Notes

AnimationController is a class that we can use to play an animation forward or in reverse,

• by default, AnimationController produces values that range from 0 to 1, during a given duration.
• AnimationController generates a new value whenever Flutter needs to draw a new frame (using a Ticker)

Setting up an AnimationController requires 5 steps:

1. Create a StatefulWidget
2. add SingleTickerProviderStateMixin to the State class
3. create a late final AnimationController _animationController;
4. initialize this AnimationController in initState()
5. Dispose it in the dispose() method
