Methods

addListener(VoidCallback listener) → void
Register a closure to be notified when it is time to repaint.
inherited
drawDataPoints(List<Offset> points, Canvas canvas, Offset c, Paint dotPaintFill) → void
drawLabelMethod(Canvas canvas, List<String> labels, Offset c, double wd, List<Offset> points, double top) → void
drawTextCentered(Canvas canvas, Offset c, String label, TextStyle labelStyle, double maxwidth) → Size
drawXlabels(Canvas canvas, Offset c, double maxwd) → void
hitTest(Offset position) → bool?
Called whenever a hit test is being performed on an object that is using this custom paint delegate.
inherited
measureText(String s, TextStyle style, double maxwidth, TextAlign align) → TextPainter
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
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.
