import Elevations from 'react-native-elevation'

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

class App extends Component {
	render() {
		return (
			<View style={[]}>
				<View style={styles.some}>{...}</View>
				<View style={Elevations[2]}>{...}</View>
				<View style={[{height:100},Elevations[4]]}>{...}</View>

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.
