npm install react-native-elevation
`

Usage

`js
import { Component } from 'react'
import { View, Text, Animated, StyleSheet } from 'react-native'

import Elevations from 'react-native-elevation'

const styles = StyleSheet.create({
some: {
margin:8,
...Elevations[4]

API

Elevations

An array of elevations from 0 to 24 that use platform specific styles

Methods

`Elevations.interpolate(animatedValue, {inputRange:Array,outputRange:Array})`

Does interpolated animation on the animatedValue. Remember that, outputRange values must be integers between 0 to 24.

Notes

On iOS, target view should have overflow:'visible'` for the shadow to show up.

React Native Web might show some warning on devTools console while animating. This is due to use of CSS variables and React Native Web handling it poorly. This should be ignored.
