Create the menu without animations

The drawer menu displays a list of titles,
followed by a Get started button at 
the bottom of the menu.

Define a stateful widget called Menu
that displays the list and button 
in static locations.

Prepare for animations

Control of the animation timing requires an
AnimationController.

Add the SingleTickerProviderStateMixin
to the MenuState class. Then, declare and
instantiate an AnimationController.

The length of the delay before every animation is
up to you. Define the animation delays,
individual animation durations, and the total 
animation duration.
