A cubic animation curve that starts quickly and ends slowly. This is effectively the same as Curves.decelerate, only simulated using a cubic bezier function.
Compared to Curves.easeOutSine, this curve is slightly steeper.
Derived from Robert Penner’s easing functions.
static const Cubic easeOutQuad = Cubic(0.25, 0.46, 0.45, 0.94)
