This component doesn’t have state, so it is a Stateless Widget

The Screen should pass the current value and a callback to change the state. So we have this component for each flavor

Current value to be drawn

Callback to signaling to the screen “the value was changed, we need a recomposition”

This represents the user selection

This is coming from the server. Shaggy, and Scooby, please ask the Pizzeria to add more flavors!
