Methods

addListener(VoidCallback listener) → void
Register a closure to be notified when it is time to repaint.
inherited
buildStillDot(int i, Size size) RRect
Builds a single still dot
inherited
calcPortalTravel(Size size, double offset, double dotOffset) RRect
Calculates the shape of a dot while portal-traveling form last-to-first dot or form first-to-last dot
inherited
hitTest(Offset position) bool?
Called whenever a hit test is being performed on an object that is using this custom paint delegate.
inherited
maskStillDots(Size size, Canvas canvas) → void
Masks spaces between dots
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
paint(Canvas canvas, Size size) → void
Called whenever the object needs to paint. The given Canvas has its coordinate space configured such that the origin is at the top left of the box. The area of the box is the size of the size argument.
override
paintStillDots(Canvas canvas, Size size) → void
Paints count number of dots with no animation
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that the object notifies when it is time to repaint.
inherited
shouldRebuildSemantics(covariant CustomPainter oldDelegate) bool
Called whenever a new instance of the custom painter delegate class is provided to the RenderCustomPaint object, or any time that a new CustomPaint object is created with a new instance of the custom painter delegate class (which amounts to the same thing, because the latter is implemented in terms of the former).
inherited
shouldRepaint(covariant IndicatorPainter oldDelegate) bool
Called whenever a new instance of the custom painter delegate class is provided to the RenderCustomPaint object, or any time that a new CustomPaint object is created with a new instance of the custom painter delegate class (which amounts to the same thing, because the latter is implemented in terms of the former).
inherited
toString() String
A string representation of this object.
