transform method

  1. @override
double transform (double t)
override

Returns the value of the curve at point t.

The value of t must be between 0.0 and 1.0, inclusive. Subclasses should assert that this is true.

A curve must map t=0.0 to 0.0 and t=1.0 to 1.0.

Implementation 

@override
double transform(double t) {
  assert(t >= 0.0 && t <= 1.0);
  if (t == 1.0)
    return 1.0;
  t *= count;
  return t - t.truncateToDouble();
}
