Try:
userList.add(kako.User.fromMap(querySnapshot.docs[i].data() as Map<String, dynamic>))

I want to fetch all users except the current user from the Firestore collections, but I've got this error:
The argument type 'QueryDocumentSnapshot<Object?>' can't be assigned to the parameter type 'Map<String, dynamic>').
A fragment of my code:
Future <List<kako.User>> fetchAllUsers(User currentUser) async { List<kako.User> userList = List<kako.User>.generate(20, (index)=>kako.User()); QuerySnapshot querySnapshot = await fireStore.collection("users").get(); for (var i = 0; i < querySnapshot.docs.length ; i++) { if(querySnapshot.docs[i].id != currentUser.uid){ userList.add(kako.User.fromMap(querySnapshot.docs[i].data())); } } return userList; }
querySnapshot.docs[i].data()
is underlined with red
