You cannot define variables with tinydb get value on initialise. You have to set the variable in an event

I already test it on other project and its working :confused: Here it is I just copied it.

The Tiny db's data is working, Like description, duckname, price, and duck.

Did you fix this:

Yes, Already Fixed it and Now It's not adding and still not adding. No error at all ListView is blank

No warning either :confused: Okay I'm confused now. Screen2(ShippingScreen) blocks still not changed

Start with this, and build on it
