how to sum data from json object ? flutter-CodePudding

i am building an shopping and i am new to flutter i am calling data from my server by below method:

 Future getCartData() async {
 print("this is the token mytoken");
 String url = 'https://myurl.com/apis/getCartItems';
 http.Response response = await http.post(Uri.parse(url),
    headers: {
      'Authorization': "token mytoken",
      "Content-Type": "application/json",
    },
    body: json.encode({
      "username": "admin",
    }));
 print(response.body);
 var data = json.decode(response.body);
 print("cart data recieved :");
 print(data.length);
 return data;

}

and my json data looks like this:

{  {
   "id":"8",
   "title":"art-fusion gold",
   "itemimage":"/media/10.jpg",
   "price":3499.0
    },
    {
   "id":"9",
   "title":"ruby gold",
   "itemimage":"/media/11.jpg",
   "price":3699.0
   }
 }

and i am accessing every item details in future builder as:

list[index]['title']

everything working great i just want to add prices and store it into a variable so that i can show my users that what there total price is but i dont know how to ad this "price" variable from json.

can someone please help thanks in advance <3

CodePudding user response：

var totalPrice = 0;

and then in your loop

totalPrice = totalPrice   list[index]['price'];

Then print or use this totalPrice variable.

But it is not a good way to access json data. Try to make data model/pojo class and then by using model/pojo class access data.
