title: How can I implement selecting only one button from group buttons in flutter
body: <p>I have added a picture of what I plan to implement. It's a group button where you can only select one option at a time. I used a package called &quot;group_button&quot; but it allows multiple selection at a time which isn't what I want.</p>
  <p>Recommend an alternative means of achieving this.</p>
