PrismFabMenu class

A floating action button that expands into a menu of actions.

Useful when a screen has two or three primary actions and a plain FAB cannot express them all. Opens with a rotation and staggered labels.

PrismFabMenu(
  actions: [
    PrismFabAction(icon: Icons.note_add, label: 'New note', onTap: () {}),
    PrismFabAction(icon: Icons.photo, label: 'New photo', onTap: () {}),
  ],
)
