react-native-app-intro-slider

An easy-to-use yet very configurable app introduction slider/swiper based on FlatList that supports RTL.

yarn add react-native-app-intro-slider

Usage

Simple examples

| Basic | 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:

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

const slides = [
  {
    key: 'one',
    title: 'Title 1',
    text: 'Description.\nSay something cool',
    image: require('./assets/1.jpg'),
    backgroundColor: '#59b2ab',
  },
  {
    key: 'two',
    title: 'Title 2',
    text: 'Other cool stuff',
    image: require('./assets/2.jpg'),
    backgroundColor: '#febe29',
  },
  {
    key: 'three',
    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} data={slides} onDone={this._onDone}/>;
    }
  }
}

Configuring buttons

import React from "react";
import Icon from "react-native-vector-icons/Ionicons";
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"
  }
  //[...]
});

// slides = [...]

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

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.
