Feature request: prop for setting color scheme

[gorbypark]

I have an app where the user can select if they want to use dark mode, light mode or system. When system is selected, then whatever the phone is set to will be used. The menus change color as expected in "system" mode, but of course use whatever system color is when in dark or light mode. I would love to be able to force either light or dark mode when needed.

Thanks for the great lib!

Ah this is known i think. This is slightly different than #108 but similar concept
