New Project but i have Problem

I would like to make an app where you can search something and find it on another screen. how i can do this

Add 2 TinyDB's and use the same namespaces, so you can store that values and read them on another screen.
If you just need one value, use close screen with value, so you don't need TinyDB, store it on a variable on screen.otherscreenclosed event
