Xamarin Plugin.CloudFirestone - Stop Realtime update

Issue

I can successfully use firebase realtime with xamarin using Plugin.CloudFirestone.

I use the listener this way:

CrossCloudFirestore.Current.Instance.Collection("yourcollection")
                       .Document("yourdocument")
                       .AddSnapshotListener((snapshot, error) =>
                       {
                           ...
                       });

But when the user logout I need to stop listening. Does anyone know how to do it? I've read the official material but I couldn't get any information about it. thanks!

Solution

As the documentation on detaching a listener shows, you can call Stop() on the object that is returned when you attach the listener:

DocumentReference query = db.Collection("yourcollection")..Document("yourdocument")

ListenerRegistration listener = query.Listen(snapshot => {
  foreach (DocumentSnapshot documentSnapshot in snapshot.Documents) {
    Debug.Log(documentSnapshot.Id);
  }
});

And then later:

listener.Stop();

This call will stop the listener from receiving further updates.
