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({

    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' }}

      />
    );
  }
}

Configuring custom buttons for every single slide

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({
  image: {
    width: 320,
    height: 320,
  }
});

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'],
    buttons: [
      {
        platform: 'ios',
        title: 'Slide Button 1',
        onPress: () => console.log('somethun custom button 1'),
        containerStyle: {{ height: 44 }},
        buttonTextStyle: {{ color: '#000' }}
      },
      {
        platform: 'android',
        title: 'Slide Button 2',
        onPress: () => console.log('somethun custom button 2'),
        containerStyle: {{ height: 44 }},
        buttonTextStyle: {{ color: '#000' }}
      },
      {

      },
    ],
  },
  {
    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'],
    buttons: [
      {
        title: 'Slide Button 3',
        onPress: () => console.log('somethun2 custom button 1'),
        containerStyle: {{ height: 44 }},
        buttonTextStyle: {{ color: '#000' }}
      },
      {
        title: 'Slide Button 4',
        onPress: () => console.log('somethun2 custom button 2'),
        containerStyle: {{ height: 44 }},
        buttonTextStyle: {{ color: '#000' }}
      },
    ],
  },
]

export default class App extends React.Component {
  render() {
    return (
      <AppIntroSlider
        slides={slides}
        useSlideButtons
        disableBottomButtonMargin
      />
    );
  }
}

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,
        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.

Each slide object should contain at least a unique key. If you use the default layouts your object should furthermore contain:

slide buttons array of object

If you use a custom renderItem-method you can design your slide objects as you see fit.
