Cannot read property 'bool' of undefined

After installation I get this error

Also I only including the component using import AppIntro from 'react-native-app-intro';
I use react-native 0.49.3.

How can I fix this? 😭

[tyloslinger]

..It looks like the issue might be from the version of react (for react-native 0.49.3...its likely 16.0.0-beta.5)..

..the error you displaying doesn't give much info but if the issue is what i'm guessing (likely the change in how PropTypes are now referenced)..then u have to modify the react-native-swiper /src/index.js

import PropTypes from 'prop-types';
and update all React.PropTypes to PropTypes

..you might get a createClass error after that..modify same file as above with below changes..
import createReactClass from 'create-react-class'
and replace React.createClass with createReactClass

..hope this helps..

this step work for me.

1 . add
import PropTypes from 'prop-types';
in
react-native-swiper /src/index.js

2. update
   all React.PropTypes to PropTypes
   in
   react-native-swiper /src/index.js

3. add
   import createReactClass from 'create-react-class'
   in
   react-native-swiper /src/index.js

4.update
React.createClass with createReactClass
in
react-native-swiper /src/index.js

5. add
import PropTypes from 'prop-types';
and remove
PropTypes from 'react';
in
react-native-app-intro /AppIntro.js

Quick fix yarn add https://github.com/merryjs/react-native-app-intro

This is all kind of hacky not suitable for stable production app, the owner should upgrade the lib...

[Jacse]

This happens because this lib uses FuYaoDe's own fork of react-native-swiper instead of the actual (updated) library. I'm guessing because it was missing some functions.

Two solutions:

1. Update package.json switching dependency with the actual react-native-swiper
2. Update FuYaoDe's own fork to use prop-type package.

A temporary fix is going to node_modules/react-native-app-intro/node_modules/react-native-swiper/src/index.js and node_modules/react-native-app-intro/AppIntro.js and update manually to use prop-types.

@Jacse I went to https://www.npmjs.com/package/react-native-app-intro-v2, someone made the fix, this is more suitable than this kind of tricky hacks.

It's a one month issue, this is supposed to be fixed when you've a 1600+ stars software or you should mark it as not maintained anymore and give people access to fix it.

@ScreamZ I wholeheartedly agree, thanks for the link.

Hi again everyone. So I realised that the author is very unlikely to continue developing the component. For that reason I have spent the last two days making my own. It supports Android & iOS (even the iPhone X) and is pretty easy to setup. It does not support parallax yet, though.

You can take a look here

I would appreciate if anyone wants to test it out. You can install by doing:

yarn add https://github.com/Jacse/react-native-app-intro-slider.git
