Dart

import 'package:chilkat/chilkat.dart';

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

  // The following code builds the following JSON, which contains both an empty array and empty object:

  // 	{
  // 	  "abc": {
  // 	    "xyz": [
  // 	      {
  // 	        "Name": "myName",
  // 	        "Description": "description",
  // 	        "ScheduleDefinition": "schedule definition",
  // 	        "ExceptionScheduleDefinition": "",
  // 	        "Attribute": [
  // 	        ],
  // 	        "SomeEmptyObject": {},
  // 	        "token": "token"
  // 	      }
  // 	    ]
  // 	  }
  // 	}

  json.updateString('abc.xyz[0].Name', 'myName');
  json.updateString('abc.xyz[0].Description', 'description');
  json.updateString('abc.xyz[0].ScheduleDefinition', 'schedule definition');
  json.updateString('abc.xyz[0].ExceptionScheduleDefinition', '');
  json.updateNewArray('abc.xyz[0].Attribute');
  json.updateNewObject('abc.xyz[0].SomeEmptyObject');
  json.updateString('abc.xyz[0].token', 'token');

  json.emitCompact = false;
  print(json.emit());
