Dialog display when starting flet

[gitchin]

No dialog is displayed when flet starts.

import flet as ft

def main(page:ft.Page):
    page.controls = [
        ft.Row(
            controls=[
                ft.Text("Test")
            ]
        )
    ]
    page.update()


    dlg = ft.AlertDialog(
        modal=True,
        content=ft.TextField(label="input")
    )

    page.show_dialog(dlg)

    page.update()


ft.app(target=main)

I don't know why, it was displayed for the first time, but it was not displayed for several times in a row, the chance of recurrence is too small

I happened to make it work.
Add a time delay before showing the dialog:

time.sleep(0.0001)   #any value of your choice
page.show_dialog(dlg)

I don't know the reason for this behaviour. 😕

That's approach I used myself multiple times. I don't like it honestly and I promise it's a temporary solution :)
We need to figure out why is that happening!

I will use time.sleep.
Thank you.
