    actually the function named _getDataRow is a template for the actual objects which will be invoked in the page, so you need to call it and use any state management to update the content, I suggest to use bloc or provider

    While a state management using for example BLoC should be preferred,
    for quick testing you can use the setState argument inside of a StatefulWidget like this…

        setState(() {
       results = _getDataRow(someIndex, newData);
    });
