A cubic animation curve that starts slowly and ends quickly. This curve is
based on an exponential equation where
f(t) = 2¹⁰⁽ᵗ⁻¹⁾.
Using this curve can give your animations extra flare, but a longer duration may need to be used to compensate for the steepness of the curve.
Compared to Curves.easeInQuint, this curve is slightly steeper.
Derived from Robert Penner’s easing functions.
static const Cubic easeInExpo = Cubic(0.95, 0.05, 0.795, 0.035);
