VectorImagePainter class

CustomPaint used for drawing Vector elements into a canvas.

Inheritance

Constructors

VectorImagePainter({@required List<VectorDrawableElement> vectorDefinition, double baseImageSize })
Only vectorDefinition is required vectorDefinition (List of VectorDrawableElement) : Elements that compose the Vector to be drawn baseImageSize (double) : Size of the original image

Properties

baseImageSize ↔ double
Size of the original image
read / write
vectorDefinition ↔ List<VectorDrawableElement>
Elements that compose the Vector to be drawn
read / write

Methods

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
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
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 non-existent method or property is accessed.
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
toString() → String
Returns a string representation of this object.

Operators

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