Unsubscribing to firebase firestore's updates listener

[aseelmqannasa]

Hello,
what is the best way to unsubscribe to firestore.collection().onSnapshot() on logout?

Note: I am using multiple stores and I am using a listener to updates in every store, but I want to unsubscribe to all listeners on logout.
