As you are using a Column Widget, to separate your 2 children you can use the mainAxisAlignment set to spaceBetween, like this:

    Column(
            mainAxisAlignment: MainAxisAlignment.spaceBetween,
            children: [...

If you want a spacific distance number, you can set a SizedBox Widget between them, and set a height that fits your need in a height property
