useAnimationController function

AnimationController useAnimationController(
  1. {Duration? duration,
  2. Duration? reverseDuration,
  3. String? debugLabel,
  4. double initialValue = 0,
  5. double lowerBound = 0,
  6. double upperBound = 1,
  7. TickerProvider? vsync,
  8. AnimationBehavior animationBehavior = AnimationBehavior.normal,
  9. List<Object?>? keys}

Creates an AnimationController and automatically disposes it when necessary.

If no vsync is provided, the TickerProvider is implicitly obtained using useSingleTickerProvider. If a vsync is specified, changing the instance of vsync will result in a call to AnimationController.resync. It is not possible to switch between implicit and explicit vsync.

Changing the duration parameter automatically updates the AnimationController.duration.

initialValue, lowerBound, upperBound and debugLabel are ignored after the first call.
