İt is a integer and working succesfully. But i cant say samething for my map. Why its not working. How can i solve it? My controller ;

class Controller extends GetxController {


RxMap<int, ProductModel> purchaseListe= <int, ProductModel>{}.obs; 

RxList<ProductModel> foundedItem = <ProductModel>[].obs;//There are products inside
var count = 0.obs; //the working variable i am talking about


void add(int index, bool isAdded) {
    if (isAdded) {
      foundedItem[index].piece  ;
      print("tıklanan elemean indeks = $index");
      count  ;
      if (foundedItem[index].piece == 1) {
        purchaseListe.addAll({index: foundedItem[index]});
      }
    } else {
      foundedItem[index].piece--;
      print("tıklanan elemean indeks = $index");
      count--;
      if (foundedItem[index].piece == 0) {
        purchaseListe.remove(index);
      }
    }
