Flutter Firestore listen on Stream

Question

I am using this code to listen on document changes:

Stream stream = db.doc(docRef.path).snapshots();

But I can't find a way to unsubscribe this listener from Firebase. I checked theStream class. Is this happening by default if I close the app? I found examples for this in other languages here but I can't figure out how to do this in dart.

Any advice? Thanks a lot!

Answer 1

You don't unsubscribe from Stream . You unsubscribe from StreamSubscription using the cancel() method.

So first start listening to your stream using .listen() on the stream, this will return you StreamSubscription which you can then cancel.
