To use it, you must put the
FabNavigationBar widget inside a
MaterialApp widget property
home. The only required properties for the widget are
itens List<FabNavigationBarIcon> (which are the itens which will appear in the
fabCallback (VoidCallback) which is the function executed after we click the Fab button.
