Thanks,

I’m not sure I understand your question, but here is an example of a popup that takes a message at runtime.  I use something similar for errors.

 

from kivy.app import App
from kivy.lang import Builder
from kivy.uix.popup import Popup
from kivy.properties import StringProperty

kv = """
#:import Factory kivy.factory.Factory
<ErrorPopup>:
    title: 'Error'
    BoxLayout:
        orientation: 'vertical'
        Label:
            text: root.error_msg
        Button:
            size_hint_y: None
            height: 48
            text: 'Okay'
            on_release: root.dismiss()

BoxLayout:
    orientation: 'vertical'
    Button:
        text: 'Press Error Popup 1'
        on_release: Factory.ErrorPopup(error_msg='Error Message Number One').open()
    Button:
        text: 'Press Error Popup 2'
        on_release:Factory.ErrorPopup(error_msg='A non-fatal error has occurred').open()
    Button:
        text: 'Press Error Popup 3'
        on_release: Factory.ErrorPopup(error_msg='You lose, your get nothing!').open() 
    Button:
        text: 'Press Error Popup 4, from python'
        on_release: app.error('Oh My, somthing has happened here!')   
"""


class ErrorPopup(Popup):
    error_msg = StringProperty()


class ErrorPopApp(App):
    def build(self):
        return Builder.load_string(kv)

    def error(self, text):
        ErrorPopup(error_msg=text).open()


ErrorPopApp().run()

If you want to instance a popup in kv, use Factory as I did in the example I posted previously.  Note that Factory was imported into kv
