TouchInteractionHandler class

Class that handles touch interactions with particles

Optimizations:

• Combines physics and rendering in single pass
• Batched rendering using opacity buckets
• Eliminates duplicate distance calculations

Constructors

TouchInteractionHandler({required List<Particle> particles, required Offset? touchPoint, required double lineDistance, required Color touchColor, required Paint linePaint})

Constructor for the touch interaction handler

Methods

applyTouchPhysics(List<int> visibleParticles) → void

Legacy method for applying touch physics (deprecated) Use handleTouchInteraction instead for better performance

drawTouchLines(Canvas canvas, List<int> visibleParticles) → void

Legacy method for drawing touch lines (deprecated) Use handleTouchInteraction instead for better performance

handleTouchInteraction(Canvas canvas, List<int> visibleParticles) → void

Handles both touch physics and rendering in a single optimized pass

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.
