importing PropTypes from react has been deprecated in React 16, I would check all the libraries you're using in your package.json for any issues on their github pages. — MattyK14

This is caused by an component issue, to fix it go to the component .js and make this changes

import React,{
    PropTypes
} from 'react';

to

import React from 'react';
import PropTypes from 'prop-types';

them find all View.propTypes.style and change to ViewPropTypes.style

can you give me the path where i can find this file - component.js ?

what i mean is there's a component in your application who have an proptypes issue, you need to debug it to find, i recommend search in your application for .js files with View.propTypes.style
