Describe the bug

Hello,

After upgrading to Flet 0.25.2, I encountered two issues that seem to be related, so I am reporting them together:
Issue 1: FilledTonalButton and FilledButton not displaying

When running a statically packed Flet application (using flet publish), FilledTonalButton and FilledButton do not render. This behavior was not observed in version 0.24.1.
Issue 2: Rounded corners for buttons not working

In version 0.25.2, the shape property for buttons (e.g., ft.RoundedRectangleBorder) no longer works as expected for FilledTonalButton and FilledButton. This issue also appears to have been introduced with the update.

Code sample

import flet as ft

def main(page: ft.Page):
    page.add(
        ft.Column(
            expand=True,
            controls=[
                ft.Column(
                    expand=1,
                    controls=[
                        ft.Text('Issue 1: Problem with displaying FilledTonalButton and FilledButton on a static Flet.'),
                        ft.ElevatedButton('ElevatedButton'),
                        ft.OutlinedButton('OutlinedButton'),
                        ft.FilledButton('FilledButton'),
                        ft.FilledTonalButton('FilledTonalButton'),
                    ]
                ),
                ft.Column(
                    expand=1,
                    controls=[
                        ft.Text('Issue 2: Problem with button rounding on a static Flet.'),
                        ft.ElevatedButton(
                            'ElevatedButton',
                            style=ft.ButtonStyle(shape=ft.RoundedRectangleBorder(radius=5))
                        ),
                        ft.OutlinedButton(
                            'OutlinedButton',
                            style=ft.ButtonStyle(shape=ft.RoundedRectangleBorder(radius=5))
                        ),
                        ft.FilledButton(
                            'FilledButton',
                            style=ft.ButtonStyle(shape=ft.RoundedRectangleBorder(radius=5))
                        ),
                        ft.FilledTonalButton(
                            'FilledTonalButton',
                            style=ft.ButtonStyle(shape=ft.RoundedRectangleBorder(radius=5))
                        ),
                    ]
                ),
            ]
        )
    )

ft.app(main)

To reproduce

Steps to Reproduce:

1. Save the code above as main.py.
2. Use the following commands to publish the app and serve it locally:

   flet publish main.py --assets assets --app-name FletIsAwesome --app-description FletIsAwesome
   python.exe -m http.server 8080 --bind 127.0.0.1 --directory dist
   

3. Access the app in the browser (e.g., http://127.0.0.1:8080).
4. Observe the following issues:
   • Buttons FilledButton and FilledTonalButton do not appear.
   • Rounded corners do not apply to these buttons.

Expected behavior

I expect that when packaging a static application, it should work visually the same as a desktop application. At least in terms of appearance, as shown in the video.

It could be browser cache. Try in InPrivate/Incognito mode. I'm getting this:

I think you're right about the cache. However, clearing it completely or opening it in a new window hasn't worked for me so far. I'll try it on another computer.

I see that issue №1 is not present in your screenshot, but issue №2 is there. If you ran my example code, the corner radius should be set to 5. In other words, it should look more rectangular than what you currently have.

[Klu1d]

Yes, I was able to achieve the desired result in incognito mode, which means it should also be possible without it. Yes, this is related to caching, and it needs to be cleared.

I can confirm #2 issue exists and I can reproduce it. Will be looking into that.
