Operating system or device - Godot version:

It's probably a good idea for the AnimationTreePlayer to have similar signals to AnimationPlayer

[n-pigeon]

If I remember correctly it is planned to rework AnimTreePlayer?

[kubecz3k]

for now it's still valid in 3.0.2.
Workaround for this would be to

yield(get_tree().create_timer(animationPlayer.get_animation("animation_name").length), "timeout")
//animation is finished here

AnimationTreePlayer is deprecated in Godot 3.1 and will be removed in Godot 3.2. It is replaced by AnimationTree, which was written from scratch and likely fixes/deprecates this issue.

If the issue is still relevant in some form with AnimationTree in Godot 3.1, please open a new issue about it (potentially linking this one if there is relevant discussion to keep track of).
