Hi @jiya1

Can you post your app code for me to rate?

Is the server configured for Livequery in the "post" class?

The code below is an example and is working:

    QueryBuilder<ParseObject> query =
        QueryBuilder<ParseObject>(ParseObject('TestAPI'))
          ..whereEqualTo('intNumber', 1);

    //LiveQuery liveQuery = LiveQuery();
    await liveQuery.subscribe(query);

    liveQuery.on(LiveQueryEvent.update, (value) {
      print('*** UPDATE ***: ${DateTime.now().toString()}\n $value');
      print((value as ParseObject).objectId);
      print((value as ParseObject).updatedAt);
      print((value as ParseObject).createdAt);
      print((value as ParseObject).get('objectId'));
      print((value as ParseObject).get('updatedAt'));
      print((value as ParseObject).get('createdAt'));
    });

    liveQuery.on(LiveQueryEvent.delete, (value) {
      print('*** DELETE ***: ${DateTime.now().toString()}\n $value');
      print((value as ParseObject).objectId);
      print((value as ParseObject).updatedAt);
      print((value as ParseObject).createdAt);
      print((value as ParseObject).get('objectId'));
      print((value as ParseObject).get('updatedAt'));
      print((value as ParseObject).get('createdAt'));
    });

    liveQuery.on(LiveQueryEvent.create, (value) {
      print('*** CREATE ***: ${DateTime.now().toString()}\n $value ');
      print((value as ParseObject).objectId);
      print((value as ParseObject).updatedAt);
      print((value as ParseObject).createdAt);
      print((value as ParseObject).get('objectId'));
      print((value as ParseObject).get('updatedAt'));
      print((value as ParseObject).get('createdAt'));
    });

    liveQuery.on(LiveQueryEvent.leave, (value) {
      print('*** LEAVE ***: ${DateTime.now().toString()}\n $value ');
      print((value as ParseObject).objectId);
      print((value as ParseObject).updatedAt);
      print((value as ParseObject).createdAt);
      print((value as ParseObject).get('objectId'));
      print((value as ParseObject).get('updatedAt'));
      print((value as ParseObject).get('createdAt'));
    });

    liveQuery.on(LiveQueryEvent.enter, (value) {
      print('*** LEAVE ***: ${DateTime.now().toString()}\n $value ');
      print((value as ParseObject).objectId);
      print((value as ParseObject).updatedAt);
      print((value as ParseObject).createdAt);
      print((value as ParseObject).get('objectId'));
      print((value as ParseObject).get('updatedAt'));
      print((value as ParseObject).get('createdAt'));
    });

    liveQuery.on(LiveQueryEvent.error, (value) {
      print('*** ERROR ***: ${DateTime.now().toString()}\n $value ');
      if (value is ParseObject) {
        print((value as ParseObject).objectId);
        print((value as ParseObject).updatedAt);
        print((value as ParseObject).createdAt);
        print((value as ParseObject).get('objectId'));
        print((value as ParseObject).get('updatedAt'));
        print((value as ParseObject).get('createdAt'));
      }
    });

Sorry .. it was an issue from the server side ..

It dosn't work.
While I use :
LiveQuery liveQuery = LiveQuery();
await liveQuery.subscribe(query);

It will bring me this error:
NoSuchMethodError (NoSuchMethodError: The method 'contains' was called on null.

in the parse_live_query.dart file, it seems the object was not exist.
