RenderSliverClipRRect constructor
RenderSliverClipRRect({
- RenderSliver? child,
- BorderRadius borderRadius = BorderRadius.zero,
- CustomClipper<
RRect> ? clipper, - Clip clipBehavior = Clip.antiAlias,
Creates a rounded-rectangular clip.
The borderRadius
defaults to BorderRadius.zero, i.e. a rectangle with
right-angled corners.
If clipper
is non-null, then borderRadius
is ignored.
The clipBehavior
argument must not be null or Clip.none.
Implementation
RenderSliverClipRRect({
RenderSliver? child,
BorderRadius borderRadius = BorderRadius.zero,
CustomClipper<RRect>? clipper,
Clip clipBehavior = Clip.antiAlias,
}) : assert(clipBehavior != null),
assert(clipBehavior != Clip.none),
_borderRadius = borderRadius,
super(child: child, clipper: clipper, clipBehavior: clipBehavior) {
// `_borderRadius` has a non-nullable return type, but might be null when
// running with weak checking, so we need to null check it anyway (and
// ignore the warning that the null-handling logic is dead code).
assert(_borderRadius != null || clipper != null); // ignore: dead_code
}
