expo-react-native-shadow v1.0.3

expo-react-native-shadow

This is a port of react-native-shadow that is compatible with Expo and replaces the react-native-svg tags in React Native Shadow with Expo's SVG API. That means no ejecting!

The documentation is the same as react-native-shadow's:

HOW TO USE IT

Installation

you must run the command to install the plugin and its dependences in you project

yarn add expo-react-native-shadow

Implementation

1. import { BoxShadow, BorderShadow } from 'expo-react-native-shadow'

2. Create a styles/options object:

const shadowStyle = {
  width: 100,
  height: 100,
  color: "#000",
  border: 2,
  radius: 3,
  opacity: 0.2,
  x: 0,
  y: 3,
  style: { marginVertical: 5 },
}

3. Wrap your component in BoxShadow or BorderShadow, passing in the shadowStyle object:

import React, { Component } from 'react'
import { TouchableHighlight } from 'react-native'
import { BoxShadow } from 'expo-react-native-shadow'

const buttonStyle = {
  position: "relative",
  width: 160,
  height: 170,
  backgroundColor: "#fff",
}

const shadowStyle = {
  width: buttonStyle.width,
  height: buttonStyle.height,
  color: "#000",
  border: 2,
  radius: 3,
  opacity: 0.2,
  x: 0,
  y: 3,
  style: { marginVertical: 5 }
}

export default class VideoCell extends Component {
  render = () => {
    return (
      <BoxShadow setting={shadowStyle}>
        <TouchableHighlight style={buttonStyle} />
      </BoxShadow>
    )
  }
}
