TicketPassClipper class

TicketPassClipper is the clipper which extends the CustomClipper and clips the container in the shape of ticket or pass.

position is the parameter which decides the position of the clip. Default value of position is width of the container - 16.0.

holeRadius is the parameter which decides the radius of the hole. Default value of radius of hole is 16.

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.
