Looking at the error log coming from iOS, it seems to properly identify that there isn't an internet connection while processing the request:

Finished with error [-1009] Error Domain=NSURLErrorDomain Code=-1009 "The Internet connection appears to be offline."
NSLocalizedDescription=The Internet connection appears to be offline., NSErrorFailingURLStringKey=https://firebasedynamiclinks.googleapis.com/v1/shortLinks?key=AIzaSyA2m62zqnYe2l19bxplVzZn4ehCQ8QLqYY, NSErrorFailingURLKey=https://firebasedynamiclinks.googleapis.com/v1/shortLinks?key=AIzaSyA2m62zqnYe2l19bxplVzZn4ehCQ8QLqYY, _kCFStreamErrorDomainKey=1}

And if we look further down in the log, it seems to be pointing to Flutter's standard code which probably isn't handling the exception and the assertion failure seems to be coming from Flutter itself:

*** Assertion failure in -[FlutterStandardWriter writeValue:], FlutterStandardCodec.mm:334
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Unsupported value for standard codec'

For this, there's an open issue in flutter repo that you can track for further updates: flutter/flutter#128764

This seems to be a framework issue rather than flutterfire plugin. Also, any scenario related to network connection doesn't belong to flutterfire.
Closing from here. If you disagree, write in comments and I'll reopen it.

As the issue you are referred to is from has been inactive since 2018 is there something more that can be looked in to from the firebase_dynamic_links team, or do we just have to accept that the app crashes without a network connection for some time?

It looks like there have been some similar issue fixed for "in_app_purchase" -> flutter/plugins#4138
