SingleChildParticle mixin

Implements basic behavior for nesting Particle instances into each other.

class BehaviorParticle extends Particle with SingleChildParticle {
  Particle child;

  BehaviorParticle({
    required this.child
  });

  @override
  update(double dt) {
    // Will ensure that child [Particle] is properly updated
    super.update(dt);

    // ... Custom behavior
  }
}
