React-native-chart-kit: cannot run on iOS or android(expo)

Created on 13 Mar 2020 · 4Comments · Source: indiespirit/react-native-chart-kit

when I tried to run the following example on Expo

import React from 'react'
import { LineChart,} from "react-native-chart-kit";
import {View,Text,Dimensions} from 'react-native'

class AgeChart extends React.PureComponent {
    render() {

        return (
           <View>
  <Text>Bezier Line Chart</Text>
  <LineChart
    data={{
      labels: ["January", "February", "March", "April", "May", "June"],
      datasets: [
        {
          data: [
            Math.random() * 100,
            Math.random() * 100,
            Math.random() * 100,
            Math.random() * 100,
            Math.random() * 100,
            Math.random() * 100
          ]
        }
      ]
    }}
    width={Dimensions.get("window").width} // from react-native
    height={220}
    yAxisLabel="$"
    yAxisSuffix="k"
    yAxisInterval={1} // optional, defaults to 1
    chartConfig={{
      backgroundColor: "#e26a00",
      backgroundGradientFrom: "#fb8c00",
      backgroundGradientTo: "#ffa726",
      decimalPlaces: 2, // optional, defaults to 2dp
      color: (opacity = 1) => `rgba(255, 255, 255, ${opacity})`,
      labelColor: (opacity = 1) => `rgba(255, 255, 255, ${opacity})`,
      style: {
        borderRadius: 16
      },
      propsForDots: {
        r: "6",
        strokeWidth: "2",
        stroke: "#ffa726"
      }
    }}
    bezier
    style={{
      marginVertical: 8,
      borderRadius: 16
    }}
  />
</View>
        )
    }
}

export default AgeChart

I keep getting this error
_Exception thrown while executing UI block:- [__NSCFNumber firstObject]: unrecognised selector sent to instance 0xb8de0cb5768fff3_ for IOS

and for Android
_Error while updating property 'stroke' of a view managed by RNSVGLine
