Usage

Basic example

No configuration	showSkipButton	bottomButton and showSkipButton

import React from 'react';
import { StyleSheet } from 'react-native';
import AppIntro from 'rn-app-intro-screen';

const styles = StyleSheet.create({
  image: {
    width: 320,
    height: 320,
  }
});

const slides = [
  {
    key: 'somethun',
    title: 'Title 1',
    text: 'Description.\nSay something cool',
    image: require('./assets/1.jpg'),
    imageStyle: styles.image,
    backgroundColor: '#59b2ab',
  },
  {
    key: 'somethun-dos',
    title: 'Title 2',
    text: 'Other cool stuff',
    image: require('./assets/2.jpg'),
    imageStyle: styles.image,
    backgroundColor: '#febe29',
  },
  {
    key: 'somethun1',
    title: 'Rocket guy',
    text: 'I\'m already out of descriptions\n\nLorem ipsum bla bla bla',
    image: require('./assets/3.jpg'),
    imageStyle: styles.image,
    backgroundColor: '#22bcb5',
  }
];

export default class App extends React.Component {
  this.state = {
    showRealApp: false
  }
  _onDone = () => {
    // User finished the introduction. Show real app through
    // navigation or simply by controlling state
    this.setState({ showRealApp: true });
  }
  render() {
    if (this.state.showRealApp) {
      return <App />;
    } else {
      return <AppIntro slides={slides} onDone={this._onDone}/>;
    }
  }
}

Configuring buttons

import React from 'react';
import { Ionicons } from '@expo/vector-icons';
import { StyleSheet, View } from 'react-native';
import AppIntro from 'rn-app-intro-screen';

const styles = StyleSheet.create({
  buttonCircle: {
    width: 40,
    height: 40,
    backgroundColor: 'rgba(0, 0, 0, .2)',
    borderRadius: 20,
    justifyContent: 'center',
    alignItems: 'center',
  },
  image: {
    width: 320,
    height: 320,
  }
});

// slides = [...]

export default class App extends React.Component {
  _renderNextButton = () => {
    return (
      <View style={styles.buttonCircle}>
        <Ionicons
          name="md-arrow-round-forward"
          color="rgba(255, 255, 255, .9)"
          size={24}
          style={{ backgroundColor: 'transparent' }}
        />
      </View>
    );
  }
  _renderDoneButton = () => {
    return (
      <View style={styles.buttonCircle}>
        <Ionicons
          name="md-checkmark"
          color="rgba(255, 255, 255, .9)"
          size={24}
          style={{ backgroundColor: 'transparent' }}
        />
      </View>
    );
  }
  render() {
    return (
      <AppIntro
        slides={slides}
        renderDoneButton={this._renderDoneButton}
        renderNextButton={this._renderNextButton}
      />
    );
  }
}

Custom slide layout

import React from 'react';
import { Ionicons } from '@expo/vector-icons';
import { StyleSheet, View, Text, Image } from 'react-native';
import { LinearGradient } from 'expo';
import AppIntro from 'rn-app-intro-screen';

const styles = StyleSheet.create({
  mainContent: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'space-around',
  },
  image: {
    width: 320,
    height: 320,
  },
  text: {
    color: 'rgba(255, 255, 255, 0.8)',
    backgroundColor: 'transparent',
    textAlign: 'center',
    paddingHorizontal: 16,
  },
  title: {
    fontSize: 22,
    color: 'white',
    backgroundColor: 'transparent',
    textAlign: 'center',
    marginBottom: 16,
  }
});

const slides = [
  {
    key: 'somethun',
    title: 'Quick setup, good defaults',
    text: 'rn-app-intro-screen is easy to setup with a small footprint and no dependencies. And it comes with good default layouts!',
    icon: 'ios-images-outline',
    colors: ['#63E2FF', '#B066FE'],
  },
  {
    key: 'somethun1',
    title: 'Super customizable',
    text: 'The component is also super customizable, so you can adapt it to cover your needs and wants.',
    icon: 'ios-options-outline',
    colors: ['#A3A1FF', '#3A3897'],
  },
  {
    key: 'somethun2',
    title: 'No need to buy me beer',
    text: 'Usage is all free',
    icon: 'ios-beer-outline',
    colors: ['#29ABE2', '#4F00BC'],
  },
];

export default class App extends React.Component {
  _renderItem = props => (
    <LinearGradient
      style={[styles.mainContent, {
        paddingTop: props.topSpacer,
        paddingBottom: props.bottomSpacer,
        width: props.width,
        height: props.height,
      }]}
      colors={props.colors}
      start={{x: 0, y: .1}} end={{x: .1, y: 1}}
    >
      <Ionicons style={{ backgroundColor: 'transparent' }} name={props.icon} size={200} color="white" />
      <View>
        <Text style={styles.title}>{props.title}</Text>
        <Text style={styles.text}>{props.text}</Text>
      </View>
    </LinearGradient>
  );

  render() {
    return (
      <AppIntro
        slides={slides}
        renderItem={this._renderItem}
        bottomButton
      />
    );
  }
}

Here a custom renderItem is supplied and the bottomButton-props has been set to true. Notice how the setup of slides has been configured to support icons and gradient backgrounds.

Props and options

The component extends FlatList so all FlatList-props are valid.

renderNextButton	function	renders a Text-component	Use to supply your own next button
renderPrevButton	function	renders a Text-component	Use to supply your own prev button
renderDoneButton	function	renders a Text-component	Use to supply your own done button
renderSkipButton	function	renders a Text-component	Use to supply your own skip button
renderItem	function	renders DefaultSlide	Function returning a slide. The function is passed the slide object as wells as { topSpacer: Number, bottomSpacer: Number }. These show the "safe-space" where other UI is not interfering - take a look at DefaultSlide.js too see how they are set up.

Configure behavior

Name	Type	Default	Description
slides	object	No default, required	An array of slide-objects
showSkipButton	boolean	false	Enable to show a skip button to the left of pagination dots. When bottomButton == true the skip button is a small text under the full-width next button
showPrevButton	boolean	false	Enable to show a previous button. If showSkipButton is true, the skip button will be displayed on the first page and prev button on subsequent one
hideNextButton	boolean	false	Enable to hide the next button
hideDoneButton	boolean	false	Enable to hide the done button
onSlideChange	function	void	Called when user goes changes slide (by swiping or pressing next/prev). Function called with arguments index: number, lastIndex: number
onDone	function	void	Called when user ends the introduction by pressing the done button
onSkip	function	void	Called when user presses the skip button

slide object

Each slide object should contain at least a unique key. If you use the default layouts your object should furthermore contain:

Name	Type	Note
title	string	The title
titleStyle	Style-prop	Styling for the title (e.g color, fontSize)
text	string	Main text of slide
textStyle	Style-prop	Styling for the text (e.g color, fontSize)
image	Image-source prop	Slide image
imageStyle	Style-prop	Styling for the image (e.g. size)
backgroundColor	string	Slide background color

If you use a custom renderItem-method you can design your slide objects as you see fit.
