Custom slide layout

Custom layout example gif

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-spaceo';
 
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,
  },

    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-spaceo 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 (
      <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

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

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

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

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.
