LinearGradient in react-native-svg not working

Question

I am trying to use SVG in my react native project. This is the code for my component:

<Svg xmlns="http://www.w3.org/2000/svg" width="100%" height="507" viewBox="0 0 375 507" style={{position:'absolute', bottom:0}}>

  <Defs>

     <ClipPath id="a">
        <Rect class="a" fill='#fff' stroke='#707070' width="375" height="507" transform="translate(0 160)" d="M0 0h375v507H0z"/>
    </ClipPath>

    <LinearGradient id="b" clipPath='url(#a)' x1="0.5" x2="-0.031" y2="1.477" gradientUnits="objectBoundingBox">
        <Stop offset="0" stopColor="rgb(76,209,149)"  />
        <Stop offset="1" stopColor="rgb(170,221,100)"  />
    </LinearGradient>

  </Defs>

    <G class="b" transform="translate(0 -160)">
        <Circle class="c" cx="334.249" cy="334.249" r="334.249" transform="translate(-146.354 164.646)"  fill='url(#b)' />
    </G>

</Svg>

The Output I'm getting is:

Don't use clip-path on a linear gradient. Use it on the g class="b" or on the circle Also, I'm not acquainted with react native svg but you have a rect element with a d attribute. In SVG this is a path element not a rect – Ahl

Answer 1

I think @enxaneta is right, clip-path seems to not exist on react-native-svg please refer to the documentation, you may find on the docs here react-native-svg #LinearGradient

I think you should have to reference it like this:

        <Rect class="a" fill="url(#yourGradientId)" stroke='#707070' width="375" height="507" transform="translate(0 160)" d="M0 0h375v507H0z"/>

where fill should be reference to your gradient id i.e. fill=url(#b)

I've used <Path> to achieve the results below

Note: I have achieve this by using two shapes on top of each other:

1. A component with background gradient using react-native-linear-gradient
2. And the LinearGradient from react-native-linear-gradient

Please refer to the codes below.

Code of example above

import Svg, { Path, Defs, LinearGradient, Stop } from 'react-native-svg';
import Gradient from 'react-native-linear-gradient'
const { width, height } = Dimensions.get('window')

      <Gradient style={{height: height * .25,}} 
        colors={ ['#FFD080', 'red'] }
        start={{ x: 0, y: 0}}
        end={{ x:1, y: 1}}
        locations={[0.18, 1, 1]}>
          
            
        <Svg
            height={height * .44}
            width={width}
            viewBox="0 0 1440 320"
            style={{ position: 'relative', top: height * .069 }}
          >
          <Defs>
          <LinearGradient id="path" x1="0" y1="0" x2="1" y2="1">
              <Stop offset="0" stopColor="#FFD080" stopOpacity="1" />
              <Stop offset="1" stopColor="red" stopOpacity="1" />
            </LinearGradient>
          </Defs>
            <Path fill="url(#path)"
               d="M0,96L48,133.3C96,171,192,245,288,229.3C384,213,480,107,576,74.7C672,43,768,85,864,133.3C960,181,1056,235,1152,234.7C1248,235,1344,181,1392,154.7L1440,128L1440,0L1392,0C1344,0,1248,0,1152,0C1056,0,960,0,864,0C768,0,672,0,576,0C480,0,384,0,288,0C192,0,96,0,48,0L0,0Z"/>
        </Svg>
        </Gradient>

Answer 2

I found a solution that instead of using the svgs having gradient,I converted the SVG into a Lottie file. that works great and as an extra advantage, we can transform the SVG into a simple animation :)

Works great:

import React from "react";
import { View, Text } from "react-native";
import { Polygon, Svg, LinearGradient, Stop, Defs, G, Use,} from "react-native-svg";

const Triangle = () => {
  return (
    <Svg viewBox="0 0 386 386">
        <Defs>
            <LinearGradient id="grad" x1="0" y1="0" x2="1" y2="0">
                <Stop offset="0" stopColor="#000" stopOpacity="0.2" />
                <Stop offset="1"         stopColor="#71D4EB" stopOpacity="0.1" />
            </LinearGradient>
        <G id="polygon">
            <Polygon
            points={"193,193 0,386 0,0"}
            fill="url(#grad)"
            strokeWidth={0}
            />
        </G>
      </Defs>

        <Use href="#polygon" x="0" y="0" />
        <Use href="#polygon" x="0" y="0" rotation="180" origin="193, 193" />
        <Use href="#polygon" x="0" y="0" rotation="90" origin="193, 193" />
        <Use href="#polygon" x="0" y="0" rotation="270" origin="193, 193" />
    </Svg>
  );
};

export default Triangle;
