title: Using setState with StatelessWidget
body: <p>Is there a way to use setState with StatelessWidget?
  I know that I could be used with StatefulWidget and using a State, but I don't know if there's a way to use it with StatelessWidget.</p>
  
  <p>I think that's a direct question and it doesn't need code to be shown.</p>
  
  <p>If you could help me, I will appreciate it.</p>
