[Question] - How to restart animation? about flutter_animate HOT 2 CLOSED

Hi @definev - glad you're liking the library! Currently to restart the animation, you can use its controller, which you can get from either onInit or onComplete:

foo.animate(
  onInit: (controller) => _animController = controller // save off the controller
).fade().slide() // or whatever.

// then later, restart the animation:
_animController.forward(0)

I believe (untested) you should also be able to restart the animation a bit more declaratively by assigning a new unique key to the animation when the view rebuilds.

foo.animate(
  key: myKey // change the key when you want it to restart.
).fade().slide()

In the future, I'd like to add a bit more state-awareness onto Animate so that this is a bit easier to control.

Thank you, I like the key approach, it works but I am using AnimatedContainer in the child of Animate widget. Unfortunately, the side effect destroys the state of AnimatedContainer :( But I think I don't need AnimatedContainer, I can also calculate the size of the grid yourself, thank you for your answer! Love your package!
