Methods

addListener(VoidCallback listener) → void

Register a closure to be notified when it is time to repaint.

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) → 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

sPaint(Solandra s, Size size) → void

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
