Implementation

static AlertStyle? lerp(AlertStyle? a, AlertStyle? b, double t) {
  if (a == null && b == null) {
    return null;
  }
  if (a == null) {
    return t < 0.5 ? null : b;
  }
  if (b == null) {
    return t < 0.5 ? a : null;
  }
  return AlertStyle(
    color: Color.lerp(a.color, b.color, t),
    backgroundColor: Color.lerp(a.backgroundColor, b.backgroundColor, t),
    icon: t < 0.5 ? a.icon : b.icon,
    iconSize: lerpDouble(a.iconSize, b.iconSize, t),
