React Native: 'undefined is not an object (evaluating '_react3.PropTypes.bool')

I have recently tried to export my react native project to expo. Although, it had updated react-native, and now get an error of 'undefined is not an object (evaluating '_react3.PropTypes.bool')'

Error message

I have looked to solve this and found that I need to import proptypes - import PropTypes from 'prop-types'; which ive added in all my scripts, still the error message persists. Moreover, I dont use any proptypes, so I dont get why i would get this error in the first place.

If you would like to take a look at the proj, please do - https://github.com/rasselll/probs

The error is clearly mentioned in the log and is due to react-native-view-transformer library.

The library still uses the PropTypes package from react. Since your react version is higher that v15.5 therefore it is giving an error.

Here's a file from the package that is still using the deprecated version of propTypes
