if you are using StreamBuilder then you must use this line of code

  StreamBuilder(
                  stream: FirebaseFirestore.instance.collection("Tooth")
                  .orderBy("date", descending: false).snapshots() ,
                
                  builder: (BuildContext context, AsyncSnapshot snapshot){
                 
                    if(snapshot.hasData)
                    {
                      return ListView.builder(
                        itemCount: snapshot.data.docs.length,
                          padding: const EdgeInsets.only( top: 20.0),
                        itemBuilder: (BuildContext context, int index) {
                           DocumentSnapshot ds = snapshot.data.docs[index];
 },
                      );
                    }
                   
                  },
                ),
