Methods

absOffsetOf({required Size size, required Offset offset, Offset spacing = Offset.zero}) → Offset
Returns the absolute offset by a given normalized offset(0 ~ 1) and size.
inherited
addListener(VoidCallback listener) → void
Register a closure to be notified when it is time to repaint.
inherited
constraintBy(ChartPainterConstraint given) → void
Sets the constraint about the current chart layout.
inherited
drawBackground(Canvas canvas, Size size) → void
Draws the background elements of the chart.
inherited
drawForeground(Canvas canvas, Size size) → void
Draws the foreground elements of the chart after background drawing.
override
hitTest(Offset position) → bool?
Called whenever a hit test is being performed on an object that is using this custom paint delegate.
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.
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 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).
override
toString() → String
A string representation of this object.
inherited

Operators

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