`networkName` React warning

[zkenny]

I get the following warning from React using the FacebookShareButton component:

Warning: React does not recognize the networkNameprop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercasenetworknameinstead. If you accidentally passed it from a parent component, remove it from the DOM element.

Here is my code:

                        <FacebookShareButton
                            className="social-button"
                            url={BASE_URL + pngImageUrl}
                        >
                            <FacebookIcon size={30} round />
                        </FacebookShareButton>

I tried upgrading to the newest version. Is there something I can do to get rid of this warning?
