clipOverlap property
final
How the clip reacts to the area overlapped by preceding pinned slivers.
When set to ClipOverlapBehavior.followEdge (the default), the clip rectangle is truncated at the overlap boundary defined by SliverConstraints.overlap.
ClipOverlapBehavior.preserveShape produces the same clip rectangle as ClipOverlapBehavior.followEdge, since a plain rectangle has no rounded corners to keep visible. See SliverClipRRect.clipOverlap for the mode where the shape is shifted inward instead of being truncated.
When set to ClipOverlapBehavior.none, no overlap clipping is applied and content may render underneath translucent pinned slivers.
See ClipOverlapBehavior for details on each mode.
