Describe the bug

Using alignment and expand=False in Container give me an unexpected result.
I want my Container not to expand.
In the following example, the first Container give me an expected result (without alignment).
Then, I want to align the text, and the second Container give me an expanded Container.
Is this normal ?

import flet as ft

def main(page: ft.Page):
    page.add( 
        ft.Container(
            ft.Column(
                [
                    ft.Container( ft.Text("Hello"), expand=False, height=50, bgcolor='amber' ),
                    ft.Container( ft.Text("Hello"), expand=False, height=50, bgcolor='orange', alignment=ft.alignment.center_left ),
                ]
            )
        )
    )

ft.app(target=main)

This looks like expected Container behavior inherited from Flutter's design rather than an expand=False bug.

alignment on Container aligns the child inside the container. When alignment is set, the container may grow to fill the space made available by its parent instead of shrinking to the size of its content. In your example, that is why the second container becomes wider while the first one stays content-sized.

expand=False is not what changes this behavior here. In this case, the change comes from alignment, not from expand.

If you want aligned content inside a non-expanding container, a few options are:

• set an explicit size (width in your case)
• keep a fixed-size outer Container and use a nested layout for positioning

For example:

import flet as ft

def main(page: ft.Page):
    page.add(
        ft.Container(
            width=120,
            height=50,
            bgcolor=ft.Colors.ORANGE,
            alignment=ft.Alignment.BOTTOM_RIGHT,
            content=ft.Text("Hello"),
        )
    )

ft.run(main)

Docs will be updated, to make this behavior known.
