Flutter: JSON Loop

Question

I have a Json parsing project in Flutter and the Json is as follows:

{
  \"Dependents\":[
      {
        \"Name\": \"Kim\",
        \"Relationship\": \"Pare         


        

Answer 1

You could use the following snippet:

  void iterateJson(String jsonStr) {
    Map myMap = json.decode(jsonStr);
    List entitlements = myMap["Dependents"][0]["Entitlements"];
    entitlements.forEach((entitlement) {
      (entitlement as Map).forEach((key, value) {
        print(key);
        (value as Map).forEach((key2, value2) {
          print(key2);
          print(value2);
        });
      });
    });
  }

Although you could possibly simplify a little the 'entitlements' field if you don't care about the order by removing the list and leaving just one map:

"Entitlements": {
              "GP": {
                "Entitlement": "10000",
                "Utilisation": "500",
                "Balance": "9500"
              },
              "OPS": {
                "Entitlement": "10000",
                "Utilisation": "500",
                "Balance": "9500"
              },
              "IP": {
                "Entitlement": "10000",
                "Utilisation": "500",
                "Balance": "9500"
              }
            }
