# easeInQuint constant Null safety

A cubic animation curve that starts slowly and ends quickly. This curve is
based on a quintic equation where `f(t) = t⁵`

.

Compared to Curves.easeInQuart, this curve is slightly steeper.

Derived from Robert Penner’s easing functions.

## Implementation

```
static const Cubic easeInQuint = Cubic(0.755, 0.05, 0.855, 0.06);
```
