[Question] Alternative way to get the client ip from the browser in flet web app, if page.client_ip is empty?

[alexrjs]

Question

I implemented my on session database and I want to use the client ip as id for client specific data, but the page.client_ip is always empty. And client storage is also not working (timeout problem) and session storage is temporary only.

I use the following command to start flet in web mode:

flet run --web --port 8000 --name poc main.py

Is there another way to get a browser/client specific id I can use for my session db?

Code sample

import flet as ft

def main(page: ft.Page):
    _text = page.client_ip
    page.title = "Basic elevated buttons"
    page.add(
        ft.ElevatedButton(text=f"IP: {_text}"),
        ft.Button("Disabled button", disabled=True),
    )

ft.app(main)

Error message
