lerp static method

SpotlightStyle? lerp(
  1. SpotlightStyle? a,
  2. SpotlightStyle? b,
  3. double t
)

Linearly interpolates between two SpotlightStyles.

Implementation

static SpotlightStyle? lerp(SpotlightStyle? a, SpotlightStyle? b, double t) {
  if (a == null && b == null) {
    return null;
  }
  if (a == null) {
    return b;
  }
  if (b == null) {
    return a;
  }
  if (t == 0.0) {
    return a;
  }
  if (t == 1.0) {
    return b;
  }

  return SpotlightStyle(
    radius: lerpDouble(a.radius, b.radius, t),
    gradient: Gradient.lerp(a.gradient, b.gradient, t),
  );
}
