An optional animation curve. Possible values are contained in the [AnimationCurve enumeration](../modules/_ui_enums_.animationcurve.html). Alternatively, you can pass an instance of type UIViewAnimationCurve for iOS or android.animation.TimeInterpolator for Android.

delay ​

The amount of time, in milliseconds, to delay starting the animation.

duration ​

The length of the animation in milliseconds. The default duration is 300 milliseconds.

isForwards ​

Determines whether the animation values will be applied on the animated object after the animation finishes.

isReverse ​

If true the animation will be played backwards.

iterations ​

Specifies how many times the animation should be played. Default is 1. iOS animations support fractional iterations, i.e. 1.5. To repeat an animation infinitely, use Number.POSITIVE_INFINITY

keyframes ​

Return animation keyframes.
