As an aside, I noticed that since my system brightness is dark, some cupertino samples use dark mode as well. I wonder if we should just hardcode the theme to be light...

Currently, Cupertino examples adapt to system brightness, which the examples dark in the light API page theme.

Light	Dark

Solution

Add a hardcoded theme with Brightness.light in the examples
