How to remove all listeners from Firebase in C#?

Question

In my project I've got quite a nice amount of listeners set to listen for any changes in the realtime database. For some reason those listeners stay even if I reload the scene using

Application.LoadLevel("mainScene");

It would be quite a lot of hassle to remove each listener individually using

FirebaseDatabase.DefaultInstance
    .RootReference
    .Child("sub path 1")
    .Child("sub path 2")
    .ValueChanged -= SomeFunction;

FirebaseDatabase.DefaultInstance
    .RootReference
    .Child("path")
    .ValueChanged -= AnotherFunction;

Is there a way to remove listeners from all paths?

On most platforms the Firebase SDK has a call to remove all handlers from a location. But from a quick scan such a method doesn't seem to be available in the Unity SDK. If might be worth filing a feature request.

Note that even if such a method exists in C#, you'll still need to call it on each DatabaseReference your code uses.

C# has a way to do this, see https://stackoverflow.com/questions/36084469/how-to-remove-all-eventhandler . – stewartmiles May 30 '17 at 20:51
Thanks Stewart! I'll close this as a duplicate of that question. – Frank van Puffelen May 30 '17 at 20:54
After a chat with Ben we can't do this from outside of the class unfortunately. So it sounds like we'll need to add some way of ditching event handlers as part of the API. We still need to figure this out unfortunately. – stewartmiles May 31 '17 at 21:17
OK, I reopened the question. My original answer was correct then. :-) – Frank van Puffelen May 31 '17 at 21:33
