lerp static method
Linearly interpolates between two NodeTransforms.
Implementation
static NodeTransform? lerp(NodeTransform? a, NodeTransform? b, double t) {
if (a == null && b == null) return null;
if (a == null) return b;
if (b == null) return a;
return NodeTransform(
x: lerpDouble(a.x, b.x, t)!,
y: lerpDouble(a.y, b.y, t)!,
r: lerpDouble(a.r, b.r, t)!,
opacity: lerpDouble(a.opacity, b.opacity, t)!,
);
}
