cannot get height and width for page

[yinshunyao]

** cannot get height and width. I try it when the page strart or end. **

Code example to reproduce the issue:

def main(page: ft.Page):
    ui_size.update(page.width, page.height)
    page.title = f"xxx"
    logging.warning(f"窗口{page.title}分辨率:{page.width} * {page.height}")
    page.vertical_alignment = ft.MainAxisAlignment.START
    # page.bgcolor = ft.colors.BLUE
    page.opacity = 0.5
    page.spacing = ui_size.spacing
    page.padding = ui_size.page_padding
    from views.view_switch import get_manager_view
    # 定义切换
    page.manager_view = get_manager_view()
    page.manager_view.update_page(page)
    # page.manager_view.switch_main()
    page.manager_view.switch_view(page.manager_view.URL_ORDER_LIST)
    logging.warning(f"last,窗口{page.title}分辨率:{page.width} * {page.height}")

Additional information you deem important (e.g. issue happens only occasionally):

Flet version (pip show flet):

flet                          0.9.0
flet-core                     0.9.0
flet-route                    0.3.2
flet-runtime                  0.9.0

Operating system: macos and ubuntu

the same result in version 0.10.3

Downgraded the flet version, this issue is resolved.

bin/python3 -m pip list | grep flet
flet 0.6.0
flet-core 0.6.0
flet-route 0.3.2
flet-runtime 0.9.0

Nice!

But I didn't understand.
You wanted to print page.width and page.height but nothing was displayed?

I didn't post it. The result is 0.0 and 0.0.

Ah Alright!
That's strange, I must admit.

All flet, flet-core and flet-runtime must be the same version.

I've been able to reproduce that. Looks like a regression.

Code to reproduce:

import flet as ft


def main(page: ft.Page):
    print(page.width, page.height)
    print(page.window_width, page.window_height)
    page.add(ft.Text("Hi!"))

ft.app(main)

Run with flet run -w repro.py.

Expected result:

{x} {y}
0 0

Actual result:

0.0 0.0
0 0
