Description of the Bug
Hello everyone! I'm with a issue with the theme text color. I want to create a snackbar and give to a button the default error text color. But when I change the theme_text_color to "Error" it give-me a None Value Exception. I think that is because in the new update, the default theme text colors aren't implemented... It will be implemented in the future?
Code and Logs
It can be repliqued with a simple creation of a snackbar with the action button with the property theme_text_color.
Like this:
from kivy.metrics import dp
from kivymd.app import MDApp
from kivymd.uix.snackbar import MDSnackbar, MDSnackbarSupportingText, MDSnackbarButtonContainer, MDSnackbarActionButton, \
MDSnackbarActionButtonText
class MainApp(MDApp):
def build(self):
pass
def on_start(self):
MDSnackbar(
MDSnackbarSupportingText(
text="Single-line snackbar with action",
),
MDSnackbarButtonContainer(
MDSnackbarActionButton(
MDSnackbarActionButtonText(
theme_text_color="Error",
text="Action button"
),
),
pos_hint={"center_y": 0.5}
),
y=dp(24),
orientation="horizontal",
pos_hint={"center_x": 0.5},
size_hint_x=0.5,
auto_dismiss=False
).open()
if __name__ == '__main__':
app = MainApp()
app.run()

Attach minimal code

Done. Sorry don't send the minimal code, when I send the issue I was late for an appointment.

I know that this compontent exists, to bypass this issue I use "Custom" theme_text_color and set the text_color to "errorColor", but the optionProperty from theme_text_color accepts "Error", "Hint" and "Secundary", but already this options aren't really accepted, raising a exception. I think that it can be removed to accept only "Primary" and "Custom", the types already supported, or implemented the other. I'm just sharing that this isn't working as expected.
Thank you for the help, and good work!
