Possible related to https://github.com/dart-lang/sdk/issues/37233.

keertip commented 4 years ago

@stereotype441, could you take a look at this and see if there needs to be changes made to the analyzer. Seeing quite a few reports with this exception in bleeding edge.

srawlins commented 4 years ago

Reported as recently as Dart 2.6.1.

MichaelRFairhurst commented 4 years ago

This was fixed in https://github.com/dart-lang/watcher/pull/75 plus https://dart-review.googlesource.com/c/sdk/+/125765

I am closing, but if we see this occur again with a newer SDK we can reopen.

a-siva commented 4 years ago

@MichaelRFairhurst apparently this issue was seen again with Dart 2.7.0 so I am reopening this issue for investigation.

MichaelRFairhurst commented 4 years ago

Closing, none of those 2.7 versions include the fix.

a-siva commented 4 years ago

@MichaelRFairhurst can you indicate which version of the Dart SDK has the fix, if none of the 2.7 versions has a fix maybe we need to cherry pick this fix and make a release.

The same issue occurs in Dart SDK 2.17.3.

@RB-93 - can you file a new issue? What you're seeing is almost certainly a different problem - this was closed several years ago. Thanks!
