updating the pr, but highly disappointed on the lack of communications from the firebase team, especially on cases where the work is provided for you

Hey Sergio, apologies for the slow response. We'll take a look. Thanks for making this PR!

Sorry again for the delay Sergio, there are some discussions around whether userInfo should be nullable or not, and if it is, what happens when you pass nil to any other previously set keys when using setCustomValue.

@sergiocampama we are able to approve this API now. I'm just going to suggest a small addition to the comment and then submit the change.

Could you update the comment

• @param userInfo Additional parameters to send with the record
• to be: @param userInfo Additional keys and values to send with the logged error. These parameters are added to Crashlytics global list of keys and values that live with the session.

@samedson thanks! I've updated the PR with the comments change and made sure to run the style script for the check to pass.
