| firstItem | number | default is 0 , index of image to display when slider box loads |

1- add below import in your code :

import { SliderBox } from "react-native-image-slider-box";

2- Define your image array source, for below examples i create array in state.

export default class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      images: [
        "https://source.unsplash.com/1024x768/?nature",
        "https://source.unsplash.com/1024x768/?water",
        "https://source.unsplash.com/1024x768/?girl",
        "https://source.unsplash.com/1024x768/?tree", // Network image
        require('./assets/images/girl.jpg'),          // Local image
      ]
    };
  }
  // other component code ...
}

3- Use SliderBox such as these below examples :

Example 1 : SliderBox without and handler or customization

<SliderBox images={this.state.images} />

Example 2 : SliderBox with image press handler and currentImageEmitter

<SliderBox
  images={this.state.images}
  onCurrentImagePressed={index => console.warn(`image ${index} pressed`)}
  currentImageEmitter={index => console.warn(`current pos is: ${index}`)}
/>

Example 3 : SliderBox with image press handler and change slider height (default is 200)

<SliderBox
  images={this.state.images}
  sliderBoxHeight={400}
  onCurrentImagePressed={index => console.warn(`image ${index} pressed`)}
/>

Example 4 : SliderBox with custom width from parent. use onLayout function by calling it from root View of component.

onLayout = e => {
  this.setState({
    width: e.nativeEvent.layout.width
  });
};

render() {
    return (
        <View style={styles.container} onLayout={this.onLayout}>
            <SliderBox
                images={this.state.images}
                sliderBoxHeight={200}
                onCurrentImagePressed={index =>
                    console.warn(`image ${index} pressed`)
                }
                parentWidth={this.state.width}
            />
        </View>
    );
  }

Example 5 : SliderBox with custom dots color

<SliderBox
  images={this.state.images}
  sliderBoxHeight={200}
  onCurrentImagePressed={index => console.warn(`image ${index} pressed`)}
  dotColor="#FFEE58"
  inactiveDotColor="#90A4AE"
/>

Example 6 : SliderBox with custom dot style

<SliderBox
  images={this.state.images}
  sliderBoxHeight={200}
  onCurrentImagePressed={index => console.warn(`image ${index} pressed`)}
  dotColor="#FFEE58"
  inactiveDotColor="#90A4AE"
  dotStyle={{
    width: 15,
    height: 15,
    borderRadius: 15,
    marginHorizontal: 10,
    padding: 0,
    margin: 0
  }}
/>

Example 7 : SliderBox with change paging box padding (Vertical height from bottom of SliderBox) + add autoplay and circleLoop attribute for jump to the first image after swipe the last one.

<SliderBox
  images={this.state.images}
  sliderBoxHeight={200}
  onCurrentImagePressed={index => console.warn(`image ${index} pressed`)}
  dotColor="#FFEE58"
  inactiveDotColor="#90A4AE"
  paginationBoxVerticalPadding={20}
  autoplay
  circleLoop
/>

---

Example 8 : use Custom Image Component, customize pagination, image modes and dotStyles:

<SliderBox
  ImageComponent={FastImage}
  images={this.state.images}
  sliderBoxHeight={200}
  onCurrentImagePressed={index => console.warn(`image ${index} pressed`)}
  dotColor="#FFEE58"
  inactiveDotColor="#90A4AE"
  paginationBoxVerticalPadding={20}
  autoplay
  circleLoop
  resizeMethod={'resize'}
  resizeMode={'cover'}
  paginationBoxStyle={{
    position: "absolute",
    bottom: 0,
    padding: 0,
    alignItems: "center",
    alignSelf: "center",
    justifyContent: "center",
    paddingVertical: 10
  }}
  dotStyle={{
    width: 10,
    height: 10,
    borderRadius: 5,
    marginHorizontal: 0,
    padding: 0,
    margin: 0,
    backgroundColor: "rgba(128, 128, 128, 0.92)"
  }}
  ImageComponentStyle={{borderRadius: 15, width: '97%', marginTop: 5}}
  imageLoadingColor="#2196F3"
/>

Example 9 : SliderBox with activeOpacity:

<SliderBox
  images={this.state.images}
  sliderBoxHeight={200}
  activeOpacity={0.5}
/>

Full-Component(Screen) Example:

import React, { Component } from "react";
import { StyleSheet, Text, View } from "react-native";

import { SliderBox } from "react-native-image-slider-box";

export default class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      images: [
        "https://source.unsplash.com/1024x768/?nature",

        "https://source.unsplash.com/1024x768/?tree",
        require('./assets/images/girl.jpg'),
      ]
    };
  }

  render() {
    return (
      <View style={styles.container}>
        <SliderBox
          images={this.state.images}
          onCurrentImagePressed={index =>
            console.warn(`image ${index} pressed`)
          }
        />
      </View>
    );
  }
