lerp static method
- LinearBorderEdge? a,
- LinearBorderEdge? b,
- double t
Linearly interpolates between two LinearBorders.
If both a and b are null then null is returned. If a is null
then we interpolate to b varying size from 0.0 to b.size. If b
is null then we interpolate from a varying size from a.size to zero.
Otherwise both values are interpolated.
Implementation
static LinearBorderEdge? lerp(LinearBorderEdge? a, LinearBorderEdge? b, double t) {
if (identical(a, b)) {
return a;
}
a ??= LinearBorderEdge(alignment: b!.alignment, size: 0);
b ??= LinearBorderEdge(alignment: a.alignment, size: 0);
return LinearBorderEdge(
size: lerpDouble(a.size, b.size, t)!,
alignment: lerpDouble(a.alignment, b.alignment, t)!,
);
}
