聊天室不以homeScreen颤音显示

Question

我试着把聊天室的数据从火炉里拿出来并显示在我的仪表板屏幕上，

现在，我只想作为一个简单的文本接收用户列表，但它只是显示循环进度指示器

    Future<Stream<QuerySnapshot>> getChatRooms() async {
      return firestore
          .collection("chatRooms")
          .orderBy("lastMessageSendTs", descending: true)
          .where("users", arrayContains: Email)
          .snapshots();
    }
  
    chatRooms() async {
      ChatRoomsStream = await getChatRooms();
      setState(() {});
    }
  
    Widget chatRoomsList() {
      return StreamBuilder<QuerySnapshot>(
        stream: ChatRoomsStream,
        builder: (context, snapshot) {
          return snapshot.hasData
              ? ListView.builder(
                  itemCount: snapshot.data?.docs.length,
                  shrinkWrap: true,
                  itemBuilder: (context, index) {
                    DocumentSnapshot ds =
                        snapshot.data?.docs[index] as DocumentSnapshot<Object?>;
                    return Text(ds.id.replaceAll(Email, "").replaceAll("_", ""));
                  })
              : CircularProgressIndicator();
        },
      );
    }

  ),

 isSearching ? searchUserslist() : chatRoomsList(),
      ],
    ),

Widget chatRoomsList() {

                        snapshot.data?.docs[index] as DocumentSnapshot<Object?>;
                    return Text(ds.id.replaceAll(Email, "").replaceAll("_", ""));
                  })
              : CircularProgressIndicator();
