When I do

class MyC extends React.Component { this.someRef = React.createRef<HTMLButtonElement>(); render() { return ( <IconButton buttonRef={this.someRef} /> ); } }

it works but the following warning is issued

Warning: Failed prop type: Invalid prop `buttonRef` of type `object` supplied to `ButtonBase`, expected `function`. in ButtonBase (created by WithStyles(ButtonBase)) 

• I have searched the issues of this repository and believe that this is not a duplicate.
