Describe the bug

Client IP can not be gotten when using IPv6.

For example, my IPv6 is [2409:8a50:480:1c54:16b1:4637:d98f:5e2a], but it shows 2409.

By the way.. How can I settle the text on the center of the page..?

Can you please try the latest pre-release and let know if the issue still happens?
It works on my end (macOS):

import flet as ft


def main(page: ft.Page):
    page.horizontal_alignment = ft.CrossAxisAlignment.CENTER
    page.add(ft.Text(f"My IP: {page.client_ip}"))


ft.run(main, view=ft.AppView.WEB_BROWSER)
