EdgePainter<E> class

The main Painter for drawing the arrows between the nodes.

Inheritance

Constructors

EdgePainter({required OrgChartController<E> controller, required Paint linePaint, double cornerRadius = 10})

Properties

controller ↔ OrgChartController<E>
The graph that contains the nodes we want to draw the arrows for.
getter/setter pair
cornerRadius ↔ double
getter/setter pair
hashCode → int
The hash code for this object.
no setterinherited
linePaint ↔ Paint
The paint to draw the arrows with
getter/setter pair
linePath ↔ Path
the path of the arrows
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
semanticsBuilder → SemanticsBuilderCallback?
Returns a function that builds semantic information for the picture drawn by this painter.
no setterinherited

Methods

addListener(VoidCallback listener) → void
Register a closure to be notified when it is time to repaint.
inherited
allLeaf(List<Node<E>> nodes) → bool
returns True if no nodes
drawArrows(Node<E> node, Canvas canvas) → dynamic
This function is called recursively to draw the arrows for each node and the nodes below it. i want to add a border radius to the arrows later on, the commented code is a wrong implementation of that. There is a lot of things i want to change here, the way the arrows are drawn, style, and animations.
drawArrowsLeftToRight(Node<E> node, Canvas canvas) → dynamic
drawArrowsTopToBottom(Node<E> node, Canvas canvas) → dynamic
drawDashedLine({required Canvas canvas, required Offset p1, required Offset p2, required int dashWidth, required int dashSpace, required Paint paint}) → 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
toString() → String
A string representation of this object.
inherited

Operators

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