Add options for taking theme from system settings, i.e. Auto theme

You can use MediaQuery.platformBrightnessOf(context) to get the system's brightness.

Yes I know that but I was thinking if you could implement that somehow in your widget only.
Although I am not quiet sure of how the UI will look in that case

I think it's a bit out of purpose for this plugin. But I've already implemented something like that in one of my apps.
