'PopularProductController' doesn't conform to the bound 'GetxController' of the type parameter 'T'
存在代码。有人帮我解决这个问题。我无法解决这个问题。这种类型的问题我第一次遇到所以我无法解决。请有人帮助我
Widget build(BuildContext context) {
print("current height is " + MediaQuery.of(context).size.height.toString());
print("current width is " + MediaQuery.of(context).size.width.toString());
return Column(
children: [
//slider section
GetBuilder<PopularProductController>(builder:(popularproducts){
return Container(
// color: Colors.blue,
height: Dimentions.pageView,
child: PageView.builder(
controller: pageController,
itemCount: 5,
itemBuilder: (context, position) {
return _buildPageItem(position);
},
),
);
第二个代码是控制器部分代码。有人帮我解决这个问题。我无法解决这个问题。这种类型的问题我第一次遇到所以我无法解决。请有人帮助我。
import 'package:fooddeliver/data/repository/popular_product_repo.dart';
import 'package:fooddeliver/modals/products_modal.dart';
import 'package:get/get.dart';
class PopularProductController extends GetxService {
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);
}
}
}
您应该在控制器中从 GetxController
扩展。
所以只需在控制器中将GetxService
更改为GetxController
即可。
请检查以下示例:
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);
}
}
}
