easeOutSine constant Null safety
A cubic animation curve that starts quickly and ends slowly. This is similar to Curves.easeOut, but with sinusoidal easing for a slightly less abrupt beginning and end. Nonetheless, the result is quite gentle and is hard to distinguish from Curves.linear at a glance.
Derived from Robert Penner’s easing functions.
Implementation
static const Cubic easeOutSine = Cubic(0.39, 0.575, 0.565, 1.0);
