flip_box_bar_plus 0.9.3

A 3D BottomNavigationBar inspired by Dribbble design by Dannniel

[0.9.2] - 12/12/18.

• BREAKING CHANGE: Initial index is replaced by selectedIndex. Earlier versions of the package did not need the user to explicitly modify the chosen index when tapped. From 0.9.0, users need to change the selectedIndex property. See README and examples for clarity.

• Added docs.

• 0.9.1 hotfix
