Occasional bursts of "Null check operator used on a null value" on the web

### Steps to reproduce

Cannot reproduce that locally, very few users (spotted just 3 at the moment) experience such issue; also don't know how this impacts user experience, nobody complained yet. However when happens, produces bursts of 100-200 errors in a row, totally flooding logs - like if the error happened upon rendering each frame. One thing in common I noticed is that two users out of three are on iOS 16.7.3, device info like:
`Mozilla/5.0 (iPhone; CPU iPhone OS 16_7_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/16.6 Mobile/15E148 Safari/604.1`
Third was MacOS:
` Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/18.2 Safari/605.1.15`.

As you see, all OS versions are very dated, however still are among [supported platforms](https://docs.flutter.dev/reference/supported-platforms).

Most likely, the issue is related to upgrade to Flutter 3.27.3 - hadn't been noticed in earlier versions.

Can't supply reproducible code sample as there are no reference to our code in the log, see below. I understand the description is very blurry, however the issue is absolutely critical - cannot rollout this version to a wider audience, this would flood us with errors. Would appreciate someone looking into this. 

Thanks
