I think you can use a stack with absolute positioning:

Here is an example:

import flet as ft

def main(page: ft.Page):
    page.overlay.append(ft.Container(ft.Text("I'm inside a container!"), bgcolor="yellow", padding=20, border_radius=5, bottom=20, left=20, right=20))

    page.scroll = "auto"
    for i in range(0, 100):
        page.controls.append(ft.Text(f"Line {i}"))
    page.update()

ft.app(target=main)

Way more better approach.
