[Question] Flet AlertDialog

[7576457]

Question

I ran this code from the documentation in the flet application from the appstore, and I get this bug or error. What is the reason for this and how to fix it?

Code sample

import flet as ft

def main(page: ft.Page):
    page.title = "AlertDialog examples"

    dlg = ft.AlertDialog(
        title=ft.Text("Hello, you!"), on_dismiss=lambda e: print("Dialog dismissed!")
    )

    def close_dlg(e):
        dlg_modal.open = False
        page.update()

    dlg_modal = ft.AlertDialog(
        modal=True,
        title=ft.Text("Please confirm"),
        content=ft.Text("Do you really want to delete all those files?"),
        actions=[
            ft.TextButton("Yes", on_click=close_dlg),
            ft.TextButton("No", on_click=close_dlg),
        ],
        actions_alignment=ft.MainAxisAlignment.END,
        on_dismiss=lambda e: print("Modal dialog dismissed!"),
    )

    def open_dlg(e):
        page.dialog = dlg
        dlg.open = True
        page.update()

    def open_dlg_modal(e):
        page.dialog = dlg_modal
        dlg_modal.open = True
        page.update()

    page.add(
        ft.ElevatedButton("Open dialog", on_click=open_dlg),
        ft.ElevatedButton("Open modal dialog", on_click=open_dlg_modal),
    )

ft.app(target=main)

Es posible que se este generando algún error al momento de abrir alguna de las ventanas, pero el código funciona bien. En la consola, que error aparece?

there are no errors in the console

can you provide more information to your flet development environment and steps on how to reproduce the issue?

[ndonkoHenri]

I was able to repro in v0.12.0 and i thought this caused it, but the issue is reproducable in v0.11.0 too. 😕

[7576457]

Yes, I have linux ubuntu 22 04, the development environment is VSCode, the flet version is 0.12.0, the device I'm testing on is an iPhone SE 2016.
Initially, I had a version of flet 0.5, but I had such a bug there too. After upgrading to version 12, everything is the same.

I opened an issue for that: #2073
