# easeInCubic constant Null safety

A cubic animation curve that starts slowly and ends quickly. This curve is
based on a cubic equation where `f(t) = t³`

. The result is a safe sweet
spot when choosing a curve for widgets animating off the viewport.

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

Derived from Robert Penner’s easing functions.

## Implementation

```
static const Cubic easeInCubic = Cubic(0.55, 0.055, 0.675, 0.19);
```
