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:

1import React from 'react';
2import { StyleSheet } from 'react-native';
3import AppIntroSlider from 'react-native-app-intro-slider-cardview';
4
5const slides = [
6  {
7    key: 1,
8    title: 'Title 1',
9    text: 'Description.\nSay something cool',
10    image: require('./assets/1.jpg'),
11    backgroundColor: '#59b2ab',
12  },
13  {
14    key: 2,
15    title: 'Title 2',
16    text: 'Other cool stuff',
17    image: require('./assets/2.jpg'),
18    backgroundColor: '#febe29',
19  },
20  {
21    key: 3,
22    title: 'Rocket guy',
23    text: 'I\'m already out of descriptions\n\nLorem ipsum bla bla bla',
24    image: require('./assets/3.jpg'),
25    backgroundColor: '#22bcb5',
26  }
27];
28
29export default class App extends React.Component {
30  this.state = {
31    showRealApp: false
32  }
33  _renderItem = ({ item }) => {
34    return (
35      <View style={styles.slide}>
36        <Text style={styles.title}>{item.title}</Text>
37        <Image source={item.image} />
38        <Text style={styles.text}>{item.text}</Text>
39      </View>
40    );
41  }
42  _onDone = () => {
43    // User finished the introduction. Show real app through
44    // navigation or simply by controlling state
45    this.setState({ showRealApp: true });
46  }
47  render() {
48    if (this.state.showRealApp) {
49      return <App />;
50    } else {
51      return <AppIntroSlider renderItem={this._renderItem} data={slides} onDone={this._onDone}/>;
52    }
53  }
54}

Configuring buttons

1import React from "react";
2import Icon from "react-native-vector-icons/Ionicons";
3import { StyleSheet, View } from "react-native";
4import AppIntroSlider from "react-native-app-intro-slider-cardview";
5
6const styles = StyleSheet.create({
7  buttonCircle: {
8    width: 40,
9    height: 40,
10    backgroundColor: "rgba(0, 0, 0, .2)",
11    borderRadius: 20,
12    justifyContent: "center",
13    alignItems: "center",
14  },
15  //[...]
16});
17
18// slides = [...]
19
20export default class App extends React.Component {
21  _renderItem = ({ item }) => {
22    return (
23      <View style={styles.slide}>
24        <Text style={styles.title}>{item.title}</Text>
25        <Image source={item.image} />
26        <Text style={styles.text}>{item.text}</Text>
27      </View>
28    );
29  };
30  _renderNextButton = () => {
31    return (
32      <View style={styles.buttonCircle}>
33        <Ion
34          name="md-arrow-round-forward"
35          color="rgba(255, 255, 255, .9)"
36          size={24}
37        />
38      </View>
39    );
40  };
41  _renderDoneButton = () => {
42    return (
43      <View style={styles.buttonCircle}>
44        <Ion name="md-checkmark" color="rgba(255, 255, 255, .9)" size={24} />
45      </View>
46    );
47  };
48  render() {
49    return (
50      <AppIntroSlider
51        data={slides}
52        renderDoneButton={this._renderDoneButton}
53        renderNextButton={this._renderNextButton}
54      />
55    );
56  }
57}

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.
