blank screen when set expand=1 to ft.Containers

[balabas]

Question

Hello, can't figure, how to create scrollable elements, I trying to make ListView scrollable, but when I set expand=1 for parent Containers, app shows blank screen. If I set expand=0 to Containers app shows controls, but ListView not expanding.

Flet version - 0.23.2

Is blank screen issue or correct work? If correct, how to make ListView scolling?

Code sample

import flet as ft
def main(page: ft.Page):
    page.auto_scroll = True
    page.add(
        ft.Column(
            expand=1,
            scroll=ft.ScrollMode.ALWAYS,
            controls=[
                         ft.Container(
                             expand=1,
                             content=ft.Row(
                                 expand=1,
                                 scroll=ft.ScrollMode.ALWAYS,
                                 wrap=True,
                                 controls=[
                                     ft.Text(value="123"),
                                     ft.Text(value="123"),
                                     ft.Container(
