Flet App close error

[hikmetalemdaroglu]

'Flet' app window gives the following error when closed with the cross sign.

Here is sample code:

import flet as ft

def main(page: ft.Page):

add/update controls on Page

# pass
t = ft.Text(value="Hello, world!", color="green")
page.controls.append(t)
page.update()
btn = ft.ElevatedButton("Click me!")
page.add(btn)

ft.app(target=main)

ft.app(target=main, view=ft.AppView.WEB_BROWSER)

---

And here is the error :

%Run flet-002_counter.py
