`useRecordContext` may return `undefined` (v4.0.1)

See original GitHub issue

What you were expecting: useRecordContext returns RaRecord, so it can be used without undefined check

What happened instead: Error was shown, because record data was undefined

Steps to reproduce: Use typescript and the useRecordContext hook. The typing doesn’t show the return type can be also undefined

Other information: This PR recently fixed this for version 3.19.12 but it seems like this didn’t make it into a 4.x release. This issue is also addressing the issue.

So after investigation, it appears tsc won’t include the undefined in the dts file if we don’t set the strictNullChecks to true. We definitely should and will but I can’t give you any ETA as we have more urgent tasks to finish.

If you want to help us make tsc happy, you can activate the strict mode locally, fix a few of the errors and make some PRs (without the tsconfig change for now).

Thanks again for reporting this!
