I have here part of my code, hope it's enough.
In short, I want to use the "utilizador" variable value, and insert its text inside a lable, I tried:
Label:
text: utilizador.text
I've been looking for a solution for a long time, I've read everything but I can't solve it. My difficulty is that I have several screens, inside one of them I define a variable.
