Strange behavior of Refs

[ndonkoHenri]

Refs have a strange behavior. I dont know if this is a bug or its normal/intentional..
I used a ref[textfield] to update a button's text.

from flet import *

def main(page: Page):
    page.title = "Ref Misbehavior"
    page.window_height = 200
    page.window_width = 400

    def click(e):
        # TextField has no property text, but FilledButton.text is successfully updated
        fake_ref.current.text = "Hello France"
        page.update()

    fake_ref = Ref[TextField]()  # changing from Ref[TextField] to Ref[Text] still works

    page.add(
        FilledButton(
            "Hello Estonia",
            fake_ref,
            on_click=click
        )
    )

flet.app(target=main,)

Can someone please explain why this works as such??

using stack or Text instead of textfield still works
surely any control
I expected it to return an error, RefError..
telling me an invalid Ref was used

TextField doesn't have "text" properly, but it has "value".

You maybe didn't understand my question.
So, I have a Button and I passed a Ref[Textfield] to it's ref attribute.
And from there I tried to update the text property of that Button.

The thing is, how/why can Ref[Textfield] be used to update properties of a Button????
fake_ref.current normally has no attribute text, since it's kind of a Textfield, but successfully updated the button.

Because in Python Ref[Textfield] is a generic of type Textfield. It's a type "hint". Python does not enforce types - you can do whatever you like.
