How to change button color in kivyMD

[Remo G]

i've a 

'MDFillRoundFlatButton' in my application but somehow i cannot change its color.

Not exactly the same case, but a snippet from some code of mine adjusting the shade of MDRoundFlatButton.

The whole point of MD is it is a set of design rules, so you can't do what ever you want because of the rules :(

  

        b = MDRoundFlatButton()
        c = MDApp.get_running_app().theme_cls.primary_palette
        h = MDApp.get_running_app().theme_cls.primary_hue
        b.md_bg_color = get_color_from_hex(MDcolors[c][str(int(h)+100)])
        b.text_color = MDApp.get_running_app().theme_cls.text_color

I'm sorry but I don't get what MDApp means, I'm using KivyMD and I want to change  the button color using its id from python at the end of a function. Should I import sth before writing the variables "c" and "h"?

MDApp is the root class of any KivyMD app. Just search in your app and you will find it imported near the top and used closer to the bottom.
