Alphabet Slider

An alphabetic slider component that will move the scroll position of an alphabetically-ordered FlatList to the poisition of the letter pressed on the slider.

Installation

or

yarn add alphabet-slider-react-native

Usage

This package is meant to be used alongside a FlatList. The AlphabetSlider component requires 3 props to work: flatListRef, data, and path. The flatListRef is a ref passed to the FlatList component, data is the data passed to the FlatList component, and path is the path into the title of the data item.

In use it would look something like this:

import React, { useRef } from 'react';
import {View, FlatList} from 'react-native';
import AlphabetSlider from 'react-native-alphabet-slider';

const App = () => {
    const flatListRef = useRef<FlatList>(null);

    const DATA = [
        {
            id: 'bd7acbea-c1b1-46c2-aed5-3ad53abb28ba',
            title: 'First Item',
        },
        {
            id: '3ac68afc-c605-48d3-a4f8-fbd91aa97f63',
            title: 'Second Item',
        },
        {
            id: '58694a0f-3da1-471f-bd96-145571e29d72',
            title: 'Third Item',
        },
    ];

    type ItemProps = {title: string};

    const Item = ({title}: ItemProps) => (
        <View style={styles.item}>
            <Text style={styles.title}>{title}</Text>
        </View>
    );

    return (
        <View>
        <FlatList
            data={DATA}
            renderItem={({item}) => <Item title={item.title} />}
            keyExtractor={item => item.id}
            ref={flatListRef}
        />
        <FlatList flatListRef={flatListRef} data={DATA} path="title" />
        </View>
    );
};
