Description
**Description of current situation**
If I understand correctly, the [M3 Expressive Lists](https://github.com/material-components/material-components-android/blob/master/docs/components/List.md) are the new way for building a [Preference Screen](https://developer.android.com/develop/ui/views/components/settings/organize-your-settings) as the `PreferenceScreen` is obviously not redesigned anymore for M3 (Expressive).
Currently, the Catalog app contains some M3 Expressive examples with `Lists` (ListItemCardView), including components such as RadioButtons (`MaterialButton`), CheckBoxes (`MaterialCheckBox`), etc.
**Describe the solution you'd like**
It would be great if you can add a small feature / enhancement e.g. to the ListItemCardView example that shows how to save the settings, e.g. from RadioButtons (`MaterialButton`), CheckBoxes (`MaterialCheckBox`), etc. to the persistent storage. When closing / re-opening the app, the settings should be reloaded from the persistent storage.
