ForegroundPainter class

A custom painter that draws the foreground of the earth globe.

Inheritance

Constructors

ForegroundPainter({required List<AnimatedPointConnection> connections, required double radius, required double rotationZ, required double rotationY, required double rotationX, required double zoomFactor, required List<Point> points, Offset? hoverPoint, Offset? clickPoint, VoidCallback? onPointClicked, required dynamic hoverOverPoint(String pointId, Offset? hoverPoint, bool isHovering, bool isVisible), required dynamic hoverOverConnection(String connectionId, Offset? hoverPoint, bool isHovering, bool isVisible)})
This painter is responsible for rendering the points, connections, and labels on the globe. It takes various parameters such as the list of connections, radius, rotation angles, zoom factor, points, hover point, click point, and callback functions for point interactions.

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
isSame(GlobeCoordinates c1, GlobeCoordinates c2) → bool
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.
