snapshot.data!.docs; not working, The error appears on the word docs

Question

In the line of docs, an error appears. Why does this error appear? Is there an error in writing the code?

I found this same question among the questions, but without an answer, I'm still a beginner and I hope you can help me

Code:

class Messages extends StatelessWidget {
  const Messages({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return StreamBuilder(
      stream: FirebaseFirestore.instance
          .collection('chat')
          .orderBy('createdAt', descending: true)
          .snapshots(),
      builder: (context, snapshot) {
        if (snapshot.connectionState == ConnectionState.waiting) {
          return Stack(
            children: [
              Container(
                width: double.infinity,
                height: double.maxFinite,
                color: Theme.of(context).colorScheme.surface,
              ),
              const Center(
                child: CircularProgressIndicator(),
              ),
            ],
          );
        } else {
          final chatDocs = snapshot.data!.docs;
          return ListView.builder(
            //physics:  const BouncingScrollPhysics(parent: AlwaysScrollableScrollPhysics()),
            //padding: const EdgeInsets.symmetric(horizontal: 4),
            reverse: true,
            itemCount: chatDocs.length,
            itemBuilder: (context, index) => MessageBubble(
              chatDocs[index]['text'],
              chatDocs[index]['userId'] ==
                  FirebaseAuth.instance.currentUser!.uid,
              chatDocs[index]['username'],
              chatDocs[index]['userImage'],
              //key: ValueKey(chatDocs[index].id),
            ),
          );
        }
      },
    );
  }
}

Answer 1

Try snapshots.data() Firebase has different accessors for futures and streams

Answer 2

The solution was to add Query Snapshot to StreamBuilder, like this: StreamBuilder<QuerySnapshot>(
