Notes

To implement the page flip animation, we will need the following:

• AnimationController
• AnimatedBuilder & AnimatedWidget
• Matrix transforms
• Gesture detectors

We'll also see how to use a GlobalKey to modify the state of a child widget from the parent widget.

Note: as some of the code for enabling the page flip effect is quite complex, we will implement the basics by hand, then switch over to the page_flip_builder package on pub.dev.
