HELP !!!

Hi,
I fllow this and this to make a hello world extension. My repo here.

Open new uv project, install with
uv add git+https://github.com/hieubnt235/flet-spinkit.git
Add simple python script:

import flet as ft
from flet_spinkit import FletSpinkit

def main(page:ft.Page):
	page.add(FletSpinkit(value="abc"))

app=ft.app(main,export_asgi_app=True)
if __name__=="__main__":
	import uvicorn
	uvicorn.run(app)

and it always show, no matter running in web or linux, using uvicorn or AppView.WEB_BROWSER.

Note that if i build package with flet build web -vv and run python -m http.server /build/web. Everything works. But i want to make it as the regular python package, install with uv and use with my project, just like flet-video, flet-audio,...

Thank you.
