Text color not driven by theme variables

[janeaujanssen]

Similar to #2256, the text color in light or dark mode is not driven by one of the material 3 theme color variables. I would expect to see a change in text color when the page.theme.color_scheme.on_surface variable is changed but this is not the case, neither is it for any of the other named theme colors mentioned here: https://flet.dev/docs/reference/colors/

You can change default text color in page.text_theme. Normal default text is body_medium:

import flet as ft


def main(page: ft.Page):
    page.theme_mode = ft.ThemeMode.DARK
    page.theme = ft.Theme(
        text_theme=ft.TextTheme(body_medium=ft.TextStyle(color=ft.Colors.BLUE)),
    )

    page.dark_theme = ft.Theme(
        text_theme=ft.TextTheme(body_medium=ft.TextStyle(color=ft.Colors.RED)),
    )
    page.add(ft.Text("Text color example"))


ft.app(target=main)

Then in dark theme you will have Red text and in light theme Blue text
