Animated linear gradient as background animation or other. This version with some fixes of useNativeDriver and adaptation to work in expo.

Example

Install

1. expo install expo-linear-gradient
2. yarn add https://github.com/evertoont/expo-animated-linear-gradient

Use

import React, { Component } from 'react';
import { AppRegistry, Text } from 'react-native';
import AnimatedLinearGradient, { presetColors } from "expo-animated-linear-gradient";

class HelloWorldApp extends Component {
  render() {
    return (
      <AnimatedLinearGradient customColors={presetColors.instagram} speed={4000}/>
    );
  }
}

AppRegistry.registerComponent('HelloWorldApp', () => HelloWorldApp);

Props

1. customColors A colors array. This package has include some preset colors, default is presetColors.instagram:

export presetColors = {
  instagram: [
    'rgb(106, 57, 171)',
    'rgb(151, 52, 160)',
    'rgb(197, 57, 92)',
    'rgb(231, 166, 73)',
    'rgb(181, 70, 92)'
  ],
  firefox: [
    'rgb(236, 190, 55)',
    'rgb(215, 110, 51)',
    'rgb(181, 63, 49)',
    'rgb(192, 71, 45)',
  ],
  sunrise: [
    'rgb(92, 160, 186)',
    'rgb(106, 166, 186)',
    'rgb(142, 191, 186)',
    'rgb(172, 211, 186)',
    'rgb(239, 235, 186)',
    'rgb(212, 222, 206)',

    'rgb(152, 197, 190)',
    'rgb(100, 173, 186)',
  ]
};

2. speed The speed of the animation. default is 4000.

3. points (experimental) Describe the direction of linear gradient with start point and end point see more

Default:

const DEFAULT_POINTS = {
  start: {x: 0, y: 0.4}, 
  end: {x: 1, y: 0.6}
}

Example:

vertical:

<AnimatedLinearGradient points={{start: {x: 0.5, y: 0}, end: {x: 0.5, y: 1}}}/>

You can find out it is static values, no animate here :( . This points is going to be animateable soon :) .
