BouncingParticle.random constructor

BouncingParticle.random(Size area)

Implementation

factory BouncingParticle.random(Size area) {
  Vector2 velocity = randomVector(-2, 2);
  Vector2 position = Vector2(area.width / 2, area.height / 2);
  double radius = 25 + Random().nextDouble() * 40;

  return BouncingParticle(
    area: area,
    basePosition: position.clone(),
    position: position.clone(),
    velocity: velocity,
    radius: radius,
    baseRadius: radius,
  );
}
