Refresh Scroll in Column

[ingdesarr1]

Question

Good morning. I'm trying to use a Banner with a Column, to add containers and generate a list of elements, or alarms, but, when I add a new element to the column, the scroll is not updated, that is, the bar maintains its size, and if I move the scroll, it jumps to the first or last element. I would like that, as new elements are added, the scroll would adapt to move between them more easily. Is there a way to update it. Thank you

Code sample

banner = ft.Banner(
        bgcolor=ft.colors.AMBER_100,
        content_padding=5,
        leading=ft.Icon(ft.icons.WARNING_AMBER_ROUNDED, color=ft.colors.AMBER, size=40),
        content=ft.Column(
            scroll="AUTO",
            height=50
        ),
        actions=[
            ft.IconButton(icon=ft.icons.ACCESS_ALARM_ROUNDED,visible=True,icon_color="transparent")
        ],
    )

def cierre(e):
        largo = len(banner.content.controls[:])
        for i in range(0,largo):
            el = banner.content.controls[i]
            if el.data == e.control.data:
                print(el.data,i)
                banner.content.controls.pop(i)
                break
        banner.content.update()
        if len(banner.content.controls[:])==0:
            banner.open = False
            page.update()

def prueba(e):
        e.control.data += 1
        contenedor = ft.Container(
            content=ft.Row(
                controls=[
                    ft.Text(f"Mensaje No. {e.control.data}"),
                    ft.IconButton(icon=ft.icons.CLOSE_ROUNDED,on_click=cierre,data=e.control.data)
                ]
            ),
            data=e.control.data,
            height=50
        )
        banner.content.controls.insert(0,contenedor)
        banner.content.update() if banner.open else None
        print(len(banner.content.controls[:]))
        page.banner = banner
        banner.open = True
        page.update()

ft.IconButton(ft.icons.ABC_ROUNDED,on_click=prueba,icon_color="red",data=0)
