lerp method
Linearly interpolate between this and another FProgressStyle using the given factor t.
Implementation
@useResult
FProgressStyle lerp(FProgressStyle other, double t) => .new(
constraints: .lerp(constraints, other.constraints, t) ?? constraints,
trackDecoration: .lerp(trackDecoration, other.trackDecoration, t) ?? trackDecoration,
fillDecoration: .lerp(fillDecoration, other.fillDecoration, t) ?? fillDecoration,
motion: motion.lerp(other.motion, t),
);
