MultiplePointsClipper class
MultiplePointsClipper is the clipper which extends the CustomClipper and clips the edge of the container in zig-zag shape.
heightOfPoint is the parameter which decides the height of the point.
Default value of height of point is 12.0
.
numberOfPoints is the parameter which decides the number of points.
Default value of number of points is 16
.
Sides is the parameter which decides the side of points Sides.bottom or Sides.vertical on which side the container is to be clipped.
The getClip method is called whenever the custom clip needs to be updated.
The shouldReclip method is called when a new instance of the class is provided, to check if the new instance actually represents different information.

Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be notified when it is time to reclip.
inherited
-
getApproximateClipRect(
Size size) → Rect -
Returns an approximation of the clip returned by getClip, as
an axis-aligned Rect. This is used by the semantics layer to
determine whether widgets should be excluded.
inherited
-
getClip(
Size size) → Path -
Returns a description of the clip given that the render object being
clipped is of the given size.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that the
object notifies when it is time to reclip.
inherited
-
shouldReclip(
covariant CustomClipper oldClipper) → bool -
Called whenever a new instance of the custom clipper delegate class is
provided to the clip object, or any time that a new clip object is created
with a new instance of the custom clipper delegate class (which amounts to
the same thing, because the latter is implemented in terms of the former).
override
-
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
