Handles the rendering of pie sections, animations, and hover effects

Inheritance

Constructors

PieChartPainter.new({required List<PieData> data, required double animation, int? hoveredIndex, required double sectionSpace, required double centerRadius, required double sectionStrokeWidth}): Creates a PieChartPainter

animation → double: Animation progress value (0.0 to 1.0)
final
centerRadius → double: Radius of the center circle (for donut charts)
final
data → List<PieData>: Data points to display in the pie chart
final
hashCode → int: The hash code for this object.
no setterinherited
hoveredIndex → int?: Index of the currently hovered section, if any
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
sectionSpace → double: Space between pie sections in logical pixels
final
sectionStrokeWidth → double: Width of each pie section stroke
final
semanticsBuilder → SemanticsBuilderCallback?: Returns a function that builds semantic information for the picture drawn by this painter.
no setterinherited

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: Paints the pie chart on the canvas
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 PieChartPainter oldDelegate) → bool: Determines if the painter should repaint
override
toString() → String: A string representation of this object.
