How to add Entry text fields dynamically

I am trying to make a program that adds text fields (or Entry) every time OnStepperValueChanged has a new value

For instance when users press the ' + ' on the Stepper once, one text field will appear. When users press twice, two text fields will appear and so on.

Does anyone know how to accomplish this?

Thanks
