How to set the height of a Container to expand to the window size?

[yunakam]

When the structure of layout controls is:

Page
 |__Container
      |__Column
          |__Sub-column 1 (should not scroll)
          |__Sub-column 2 (should scroll)

To make Sub-column 2 scrollable, a solution was to set the height value for the Container.
I assume there are other solutions to that, but the question here is: Is there a way to adjust the height of a Container to the window size?

In the example below, removing height=500 at line 10 would disable scrolling for Sub-column 2.

Code sample

import flet as ft

itemList = [ft.Text(f"item {x}") for x in range(50)]
    
def main(page: ft.Page):
    page.controls.append(
        
        # Can this be adjusted to the window height?
        ft.Container(
            height=500,
            padding=20,
            
            content=ft.Column(
                controls=[
                    
                    # Sub-column 1 (should not scroll)
                    ft.Column(
                        controls=[ft.Text("Upper part - shouldn't scroll")],
                    ),
                    
                    # Sub-column 2 (should scroll)
                    ft.Column(
                        expand=True,
                        scroll=ft.ScrollMode.AUTO,
                        controls=[
                            ft.Text("Lower part - should scroll"),
                            ft.ExpansionTile(
                                title=ft.Text("ExpansionTile"),
                                controls=[
                                    ft.ListView(
                                        controls=itemList
                                    )
                                ]
                            )
                        ]
                    ),                   
                ]
            )
        ),
    )
    page.update()

ft.app(main)

• I have searched for answers to my question both in the issues and in previous discussions.

Set the expand property of the Container to True, to make it fill the page.

Thank you! It worked with the example which is a simplified version, but not with my actual code turning the entire page blank.. but it must be then a separate issue.
