  ]);
 dynamic response;
 
 @override
   Widget build(BuildContext context) {
     return new Scaffold(
       appBar: new AppBar(
         title: new Text(widget.title),
       ),
       body: new SingleChildScrollView(
         child: new Container(
           child: new Column(children: <Widget>[
             new CoreForm(
               form: form,
               onChanged: (dynamic response) {
                 this.response = response;
               },
             ),
             new RaisedButton(
                 child: new Text('Send'),
                 onPressed: () {
                   print(this.response.toString());
                 })
           ]),
         ),
       ),
     );
   }

When there is a change in the form, the (dynamic response;) is updated,

               onChanged: (dynamic response) {
                 this.response = response;
               },

when text is added to the TextField, add field called response

// initial form_send_email
[{"type":"Input","title":"Subject","placeholder":"Subject"},{"type":"TareaText","title":"Message","placeholder":"Content"}]

// add text (hi) in TextField Message, update dynamic response; and add field called response
[{type: Input, title: Subject, placeholder: Subject}, {type: TareaText, title: Message, placeholder: Content, response: hi }]
