Using self.page to check if a control is added to page?

[jnsh]

Question

I just discovered that Flet controls have a page property, that contains the ft.Page the control is added to, or None if it is not on any page.

So for example you could do something like this, to avoid AssertionErrors in certain situations:

if self.page:
    self.update()

Overall, being able to easily access the page is extremely useful.

My concern is, I could not find this documented anywhere, so I'm not sure if it is a feature, or just something part of the architecture of Flet that should not be used any real code, or something that could be removed in the future.

So the question is: is it OK to use self.page in your production code, or not?

Yes, you can check self.page to know if control instance has been added to a page.

Excellent! It will be super handy.
Thank you for the clarification!
