[Bug] There is a tiny gap between GrabbingWidget and SnappingSheetContent

[DarkMikey]

If there is no separator between grabbing handle and bottom sheet you can see the background shine through. Would it be possible to fix this? :)

How to reproduce
I basically replaced the background of your example app with a red container and removed the separator in the handle.

flutter doctor -v

@AdamJonsson
Yes please that's an issue, any thoughts on how to circumvent this? Even a work-around maybe?

One work-around comes to mind applied from user-end, is getting not using grabber property altogether and incorporate the grabber widget into sheetBlow, thought I would love to keep using the grabber property.

Just add solid white shadow at bottom of your grabbing widget

BoxShadow(
    blurRadius: 2,
    spreadRadius: 2,
    color: Colors.white,
    offset: Offset(0, 10),
)

tricky, but it's work 😄
