IPainter class abstract

Abstract base class for implementing custom painters used in ICanvas.

IPainter handles painting, animation controllers, and repaint management. Extend this class to create animated or interactive canvas effects.

Constructors

animations → List<Animation<double>>: List of active Animations, primarily used for double interpolations.
final
center ↔ Offset: The center point of the canvas.
getter/setter pair
controllers → List<AnimationController>: List of active AnimationControllers used by this painter.
final
hashCode → int: The hash code for this object.
no setterinherited
height ↔ double: The current height of the canvas.
getter/setter pair
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
shouldRepaint → bool: Whether the painter should repaint on every frame.
no setter
width ↔ double: The current width of the canvas.
getter/setter pair

createAnimation<T>({required TickerProvider vsync, required AnimationController controller, required Tween<T> tween, VoidCallback? listener}) → Animation<T>: Creates and manages a tween-based Animation from a given controller.
createController({required TickerProvider vsync, required Duration duration, bool repeat = true, bool reverse = false, VoidCallback? listener}) → AnimationController: Creates and manages an AnimationController.
dispose() → void: Disposes all animation controllers and clears associated data.
initialize({required double width, required double height, required Offset center, required TickerProvider vsync, required ValueNotifier<bool> repaintNotifier, required bool isFirstInilize}) → void: Initializes the painter with canvas dimensions and setup information.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
onInit(TickerProvider vsync) → void: Override this method to perform setup such as creating animations.
render(Canvas canvas, Size size) → void: Renders the custom drawing logic on the given Canvas and Size.
toString() → String: A string representation of this object.
inherited
update() → void: Triggers a repaint by toggling the repaint notifier.
