GappedSlivers constructor
Creates a GappedSlivers with spacing between slivers.
The spacing parameter defines the size of the gap between slivers.
It must be non-null and positive.
The optional color parameter is useful for debugging to visualize
where gaps are placed.

GappedSlivers({
required double spacing,
required List<Widget> slivers,
Color? color,
}) : super._(
widgets: slivers.sliverGap(spacing, color: color),
);
