JSON Iterate Members

See more JSON Examples

Demonstrates how to loop over the immediate members of a JSON object. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final json = CkJsonObject();

  final jsonStr = '{ "id": 1, "name": "A green door", "tags": ["home", "green"], "price": 125 }';

  try {
    json.load(jsonStr);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final numMembers = json.size;
  for (var i = 0; i < numMembers; i++) {

    final name = json.nameAt(i);
    final value = json.stringAt(i);

    print('$name: $value');

    final iValue = json.intAt(i);
    print('$name as integer: $iValue');
  }

  // Note: The StringAt method returns the value as a string regardless of the type.
  // If the value is a JSON array (such as for ["home", "green"]), then the JSON encoding
  // of the entire array is returned.

  // The IntAt method returns the value as an integer.  If the value does not convert to 
  // an integer, then 0 is returned.
