react-native-elements: icons throw Invariant Violation error - reactjs

Question

I'm new to react native and I face a problem I have no idea how to solve.
I created and started a new project as follows:
create-react-native-app ProjectName
cd ProjectName
yarn add react-native-elements#beta
npm start
The package.json looks like this:
{
"name": "test",
"version": "0.1.0",
"private": true,
"devDependencies": {
"jest-expo": "25.0.0",
"react-native-scripts": "1.11.1",
"react-test-renderer": "16.2.0"
},
"main": "./node_modules/react-native-scripts/build/bin/crna-entry.js",
"scripts": {
"start": "react-native-scripts start",
"eject": "react-native-scripts eject",
"android": "react-native-scripts android",
"ios": "react-native-scripts ios",
"test": "node node_modules/jest/bin/jest.js"
},
"jest": {
"preset": "jest-expo"
},
"dependencies": {
"expo": "^25.0.0",
"react": "16.2.0",
"react-native": "0.52.0",
"react-native-elements": "^1.0.0-beta3"
}
}
Then I wanted to insert a button with an icon like this:
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import { Button } from 'react-native-elements';
export default class App extends React.Component {
render() {
return (
<View style={styles.container}>
<Text>Open up App.js to start working on your app!</Text>
<Text>Changes you make will automatically reload.</Text>
<Text>Shake your phone to open the developer menu.</Text>
<Button
raised
icon={{ name: 'cached' }}
title='BUTTON WITH ICON' />
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center',
},
});
Unfortunately, I get this error message:
error message on iphone
Does anyone have a hint how I can make the icons work? I already tried to add the vector-icons with 'yarn add react-native-vector-icons', although I do have a create-react-native project, but that did'nt work neither.
Thank you!

Answer 1

It should be this way:
import { Button } from 'react-native-elements';
import Icon from 'react-native-vector-icons/FontAwesome';
...
<Button
icon={
<Icon
name='arrow-right'
size={15}
color='white'
/>
}
title='BUTTON WITH ICON'
/>
