Methods

addListener(VoidCallback listener) → void
Register a closure to be notified when it is time to repaint.
inherited
calculateAspectRatio(Size size) → double
inherited
calculateCenter(Size size) → Offset
inherited
calculateSize(Size size) → double
inherited
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) → FlagParentBounds?
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
paintChild(Canvas canvas, Rect parentBounds, ElementsProperties? child) → FlagParentBounds?
inherited
paintCreator([Color? color]) → Paint
inherited
painter(Shape child) → ElementsPainter Function(ElementsProps?, double)
inherited
paintFlagElements(Canvas canvas, Size size, [FlagParentBounds? parent]) → FlagParentBounds?
override
ratioAdjustedSize(Size childSize, {FlagParentBounds? parent, double minRatio = 1.1}) → Size
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
shapeType<T extends Shape>([Shape? shape]) → T?
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).
inherited
toString() → String
A string representation of this object.
inherited

Operators

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