[react-native] Does React Native styles support gradients?

I see that someone made this for it: https://github.com/brentvatne/react-native-linear-gradient

But is there support for it in RN itself? Something like

style = StyleSheet.create({
    backgroundGradient: "vertical",
    backgroundGradientTop: "#333333",
    backgroundGradientBottom: "#666666"
});

U can try this JS code.. https://snack.expo.io/r1v0LwZFb

import React, { Component } from 'react';
import { View } from 'react-native';

export default class App extends Component {
  render() {
    const gradientHeight=500;
    const gradientBackground  = 'purple';
        const data = Array.from({ length: gradientHeight });
        return (
            <View style={{flex:1}}>
                {data.map((_, i) => (
                    <View
                        key={i}
                        style={{
                            position: 'absolute',
                            backgroundColor: gradientBackground,
                            height: 1,
                            bottom: (gradientHeight - i),
                            right: 0,
                            left: 0,
                            zIndex: 2,
                            opacity: (1 / gradientHeight) * (i + 1)
                        }}
                    />
                ))}
            </View>
        );
  }
}

Just export your gradient as SVG and use it using react-native-svg and when after you import your component set width and height and preserveAspectRatio="xMinYMin slice"to scale an SVG gradient at your needs.

Here is a good choice for gradients for both platforms iOS and Android:

https://github.com/react-native-community/react-native-linear-gradient

There are others approaches like expo, however react-native-linear-gradient have worked better for me.

<LinearGradient colors={['#4c669f', '#3b5998', '#192f6a']} style={styles.linearGradient}>
  <Text style={styles.buttonText}>
    Sign in with Facebook
  </Text>
</LinearGradient>

// Later on in your styles..
var styles = StyleSheet.create({
  linearGradient: {
    flex: 1,
    paddingLeft: 15,
    paddingRight: 15,
    borderRadius: 5
  },
  buttonText: {
    fontSize: 18,
    fontFamily: 'Gill Sans',
    textAlign: 'center',
    margin: 10,
    color: '#ffffff',
    backgroundColor: 'transparent',
  },
});

Here is a production ready pure JavaScript solution:

<View styles={{backgroundColor: `the main color you want`}}>
    <Image source={`A white to transparent gradient png`}>
</View>

Here is the source code of a npm package using this solution: https://github.com/flyskywhy/react-native-smooth-slider/blob/0f18a8bf02e2d436503b9a8ba241440247ef1c44/src/Slider.js#L329

Here is the gradient palette screenshot of saturation and brightness using this npm package: https://github.com/flyskywhy/react-native-slider-color-picker

Looking for a similar solution I just came across this brand new tutorial, which lets you bridge a Swift gradient background (https://github.com/soffes/GradientView) library while walking through every step to get a working React component.

It is a step-by-step tutorial, allowing you to build your own component by bridging the swift and objective-c component into a usable React Native component, which overrides the standard View component and allows you to define a gradient like the following:

 <LinearGradient 
   style={styles.gradient} 
   locations={[0, 1.0]} 
   colors={['#5ED2A0', '#339CB1']}
 />

You can find the tutorial here: http://browniefed.com/blog/2015/11/28/react-native-how-to-bridge-a-swift-view/

React Native hasn't provided the gradient color yet. But still, you can do it with a nmp package called react-native-linear-gradient or you can click here for more info

1. npm install react-native-linear-gradient --save
2. use import LinearGradient from 'react-native-linear-gradient'; in your application file

3.         <LinearGradient colors={['#4c669f', '#3b5998', '#192f6a']}>
             <Text>
               Your Text Here
             </Text>
           </LinearGradient> 

First, run npm install expo-linear-gradient --save

You don't need to use an animated tag, but this is what I was using in my code.

inside colors={[ put your gradient colors ]}

then you can use something like this:

 import { LinearGradient } from "expo-linear-gradient";
 import { Animated } from "react-native";

 <AnimatedLinearGradient
    colors={["rgba(255,255,255, 0)", "rgba(255,255,255, 1)"]}
    style={{ your styles go here }}/>

const AnimatedLinearGradient = Animated.createAnimatedComponent(LinearGradient);
