How to restart the app by programming?

If I have a restart menu item, or a pop-up box prompts the user to resetart.

import flet as ft
import sys
import os
import time


def restart_program():
    '''
    Restarts the current program.
    Note: this function does not return. Any cleanup action (like saving data) 
    must be done before calling this function.
    '''

    python = sys.executable
    os.execl(python, python, *sys.argv)


def handle_restart(e):
    e.page.window_destroy()

    # todo How to confirm that the application has exited?

    time.sleep(3)
    restart_program()


def main(page: ft.Page):
    btn = ft.ElevatedButton('restart', on_click=handle_restart)
    page.add(btn)


ft.app(target=main)

How to confirm that the application has exited after called page.window_destroy()?

Calling destroy kills the application by closing the window.
Did your app window stay open?

Calling destroy kills the application by closing the window. Did your app window stay open?

If I use python ./demo.py to run the above code, I can restart it, but if I use flet run ./demo.py to run the above code, I cannot restart it. @ndonkoHenri

It would be great if there was a method called page.window_restart()
