Tweenable class
Creates an Tweenable value which can be animated with helper functions like withTiming, withSpring, withSequence ...
You need TickerProvider in order to initialize Tweenable just like in AnimationController.
Example
....
Tweenable x = Tweenable(0.0, vsync: this)
...
x = withTiming(...)
x.value = withSpring(...)
x.value = withSequence(...)
x.value = 45.0 // no animations done here
When the value of x is set to a double (45.0), it stops all the
animations and set the position of the Tweenable to the provided value
Constructors
