Relacionate two text of differents screens (Interact text of two differents screens)

Hello, I am a young guy who have a problem to create his app. I want to relacionate one TextBox to another TextBox in another screen. Please can you help me???

TextBox1 (this from screen1) = TextBox2 (from screen2)

Would like help me please??

This is not possible. Just create the textbox again in the other screen.

Or did you want to transfer the content? In that case you can either open another screen with a start value, or transfer the value via a TinyDB.
