Fetch data from Firestore Document using StreamBuilder – Flutter

In my Flutter app, I’m trying to get the data from a Document in Firestore. Here’s the data I want to get :

Firestore document’s data

I need to fetch that url from the Document. So far, when I needed to fetch data from a collection, I used a Streambuilder. But here I need to fetch data from a document, so I get this error message :

late Stream<DocumentSnapshot<Map<String, dynamic>>>? personnalData =
      FirebaseFirestore.instance
          .collection('Decembre')
          .doc(uid)
          .collection('Docs')
          .doc('test')
          .snapshots();

   StreamBuilder<QuerySnapshot>(
              stream: personnalData, // Error: The argument type 'Stream<DocumentSnapshot<Map<String, dynamic>>>?' can't be assigned to the parameter type 'Stream<QuerySnapshot<Map<String, dynamic>>>?'.
              builder: (BuildContext context,
                  AsyncSnapshot<QuerySnapshot> snapshot) {
                if (snapshot.hasError) {
                  return const Text('Something went wrong');
                }
                if (snapshot.connectionState == ConnectionState.waiting) {
                  return Center(child: CircularProgressIndicator());
                }
                return Stack(
                  children: snapshot.data!.docs
                      .map((DocumentSnapshot document) {
                        Map<String, dynamic> data =
                            document.data()! as Map<String, dynamic>;

                );
              },
            ),

Any suggestions ?
