componentelementType-

The component used for the root node. Either a string to use a HTML element or a component.

disabledboolfalse

If true, the component is disabled.

focusVisibleClassNamestring-

This prop can help identify which element has keyboard focus. The class name will be applied when the element gains the focus through keyboard interaction. It's a polyfill for the CSS :focus-visible selector. The rationale for using this feature is explained here. A polyfill can be used to apply a focus-visible class to other components if needed.

loadingboolfalse

If true, the loading indicator is shown and the icon button becomes disabled.

loadingIndicatornode<CircularProgress />

The node should contain an element with role="progressbar" with an accessible name. By default we render a CircularProgress that is labelled by the button itself.
