A cubic animation curve that starts slowly, speeds up shortly thereafter, and then ends slowly. This curve can be imagined as a steeper version of easeInOutCubic.
The result is a more emphasized eased curve when choosing a curve for a widget whose initial and final positions are both within the viewport.
Compared to Curves.easeInOutCubic, this curve is slightly steeper.
