Tinydb and firebase db??

[SteveJG]

TinyDB works like this> TinyDB

FirebaseDB works like this FirebaseDB

How YOU retrieve from the TinyDB depends on how YOU save to it (TinyDB.StoreValue) .

Did you save the state of the AutoSave.CheckBox to the TinyDB? The saved state will be either true or false depending on whether checked or not checked.

Possibly you want to connect AutoSave.Checked to the TinyDB1.GetValue ? which should be true or false.

I'm trying to make so when i check tinyDB and reopen the app its still saved, but it doesnt work whatever i try

@domen_nedelko

but it doesnt work

Your TinyDB GetValue block will not do anything, it must be inside for example an event

Therefore in your Screen Initialize event do it like this

Set Autosave.Checked to TinyDB.GetValue...
Also the socket valueIffTagNotThere should be a boolean value true or false
