title: Flutter - How to make a custom TabBar
body: <p><a href="https://i.stack.imgur.com/IpnYB.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/IpnYB.jpg" alt="My Image" /></a></p>
  <p>This is the output that I want. I am still new in flutter so can anyone let me know if there is already a widget for this kind of switch or how should I make one ??
  Also, I want the data shown below this button to change if I choose the other button but I guess that's obvious.</p>
  <p>Thanks in advance.</p>
