sameLengthLerp static method
Linearally interpolate between PrimitiveGradient
s a
and b
at any
given keyframe (double
) t
, generally 0.0 .. 1.0
.
This method presumes the gradients have the same number of colors.
Implementation
static PrimitiveGradient sameLengthLerp(
PrimitiveGradient a,
PrimitiveGradient b,
double t,
) {
assert(a.colors.length == b.colors.length, 'list lengths should be equal');
final length = a.colors.length;
final lerpedStops = _mergeListDouble(a.stops, b.stops, t);
final lerpedColors = <Color>[
for (int i = 0; i < length; i++) Color.lerp(a.colors[i], b.colors[i], t)!,
];
return PrimitiveGradient._(lerpedColors, lerpedStops);
}
