Tween.animate() throws exception for Animation<Offset> in slow mode #13812
Description
Steps to Reproduce
Use a FractionalOffsetTween.animate() for position parameter in SlideTransition
new SlideTransition(
position: new FractionalOffsetTween(
begin: FractionalOffset.topRight,
end: FractionalOffset.topLeft,
).animate(
new CurvedAnimation(
parent: animation,
curve: Curves.ease,
)
),
...
