title: Flutter dart: How to separate the space between Text and TextField and also bring together RadioListTile?
body: <p>I'm learning Flutter. I have a problem (see image below). I would like to separate the space between Text "sex" and TextField "name". I would also like to bring together RadioListTile, they are very separate. Is it possible to do that? Follow my code</p>
