Question

I tried building a static flet app with flet publish but was getting an attribute error. I thought it was just my app but even examples failed to work when built with flet publish. Is there a breaking that was introduced?

Code sample

import flet as ft

def main(page: ft.Page):
    def bs_dismissed(e):
        print("Dismissed!")

    def show_bs(e):
        bs.open = True
        bs.update()

    def close_bs(e):
        bs.open = False
        bs.update()

    bs = ft.BottomSheet(
        ft.Container(
            ft.Column(
                [
                    ft.Text("This is sheet's content!"),
                    ft.ElevatedButton("Close bottom sheet", on_click=close_bs),
                ],
                tight=True,
            ),
            padding=10,
        ),
        open=True,
        on_dismiss=bs_dismissed,
    )
    page.overlay.append(bs)
    page.add(ft.ElevatedButton("Display bottom sheet", on_click=show_bs))

ft.app(target=main)
