Automatic change of overlayStyle after calling CupertinoScaffold.showCupertinoModalBottomSheet

[HE-LU]

@jamesblasco Hey, I am solving an issue with CupertinoScaffold.showCupertinoModalBottomSheet.

This builder will automatically force a new overlayStyle, leaving me no option to keep the one I have currently set. (I want to use transparent systemNavigationBarColor. Calling this show method will always force new light or dark style, overriding anything I have set.).

I would love to introduce a new PR for you to solve this issue for me. My question would be, what was the reasoning for deprecating overlayStyle parameter? I can imagine that I could use this parameter to solve my issue, or to introduce completely new parameter like overrideOverlayStyle defaulting to true. Actually, I probably do not see any clear solution for handling this case.

Any ideas, please?

wrap the child widget with AnnotatedRegion.

builder: (context) => AnnotatedRegion<SystemUiOverlayStyle>( value: overlayStyle, child: child, ),
