Describes the clip that would be applied to contents of this layer,
if any.
inherited
-
detach()
→ void
-
Mark this layer as detached from its owner.
inherited
-
dispose()
→ void
-
Clears any retained resources that this layer holds.
inherited
-
find<S extends Object>(Offset localPosition)
→ S?
-
Search this layer and its subtree for the first annotation of type
S
under the point described by localPosition.
inherited
-
findAllAnnotations<S extends Object>(Offset localPosition)
→ AnnotationResult<S>
-

S under
the point described by localPosition.
inherited
-
findAnnotations<S extends Object>(AnnotationResult<S> result, Offset localPosition, {required bool onlyFirst})
→ bool
-

S at the
location described by localPosition.
inherited
