In this way, you can access the data by giving the names collection and field.

try this method...

Future<void> getAllData() async {
   List<Productmodel> productModelList = [];

   var data = await FirebaseFirestore.instance.collection("product").doc('CWvaDGh5ZaCznGtLnq6A').get();
   List dataList = data.data()?['product'];
   
   for (var element in dataList) {
     productModelList.add(Productmodel.fromJson(element));
   }

  print('productModelList : ${productModelList.toList()}');
}
