I've been trying to get a favicon working in flet, but I just can't figure out how to do it. The documentation doesn't say anything about making custom favicons, so I just wanted to know if it was possible or not.
I tried using the assets_dir parameter in flet.app but I didn't know what to do next.
A recent post on the official Flet Development blog answers this questions I think. Essentially an updated Flet repo adds PyInstaller functionality into a flet pack command. See the post below.

Or if you are not packaging it, the method you used works i.e.,
ft.app(target=main, view=ft.WEB_BROWSER, assets_dir="assets")
You just need to ensure you have created the assets folder and a file called favicon.png inside the folder.
