@ashemag , I'm using Next.js and encountering this issue for the first time also. In my specific app, if I navigate directly to the page with a `MathComponent` element, then...

Same problem. ``` "react": "^16.1.1", "react-native": "0.50.3", "react-native-material-design": "^0.3.7", "react-native-vector-icons": "^4.4.2", ``` `React.PropTypes` has been deprecated as PropTypes has been moved out of the standard library since React v15.5. https://reactjs.org/warnings/dont-call-proptypes.html...

From the README: > This library is unmaintained. Please use at your own risk. I'd recommend switching to `react-native-elements` instead.
