  1. double t
)
override

Returns the value this variable has at the given animation clock value.

Implementation

@override
Rect lerp(double t) {
  if (_dirty)
    _initialize();
  if (t == 0.0)
    return begin!;
  if (t == 1.0)
    return end!;
  final Offset center = _centerArc.lerp(t);
  final double width = lerpDouble(begin!.width, end!.width, t)!;
  final double height = lerpDouble(begin!.height, end!.height, t)!;
  return Rect.fromLTWH(center.dx - width / 2.0, center.dy - height / 2.0, width, height);
}
