tween property
final
Defines the value of the TweenSequence for the interval within the animation's duration indicated by weight and this item's position in the list of items.
The value of this item can be "curved" by chaining it to a CurveTween.
For example to create a tween that eases from 0.0 to 10.0:
link
Tween<double>(begin: 0.0, end: 10.0)
.chain(CurveTween(curve: Curves.ease))
Implementation
final Animatable<T> tween;
