CodePudding user response：

You should extends from GetxController in the controller.

So just change GetxService to GetxController in the controller.

Please check below sample :

class PopularProductController extends GetxController {
  final PopularProductRepo popularProductRepo;
  PopularProductController({required this.popularProductRepo});
  List<dynamic> _popularProductList = [];
  List<dynamic> get popularProductList => _popularProductList;
  Future<void> getPopularProductList() async {
    Response response = await popularProductRepo.getPopularProductlist();
    if (response.statusCode == 200) {
      _popularProductList = [];
      print('product list');

      _popularProductList.addAll(Product.fromJson(response.body).products);
      print(_popularProductList);
    }
  }
}
