Describe the bug

When I resize the window, the image shrinks only if I resize horizontally. If I add expand=True, the image shrinks also when I resize the window vertically. This happens with every control I've tried. Adding page.vertical_alignment = ft.MainAxisAlignment.CENTER centers the image an make it move when I resize, but still crops the image.

Code sample

Code

import flet as ft


def main(page: ft.Page):

    page.window.height = 500
    page.window.width = 500

    a = ft.Image(
        src='assets/img/x.png',
        width=200,
        height=200,

    )

    page.add(a)


ft.app(main, assets_dir='assets')

To reproduce

Try the code, then try the same adding expand=true, see the difference

Expected behavior

To resize the image when I resize the window vertically without expand. Or to NOT resize the image when I resize the windows horizontally without expand. So I expect to be consistent

Have you tried this on a newer flet release?

[ch3ng666]

Still happens in flet v0.24.1

Someone may correct me, but I think it makes sense if you think of the page as a column by default. Therefore if I modify your code as below without expand on the children of the column or the row, I get the "consistent" behaviour you are expecting (i.e. no resizing).

import flet as ft


def main(page: ft.Page):

    page.window.height = 500
    page.window.width = 500

    a = ft.Image(
        src="https://picsum.photos/200/200?11",
        width=200,
        height=200,
    )
    c = ft.Row(
        [a]
    )

    page.add(c)
    page.update()


ft.app(main)
