Constructors

PathPainter(Animation<double> animation, List<PathSegment> pathSegments, Size? customDimensions, List<Paint> paints, PaintedSegmentCallback onFinishCallback, bool scaleToViewport, DebugOptions debugOptions)

Properties

animation → Animation<double>
final
canPaint ↔ bool
Status of animation
getter/setter pair
customDimensions ↔ Size?
User defined dimensions for canvas
getter/setter pair
debugOptions ↔ DebugOptions
getter/setter pair
hashCode → int
The hash code for this object.
no setterinherited
onFinishCallback ↔ PaintedSegmentCallback
Evoked when frame is painted
getter/setter pair
paints ↔ List<Paint>
Substitutes the paint object for each PathSegment
getter/setter pair
pathBoundingBox ↔ Rect
Total bounding box of all paths
getter/setter pair
pathSegments ↔ List<PathSegment>
Each PathSegment represents a continuous Path element of the parsed Svg
getter/setter pair
recorder ↔ PictureRecorder
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
scaleToViewport ↔ bool
getter/setter pair
semanticsBuilder → SemanticsBuilderCallback?
Returns a function that builds semantic information for the picture drawn by this painter.
no setterinherited
strokeWidth ↔ double
For expanding the bounding box when big stroke would breaks the bb
getter/setter pair

Methods

addListener(VoidCallback listener) → void
Register a closure to be notified when it is time to repaint.
inherited
calculateBoundingBox() → void
calculateScaleFactor(Size viewBox) → _ScaleFactor
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
onFinish(Canvas canvas, Size size, {int lastPainted = -1}) → void
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.
inherited
paintOrDebug(Canvas canvas, Size size) → Canvas
paintPrepare(Canvas canvas, Size size) → void
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 PathPainter old) → 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.
inherited
viewBoxToCanvas(Canvas canvas, Size size) → void
writeToFile(Picture picture, String fileName, Size size) → Future<void>

Operators

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