page.dialog is not working

[Pranzal360]

I was working with this file and i tried to run it in my system, when ever the website load, the dialog box doesn't appears.
but it works after the second execution.

Let me make it simple for you to understand
let me start with:
i run the code and it opens in the browser but the dialog box doesn't appears, now i don't close the tab where it is opened and now i stop the code and run it again, this time too it opens in another tab, this time too dialog box doesn't appears on the second tab but it opens in the previously opened tab.

the tab on first image was opened during second execution where page.dialog doesn't opens
the tab on the second image was opened during first execution where initially page.dialog didn't open but after second execution (without closing the tab ) page.dialog opened.

Hey, I'm a little late on this, but has anyone figured out what the problem was?
I'm currently encountering the same issue!

UPDATE: I found my issue. I'm no longer sure if I had the same one...

My problem (from my understanding) was that I initialized my page wrong. I added an AlertDialog to the page without adding something else. Then I switched with the router to another page.view component. And tried to show another dialog with page.show_diaog(dialog)

wrong code:

def main(page: ft.Page) -> None:
    """
    Entry point of application
    """ 
     
    page.title = "Notes App"
    page.adaptive = True
    
    if not page.client_storage.contains_key(StorageKeys.BASE_PATH.value): 
        alert_set_path: ft.AlertDialog = AlertDialogSetBasePath(page=page).build()
        page.add(alert_set_path)
        page.show_dialog(alert_set_path)
    
    while True:

SOLUTION:

1. Initialize your page better ;)
2. Quick and dirty: use page.clean() or page.controls.clean after you no longer need the dialog
