transformInternal method

  1. @override
double transformInternal (
  1. double t
)
override

Returns the value of the curve at point t.

The given parametric value t will be between 0.0 and 1.0, inclusive.

Implementation

@override
double transformInternal(double t) {
  final double s = period / 4.0;
  t = t - 1.0;
  return -math.pow(2.0, 10.0 * t) * math.sin((t - s) * (math.pi * 2.0) / period) as double;
}
