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 have information there : http://cogitas.net/parse-json-dart-flutter/

Example from the page :

void _parseJsonForCrossword(String jsonString) {
Map decoded = JSON.decode(jsonString);

String name = decoded['name'];
 print(name);

 int id = decoded['id'];
 print(id.toString());

 for (var word in decoded['across']) {
   print(word['number'].toString());
   print(word['word']);
 }
}

Answer 2

You could use the following snippet:

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