There really isn't much KivyMD experience here.

KivyMD is a very different component implementation from Kivy, though it does depend on Kivy infrastructure.

A quick search here show a related question for Kivy:

The basic method would be to use a background image consisting of as few as two pixels, one blue and one pink, and letting Kivy interpolate them. You can do this entirely programmatically, but generating the image externally may be an easier way to get started.
