ClipRRectModifier class
A widget that clips its child using a rounded rectangle.
By default, ClipRRect uses its own bounds as the base rectangle for the clip, but the size and location of the clip can be customized using a custom clipper.
{@tool dartpad} This example shows various ClipRRects applied to containers.
** See code in examples/api/lib/widgets/basic/clip_rrect.0.dart ** {@end-tool}
Troubleshooting
Why doesn't my ClipRRect child have rounded corners?
When a ClipRRect is bigger than the child it contains, its rounded corners could be drawn in unexpected positions. Make sure that ClipRRect and its child have the same bounds (by shrinking the ClipRRect with a FittedBox or by growing the child).
{@tool dartpad} This example shows a ClipRRect that adds round corners to an image.
** See code in examples/api/lib/widgets/basic/clip_rrect.1.dart ** {@end-tool}
