Listening the changes of collection

[cemanganas]

i have nested collection.

firebaseFirestore
.collection('favourite')
.snapshots(i)
.listen((event) {
debugPrint("FAVOURITE ");
});

What i want to achieve is to have the above code listening

when i add data like this

firebaseFirestore
.collection('favourite')
.doc(authId)
.collection('list')
.add(data)

is it possible ?

Thank's
