VerticalDivider not visible if no height defined in parent

[azhago]

Question

Hi,
Not sure it's a bug or not.

If i add a VerticalDivider in, for exemple, a Row, if the row, or none of the parent of the row has a height defined, the VerticalDivider will not show.

If the Row, or a parent control where the row lies, has a height, it will show.

So, with a no height defined control, with expand enabled, it will not be visible

Code sample

import flet as ft

def main(page:ft.Page):
    page.vertical_alignment = ft.MainAxisAlignment.CENTER
    page.add(
        ft.Container(
            border=ft.border.all(3, ft.colors.WHITE),
            padding=15,
            height=300, # => if not commented : VerticalDivider will be visible
            content=ft.Row(
                    # height=300, # => if not commented : VerticalDivider will be visible
                    controls=[
                        ft.Text("Hello", size=20),
                        ft.VerticalDivider(thickness=3, color=ft.colors.WHITE),
                        ft.Text("World", size=20),
                        ft.Container(
                            height=300,
                            width=20,
                            bgcolor=ft.colors.TRANSPARENT
                        )
                    ],)
                    ))


if __name__ == "__main__":
    ft.app(target=main)
