Notes

The Icon Button makes an Icon clickable, so a user can interact with it.

Many options exist for Icon Button use, like with Icon. First, there is an extensive list of premade and labeled Icons. This list is included under the 'Icon Search' story, under the Icon tab, on Storybook, and is based on the Google Material list, which can be found at the following link:

• https://fonts.google.com/icons?selected=Material+Icons

Similarly to Icon, Icon Button offers use cases with Notification Badges, with and without a counter. Examples of these behaviors are shown under their respective Storybook stories.

The Toggleable story demonstrates an Icon Button that shows whether or not it has been clicked. In this example, the star Icon Button is filled in when clicked, and only outlined when it is unclicked. This behavior could be useful for showing an on/off function.
