Answer 1

You can wrap _signInFbButton() widget with Padding and provide top padding per your requirement. Working code below:

_signInButton(),
              Padding(
              padding: EdgeInsets.only(top: 5),
              child: _signInFbButton())

Hope this answers your question.

Answer 2

Why don't you try what you have already? the SizedBox to achieve that,

_signInButton(),
 SizedBox(height: 16),//<----
_signInFbButton()
