Particle({ required Color color, required double size, required double angle, required double velocity, double rotationAngle = 0.0, double lifetime = 1.0, double startTime = 0.0, })

Implementation

Particle({
  required this.color,
  required this.size,
  required this.angle,
  required this.velocity,
  this.rotationAngle = 0.0,
  this.lifetime = 1.0,
  this.startTime = 0.0,
});
