Future Request feature alt text for Button Icon

My accessibility tests are indicating that alt text for the button icons would be better. I don't see thatis a current option.

Hi 
  We are considering adding alt text for button icon in the future as it might take some extra time to finish. We appreciate your patience and understanding. Thank you

We will release a new version with the option to add alt text for button icon, please check again with the latest package. Thanks.
