Animations (using code) are one of the things I’m not very fond of in Flutter code. It is setup and controlled in three parts.
This manages the "Animation". It produces a new value for every frame that is rendered, keeps track of the animation state and exposes functionality to play (forward), reverse or stop an animation.
##Animation / Tween: This defines the begin and end values along with how to how move from the beginning to end through a curve. This object will notify the controller through the ValueListenable protocol whenever the value it holds has changed.
##Ticker: A ticker is a class that listens to frameCallback and calls a tick function that passes the elapsed duration between the current frame and the last frame to the ticker listener. In our case the controller.
