Constructors

HirahiraDropPhysics(Size size, {double? rotationSpeed, double? rotationDirection, double baseFallSpeed = 0.7, int fps = 60, double minShiftValue = 1.5, double maxShiftValue = 3.0})
  • size : The widget size.
  • rotationSpeed : The object rotation speed.
  • rotationDirection : Specifies whether to rotate the object counterclockwise or clockwise, as 1 or -1. If not specified, a random value will be set.
  • baseFallSpeed :　Parameters for control of falling speed. The actual speed is obtained by adding 0 to 1 to this speed.
  • fps : The screen fps.
  • minShiftValue : Parameters related to petal swing width.
  • maxShiftValue : Parameters related to petal swing width.
