react native using sha256

I'm trying to use this react-native library to do sha256 hashing. Here is my code:

import React, {Component} from 'react'
import { AppRegistry, Text, View} from 'react-native'
import {sha256} from 'react-native-sha256'

export default class CyrptoTest extends Component {
    constructor(props){
        super(props)
    }

    componentDidMount(){
        sha256("test").then(hash => {
            console.log(hash)
        })
    }

    render(){
            return(
                <View style={{padding:30}}>
                    <Text>this is CryptoTest 1</Text>
                </View>
            )
    }
}

I am getting this error: undefined is not an object (evaluating 'sha256lib.sha256')
I do not know why this is or how to fix this, any help is appreciated, thanks

PS: Before I did any of this I first ran this in the command line:

yarn add react-native-sha256
react-native link

Also to run the app in my emulator on my mac I do this:

react-native start
react-native run-ios

I had the same problem, in my case I was using the react native cli debug server host & port for device, it was solved with a ./gradlew clean and recompiling the app on the phone.
