Comment by @HawkDanny:

It is important to note that function called by an animation event is allowed to have a float, string, int, object reference, or an AnimationEvent object as its parameter. However, it cannot have a bool as a parameter. Any function with a bool as a parameter will simply not show up in the dropdown of the available functions on the animation event.

Comment by @tpryde:

A small gotcha when blending animations is events wont trigger if the animations' blend weight is 50% or less. This is commonly noticed when adding an OnComplete event on the last frame. Consider making a custom StateMachineBehaviour or a coroutine to wait the duration of the animation clip.

🛠️ Practical Use
You’d write your function to accept an AnimationEvent as its parameter, and then extract the values you need from it. For example:

public void HandleEvent(AnimationEvent evt) {
    Debug.Log("Float value: " + evt.floatParameter);
    Debug.Log("String value: " + evt.stringParameter);
    // and so on...
}

This lets you pass richer data to your animation-triggered functions without breaking Unity’s one-parameter rule.
