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.

Your posted code is not a minimal reproducible example, but here is an example of one way to do what you want:

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.
Your posted code is not a minimal reproducible example, but here is an example of one way to do what you want:
from kivy.app import App
from kivy.lang import Builder
from kivy.uix.screenmanager import ScreenManager, Screen
class WindowManager(ScreenManager):
pass
class ScreenLogin(Screen):
pass
class ScreenPaginaInicial(Screen):
pass
kv = '''
WindowManager:
ScreenLogin:
id: ScreenLogin
ScreenPaginaInicial:
id: ScreenPaginaInicial
<ScreenLogin>:
name: 'ScreenLogin'
BoxLayout:
TextInput:
id: utilizador
on_text: root.manager.ids.ScreenPaginaInicial.ids.lab.text=self.text # update Label whenever text changes
Button:
text: 'other Screen'
on_release: root.manager.current='ScreenPaginaInicial'
<ScreenPaginaInicial>:
name: 'ScreenPaginaInicial'
BoxLayout:
Label:
id: lab
text: 'Abba'
Button:
text: 'other Screen'
on_release: root.manager.current='ScreenLogin'
'''
class TestApp(App):
def build(self):
return Builder.load_string(kv)
TestApp().run()
