PaintParticle class

A particle which renders its child with certain Paint Could be used for applying composite effects. Be aware that any composite operation is relatively expensive, as involves copying portions of GPU memory. The less pixels copied, the faster it'll be.

PaintParticle({required Particle child, required Paint paint, Rect bounds = const Rect.fromLTRB(-50, -50, 50, 50), double? lifespan})

Properties

bounds → Rect
Defines Canvas layer bounds for applying this particle composite effect. Any child content outside this bounds will be clipped.
