import error

[radicalization]

after installation npm install react-native-charts --save and import
import {BarChart} from 'react-native-charts';
i am getting error:

i saw the pr with importing PropTypes from 'prop-types' not from 'react' maybe that would solve it

then problem is that react.proptypes is deprecated, I just figured this out a while ago and managed to fix it apparently,

first install the prop-types library using:

npm install prop-types --save

then go to node_modules/react-native-charts/src

when you get there open the components folder and the constants folder and open every file(they are like 9 files in total)

if you read the imports you will notice that most of these files are using proptypes from react-native
import { PropTypes } from 'react';
so thats where the error comes in, you should have to remove that import and then import proptypes from the library you just installed like this
import PropTypes from 'prop-types';

also check at the beggining of these components for something like this

static propTypes = {
destinationValueScale: PropTypes.number.isRequired,
fillColor: PropTypes.string.isRequired,
horizontal: PropTypes.bool,
initialValueScale: PropTypes.number.isRequired,
maxValue: PropTypes.number.isRequired,
value: PropTypes.number.isRequired,
valueScaleSpringFriction: PropTypes.number.isRequired,
style: View.propTypes.style,
}

if you dont fix this, you will have other error because View.propTypes is not the way how the prop-types library handles the objects, instead, the library handles that with PropTypes.object , basically, everywhere you find View.propTypes change it for PropTypes.object, so the resulting object will be something like this

static propTypes = {
destinationValueScale: PropTypes.number.isRequired,
fillColor: PropTypes.string.isRequired,
horizontal: PropTypes.bool,
initialValueScale: PropTypes.number.isRequired,
maxValue: PropTypes.number.isRequired,
style: PropTypes.object.styles,
value: PropTypes.number.isRequired,
valueScaleSpringFriction: PropTypes.number.isRequired,
}

I think thats all I did to solve it. just check those files and make the changes and load the app again
