and delete 1 label. but i wanted to delete everything at once from firebase as in the same way you delete everything from tinydb. but I don’t know how to set up the structure for that. can anybody help me? thanks in advance

Be more specific + show blocks of what you already tried.

that’s the problem. I don’t know how to assemble the blocks to create this function of general erasing the bucket from the project. the print I send here I know is not correct, but unfortunately it is what I managed to do.

You can use clear tag block of firebase to delete data of your firebase database from your app or you can make an admin app for that to do it from your phone or you can manually delete from firebase site.
