some issues with Theme.use_material3

[ndonkoHenri]

Description
there seems to be an issue with my program when i make changes to its page.theme

Code example to reproduce the issue:

from flet import *
from flet import icons, colors


def main(page: Page):
    page.title = "Material design error"
    page.theme_mode = "light"
    page.window_width = 350
    page.window_height = 300

    page.theme = Theme(use_material3=False)
    page.dark_theme = Theme(use_material3=False, )

    def change_theme(e):
        page.theme_mode = "light" if page.theme_mode == "dark" else "dark"
        theme_icon_button.selected = not theme_icon_button.selected
        page.update()

    theme_icon_button = IconButton(icons.DARK_MODE, selected_icon=icons.LIGHT_MODE, icon_color=colors.BLACK,
                                   icon_size=35, tooltip="change theme", on_click=change_theme,
                                   style=ButtonStyle(color={"": colors.BLACK, "selected": colors.WHITE}, ), )

    page.appbar = AppBar(title=Text("Colors Browser", color="white"), center_title=True, bgcolor="blue",
                         actions=[theme_icon_button], )

    page.add(
        Text(
            "Change the theme_mode, and notice the icon won't change only when 'Theme.use_material3=False'")
    )

flet.app(target=main)

Describe the results you received:

The button at the top_right(theme_icon_button) used to change the theme_mode, doesn't work normally.
The theme_mode is changed as expected, but the button's icon is not changed.

Describe the results you expected:

The theme_mode and the button's icon should change accordingly.

Additional information you deem important (e.g. issue happens only occasionally):

page.theme = Theme(use_material3=True)
page.dark_theme = Theme(use_material3=True, )

OR

page.theme = Theme(use_material3=False)
page.dark_theme = Theme(use_material3=True, )

changes both the button's icon and the theme_mode, just as expected.

Flet version (pip show flet):
flet 0.1.62

Operating system:
Windows
