React native android Undefined is not function

React native android:

When I am navigating from one screen to next screen

undefined is not a function (evaluating '(0, _reactNavigation.StackNavigator)({ SettingScreen: { screen: _settings.default }, HomeScreen: { screen: _Home.default } })')

App.js

import React, {Component} from 'react';
import { AppRegistry} from 'react-native';
import { Button } from 'react-native';
import {Navigation} from 'react-native'
import { StackNavigator } from 'react-navigation';

import Settings from './screens/Settings';
import Home from './screens/Home';

const AppNavigator = StackNavigator({
  SettingScreen: { screen: Settings },
  HomeScreen: { screen: Home }
});

export default class App extends Component<Props> {

    render() {
    return (
        <AppNavigator />
    );
  }
}

Setting.js

import React, { Component } from 'react';
import { View, Text, Button } from 'react-native';

export class Settings extends Component {
  render() {
    return (
      <View>
        <Text>This is the Settings screen</Text>
        <Button onPress={() => this.props.navigation.navigate('HomeScreen')} title="Home"/>
      </View>
    )
  }
};

export default Settings;

Home.js

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

export class Home extends Component {
  render() {
    return (
      <View>
        <Text>This is the home screen</Text>
      </View>
    )
  }
}

export default Home

  1. Update your App.js to the below.

    const App = createStackNavigator({ Home: HomeScreen, Profile: ProfileScreen, });

    export default createAppContainer(App);

  2. Remove the line export default Settings;

  3. Remove the line export default Home;
