Does <SvgUri /> component support cache?

See original GitHub issue

Does <SvgUri /> component support cache like react native’s <Image /> component?

For example I’m using cache for my remote png files like

     uri: "",
     cache: 'force-cache',

I also needed caching and solved it like this:

// CachedSVGUri.js
import React, {Component} from 'react';
import {SvgFromXml} from 'react-native-svg';
import SVGCacheService from '../services/storage/SVGCacheService';

export async function fetchCached(uri) {
    const cached = await SVGCacheService.getSvg(uri);
    if (cached) {
        return cached;
    } else {
        const response = await fetch(uri);
        const svg = await response.text();
        SVGCacheService.setSvg(uri, svg);
        return svg;

export default class CachedSvgUri extends Component {
    state = {xml: null};
    componentDidMount() {
    componentDidUpdate(prevProps) {
        const {uri} = this.props;
        if (uri !== prevProps.uri) {
    async fetch(uri) {
        try {
            this.setState({xml: uri ? await fetchCached(uri) : null});
        } catch (e) {
    render() {
        const {
            state: {xml},
        } = this;
        return <SvgFromXml xml={xml} override={props} />;
// SVGCacheService.js
import AsyncStorage from '@react-native-community/async-storage';

const ASYNC_STORAGE_KEY = 'svg-cache';

let data = null;

const loadData = async () => {
    const defaultData = {
        svgs: {},

    const result = await AsyncStorage.getItem(ASYNC_STORAGE_KEY);
    data = result ? await JSON.parse(result) : defaultData;
    data = {...defaultData,};

export default class SVGCacheService {
    static async setSvg(uri, svg) {
        const oldData = data || {};

        const newData = {
            svgs: {
                [uri]: svg,

        data = newData;

        await AsyncStorage.setItem(ASYNC_STORAGE_KEY, JSON.stringify(newData));

    static async getSvg(uri) {
        if (data === null) await loadData();
        return data.svgs[uri];
