Ability to verify a prop is a React.Fragment

[slorber]

@ljharb suggested here to open a new issue to verify react fragment proptypes: #211 (comment)

Just to give more context, for react-intl FormattedMessage component, I'd like to submit a PR to add support for fragments.

Currently the lib has tagName: PropTypes.oneOfType([PropTypes.string, PropTypes.element]),

I want to submit a PR to update to something like tagName: PropTypes.oneOfType([PropTypes.string, PropTypes.element, React.Fragment]),

The lib is able to support fragments at runtime. I'm already using tagName=Fragment. I just want a solution to remove the propTypes warning I have when using Fragments.

I've noticed it works with elementType but I guess my PR wouldn't be accepted by react-intl team as it's a bit too "wide" and less specific

I'm currently using PropTypes.symbol as a work around to suppress the error. I'm not sure if that is specific enough to avoid any possible edge cases though.

@slorber PropTypes.oneOfType([PropTypes.string, PropTypes.element, PropTypes.oneOf([React.Fragment])) should do it, no?

[slorber]

Hmmm maybe, didn't try that one ;)

Using TS now so not really using proptypes anymore

[ljharb]

TS isn’t a replacement for PropTypes; it can check number but not integer; it doesn’t have negated types yet; it can’t do ranges, or many other things. I’d strongly suggest using both.

However. I’ll close this, if you no longer have the feature request.
