How to add a button in React Native?

Question

I´m confused with this whole \"no CSS\" thing, but I understand why it\'s beneficial. All I want to do is place a button in the middle of the screen but I don\'t understand how

Answer 1

export default class Login extends React.Component {
  barcodeAction = () => {
    this.props.navigation.navigate('BarCodeScanner')
  }

  cleverTapAction = () => {
    this.props.navigation.navigate('CleverTapApp')
  }
} 

render() {
    return (
      
        
          
        
        
          
        
        
          
          
        
      
    );
  }
}

const styles = StyleSheet.create({
  container: {
   flex: 1,
   justifyContent: 'center',
  },
  buttonContainer: {
    margin: 20
  },
  alternativeLayoutButtonContainer: {
    margin: 20,
    flexDirection: 'row',
    justifyContent: 'space-between'
  }
});
