Basic example

| No configuration | showSkipButton | bottomButton and showSkipButton | | ---------------------------------------------- | -------------------------------------------------------------- | ------------------------------------------------------------------ | | | | |

The component is based on FlatList so usage is very similar. Pass a data-array to AppIntroSlider along with a renderItem-function (or you can use the default basic layout).

import React from 'react';
import { StyleSheet } from 'react-native';
import AppIntroSlider from 'react-native-app-intro-slider';

const slides = [
  {
    key: 'somethun',
    title: 'Title 1',
    text: 'Description.\nSay something cool',
    image: require('./assets/1.jpg'),
    backgroundColor: '#59b2ab',
  },
  {
    key: 'somethun-dos',
    title: 'Title 2',
    text: 'Other cool stuff',
    image: require('./assets/2.jpg'),
    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'),
    backgroundColor: '#22bcb5',
  }
];

export default class App extends React.Component {
  this.state = {
    showRealApp: false
  }
  _renderItem = ({ item }) => {
    return (
      <View style={styles.slide}>
        <Text style={styles.title}>{item.title}</Text>
        <Image source={item.image} />
        <Text style={styles.text}>{item.text}</Text>
      </View>
    );
  }
  _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 <AppIntroSlider renderItem={this._renderItem} slides={slides} onDone={this._onDone}/>;
    }
  }
}

Configuring buttons

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

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 (
      <AppIntroSlider
        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 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 = ({ item, dimensions }) => (
    <LinearGradient
      style={[
        styles.mainContent,
        dimensions,
      ]}
      colors={item.colors}
      start={{ x: 0, y: 0.1 }}
      end={{ x: 0.1, y: 1 }}
    >
      <Ionicons
        style={{ backgroundColor: 'transparent' }}
        name={item.icon}
        size={200}
        color="white"
      />
      <View>
        <Text style={styles.title}>{item.title}</Text>
        <Text style={styles.text}>{item.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.

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

Configure behavior

| Name | Type | Default | Description | | -------------- | ---------- | -------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- | | slides | object | No default, required | An array of objects (they should either contain a unique key-prop or you should pass a keyExtractor-function to the component) | | 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 | | showNextButton | boolean | true | Disable to hide the next button | | showDoneButton | boolean | true | Disable 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 | Scroll the list to the end | Called when user presses the skip button |

Slide object

If you want to use the default slide layout, your slides can contain the following information:

| 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 |

Methods

| Method Name | Arguments | Description | | ----------- | --------- | ------------------------------------ | | goToSlide | number | Change to slide with specified index | | getListRef | none | Returns the Flat List ref |
