FilledButton and FilledToneButton doesn't respect the style keyword

[johnnychen94]

Description

The style keyword is not respected by either the FilledButton or FilledToneButton when setting color and bgcolor values using the new ButtonStyle flavor.

Code example to reproduce the issue:

import flet as ft

def main(page: ft.Page):
    page.bgcolor = ft.colors.BLACK

    btn = ft.FilledButton(
        text="Install",
        style=ft.ButtonStyle(
            bgcolor={
                ft.MaterialState.DISABLED: ft.colors.RED_500,
                "": ft.colors.BLUE_400,
            },
            color={
                "": ft.colors.WHITE,
            },
        ),
        disabled=True,
    )

    page.add(btn)


ft.app(target=main)

Describe the results you received:

Describe the results you expected:

The background color should be ft.colors.RED_500 as style specifies.

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

This one is similar to #1754. I believe the default value passing of FilledButton color/bgcolor/elevation needs to be carefully revisited or redesigned.

I believe this is a bug because it's not consistent with other button types:

        disabled=disabled,
    )


def build_button_row(ButtonType):
    btn = build_button(ButtonType, disabled=False)
    btn_disabled = build_button(ButtonType, disabled=True)
    return ft.Row([ft.Text(f"{ButtonType}:"), btn, btn_disabled])


def main(page: ft.Page):
    page.bgcolor = ft.colors.BLACK

    rows = []
    for btnType in [
        ft.ElevatedButton,
        ft.FilledButton,
        ft.FilledTonalButton,
        # ft.FloatingActionButton, # `style` keyword not supported
        ft.TextButton,
        ft.OutlinedButton,
    ]:
        rows.append(build_button_row(btnType))

    page.add(ft.Column(rows))


ft.app(target=main)
