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 AppIntroSlider from 'react-native-app-intro-slider';
 
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: 'React-native-app-intro-slider 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,
      }]}
      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 (
      <AppIntroSlider
        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

Configure looks

Name	Type	Default	Description
skipLabel	string	Skip	Custom label for Skip button
doneLabel	string	Done	Custom label for Done button
nextLabel	string	Next	Custom label for Next button
bottomButton	boolean	false	Enable to show a full-width button under pagination
dotColor	string	'rgba(0, 0, 0, .2)'	Color of inactive pagination dots
activeDotColor	string	'rgba(255, 255, 255, .9)'	Color of active pagination dot
renderNextButton	function	renders a Text-component	Use to supply your own next button
renderDoneButton	function	renders a Text-component	Use to supply your own done 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
onSlideChange	function	void	Called when user goes to next slide. 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
text	string	Main text of slide
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.
