easeOutQuart constant
A cubic animation curve that starts quickly and ends slowly. This curve is a flipped version of Curves.easeInQuart.
Animations using this curve or steeper curves will benefit from a longer duration to avoid motion feeling unnatural.
Compared to Curves.easeOutCubic, this curve is slightly steeper.
Derived from Robert Penner’s easing functions.
Implementation
static const Cubic easeOutQuart = Cubic(0.165, 0.84, 0.44, 1.0);
