tried to create list...using data from firebase (stream builder) but got an error

Question

error is:

Closure call with mismatched arguments: function '[]'
Receiver: Closure: () => Map<String, dynamic> from Function 'data':.
Tried calling: []("quizImgUrl")
Found: []() => Map<String, dynamic>

trying to get image url in my code from:

ListView.builder(
                  itemCount: snapshot.data.documents.length,
                  itemBuilder: (context, index) {
                    return QuizTile(
                      imgUrl: snapshot.data.documents[index].data["quizImgUrl"],
                      desc: snapshot.data.documents[index].data["quizDesc"],
                      title: snapshot.data.documents[index].data["quizTitle"],
                    );
                  });

getting data from firebase as:

getQuizData() async {
    return await Firestore.instance.collection("Quiz").snapshots();
  }

There is a get method for accessing the data in firestore plugin like snapshot.data.documents[index].data.get("quizImgUrl"). — Shahryar Rafique

Thank you @ShahryarRafique for your suggestions. I can access the data using: snapshot.data.document[index].get("quizImgUrl") — Beenod

user snapshot.data.docs instead. They had many breaking changes in the latest updates to firebase packages.
