Why am I getting Typeerror super expression must either be null or a function?

So I just started learning React Native last week to try and learn to develop apps. I've been learning from a Udemy course and it has been going pretty well until I tried to create a new component. I've rewatched the lesson 3 times to try and find my mistake but I can't seem to see a difference between code. Please forgive my amateur mistake wherever it is. The main app.js file contains this:

import React from 'react';
import { StyleSheet, Text, View, Platform, Image, ImageBackground } from 'react-native';
import {Button} from 'native-base';
import Landing from './src/Landing'
import { render } from 'react-dom';

var myBackground = require('./assets/icons/landing.jpg');

export default class App extends React.Component() {
  render() {
  return (
    <View style={styles.container}>
      <Landing />
    </View>
  );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    marginTop: Platform.OS === "android" ? 50 : 0
  },
});

and my component code is this:

import React from 'react';
import {View, Text, Image, StyleSheet} from 'react-native';
import {Button} from 'native-base';

var myBackground = require('../assets/icons/landing.jpg');

class Landing extends React.Component {
    render() {
        return(
            <View>
                <ImageBackground style={ styles.imgBackground } source={myBackground}>
                    <View style={styles.viewStyle}>
                    <Text style={styles.titleStyle}>Welcome to PokeSearch</Text>
                    <Button block={true} style={styles.buttonStyle} onPress={()=>{}}>
                        <Text style={styles.buttonText}>Start Searching for Pokemon!</Text>
                    </Button>
                    </View>
                </ImageBackground>
            </View>
        )
    }
}

const styles = StyleSheet.create({
    container: {
      flex: 1,
      marginTop: Platform.OS === "android" ? 50 : 0
    },
    imgBackground: {
      width: '100%',
      height: '100%',
      flex: 1 
  },
  viewStyle: {
    flex: 1,
    flexDirection: 'column',
    justifyContent: "center",
    alignItems: "center"
  },
  titleStyle: {
    fontSize: 30,
    color: 'red',
    alignItems: 'center',
  },
  buttonStyle: {
    margin: 10
  },
  buttonText: {
    color: 'red'
  },
  });


export default Landing;

Any help would be greatly appreciated, I can't seem to find where I am going wrong... Here is the full error in the emulator: Thanks in advance!
