# addAnimationCompletion(criteria:_:)

Adds a completion to run when the animations created with this
transaction are all complete.

```
mutating func addAnimationCompletion(criteria: AnimationCompletionCriteria = .logicallyComplete, _ completion: @escaping () -> Void)
```

## Discussion

The completion callback will always be fired exactly one time. If no
animations are created by the changes in `body`, then the callback will
be called immediately after `body`.
