React Native Scrub

A React Native number scrubber using React Native Gesture Handler

Install

yarn add react-native-scrub react-native-gesture-handler

cd ios
pod install

How To Use

onUpdate will return each scrub which should be used to update a display value.

onChange will return when the user stops scrubbing. This can be used to update the display, and update the value passed into the component again. If you adjust the value another way the Scrubber will spring to the new value.

min is the minimum value that is allowed

max is the maximum value that is allowed

step is how the scrubber should create the range from the min to the max.

renderTick will be called with the current index, step value, and allow you to control how each tick is rendered. You can use the one provided or write your own.

Demo

import React, { useState } from 'react';
import { SafeAreaView, View, Text } from 'react-native';
import { Slider, Tick, CenterLine } from 'react-native-scrub';

const App = () => {
  const [display, setDisplay] = useState(50);
  const [value, setValue] = useState(50);

  return (
    <SafeAreaView>
      <Text
        style={{
          paddingVertical: 20,
          fontSize: 40,
          fontWeight: 'bold',
          textAlign: 'center',
        }}
      >
        {display}
      </Text>
      <Slider
        min={10}
        max={100}
        step={1}
        value={value}
        onUpdate={v => {
          setDisplay(v);
        }}
        onChange={v => {
          setDisplay(v);
          setValue(v);
        }}
        renderTick={tick => <Tick key={tick.index} {...tick} />}
      >
        <CenterLine
          style={{
            backgroundColor: 'red',
          }}
        />
      </Slider>
    </SafeAreaView>
  );
