cannot read property 'shape' of undefined

[awnali]

Following is my App.js

import React, { Component } from 'react';
import { Examples } from '@shoutem/ui';

export default class App extends Component {
  render() {
    return (
        <Examples />
    );
  }
}

Package.json

    "@shoutem/ui": "^0.21.3",
    "react": "16.0.0",
    "react-native": "0.50.1"

Error:
cannot read property 'shape' of undefined on iphone X,
undefined is not an object (evaluating '_react.PropTypes.shape') on iphone 7

I am getting the error as " undefined is not an object (evaluating '_react.PropTypes.shape) "

Just in case somebody else gets into this same issue, you could use my fork as a temporary fix:
yarn add "github:diegocouto/ui.git"

The PR #314 might fix most of the errors, but a lot of other libs also had to be updated in order to be able to use this package with React v16.0.0.

I work around it by patching React 16 (for the time being until the guys from shoutem would fix this)

Steps:

1. npm/yarn install prop-types create-react-class
2. Add the follwing snippet to the end of your app's node_modules/react/index.js

module.exports.PropTypes = require('prop-types');
let createClass;
Object.defineProperty(module.exports, 'createClass', {
  get: function() {
    if (!createClass) {
      createClass = require('create-react-class').bind(module.exports);
    }
    return createClass;
  }
});

Notice this patch is only valid for your local environment and everyone who clones the project and/or does 'yarn/npm install' would have to apply the patch (step 2).

Hey guys,

We've since fixed these issues with version 0.22.0 of the UI toolkit. Closing issue as resolved.
