transform method

@override double? transform(double t)

Returns the value of the object at point t.

The value of t is nominally a fraction in the range 0.0 to 1.0, though in practice it may extend outside this range.

See also:

• evaluate, which is a shorthand for applying transform to the value of an Animation.
• Curve.transform, a similar method for easing curves.

Implementation

@override
double? transform(double t) {
  if (t <= 0.5) {
    return lerpDouble(small, big, t);
  } else {
    return lerpDouble(big, small, t);
  }
}
