html - The best way to parse a JSON in Dart

Question

I'm trying to load a json file from a URL and parse it within Dart. So I had tried the following code as suggested from some links when I google for it:

   HttpRequest.getString("hellknight2.js").then((response)
   {
     var model = new JSON.parse(response);
   });

However, it seems to not work anymore on Dart SDK version 0.4.3.5_r20602. What is the current best way to get a Json file mapped to an object in Dart?

Answer 1

Simply use json of the dart:convert package. Here is an example :

import 'dart:convert';

main() {
  final myJsonAsString = '{"a": 1, "b": "c"}';
  final decoded = json.decode(myJsonAsString);
  ....
}
