[Question] Flet web app static publish, browser shows blank screen

[psksvp]

Question

I have a web app which works fine in dynamic mode (flet run --web --port 8000 main.py). It uses flet_map package. The app does not use any other package which pyodide does not support. However when I try to publish as static website, the browser shows just blank screen. I tested it on both Firefox and Safari.

'flet build web --include-packages flet_map' produces the following log

'flet publish main.py" produces the following log

I've upgraded flet to 0.25.1 from 0.22 and flet publish main.py works. Thanks.
