Methods

addListener(VoidCallback listener) → void
Register a closure to be notified when it is time to repaint.
inherited
drawInfoDialog(Canvas canvas) → void
drawInfoText(Canvas canvas) → void
绘制顶点文字
drawInnerCircle(Canvas canvas, Size size) → dynamic
绘制内圈圆 || 内多边形、分割线 || 绘制文字
drawRadarMap(Canvas canvas, List<double> value, List<double> maxList, Paint mapPaint) → dynamic
绘制区域
drawRadarPath(Canvas canvas, List<double> value, List<double> maxList, Paint linePaint) → dynamic
绘制边框
drawRadarText(Canvas canvas, List<double> value, List<double> maxList, Color color) → void
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.
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
tapDown(TapDownDetails details) → void
tapUp(TapUpDetails details) → void
toString() String
A string representation of this object.
