@matanlurey do you have exact steps to reproduce this? I tried what I think you're doing, but wasn't able to repro (the red squiggle is just missing semicolon).

uri.mp4

Capturing a server log might be useful too.

Other way around, create the zone.dart from the menu.

Ah, thanks - I managed to repro it a few times intermittently, but each time was after I deleted and re-used the same filename. I'm not sure if that's coincidence or not - do you know if this is the same for you (did you delete the file once before it happened)?

(I suspect it's coincidence, but since it's intermittent for me and only happened after that, it'd be good to know if that might be a requirement)

[matanlurey]

It was consistent for me, but I think I could imagine it being intermittent.

Ok, I think I might be seeing the error only when I've been in that state previously before. It might be coincidence, but I can reliably reproduce it by:

• create the file (foo.dart) with an export for bar.dart that produces this error (because the file bar.dart doesn't exist)
• delete the export from foo.dart
• create the file bar.dart
• add the export of bar.dart back into foo.dart (specifically so that the file foo.dart is exactly as it was before when it had the error)

@scheglov @bwilkerson do we cache the diagnostics in any way? Could it be that restoring the file to how it was before is getting the old diagnostics (eg. something isn't being flushed correctly when a file is created?). This sounds a little familiar like we may have discussed this before..!

[DanTup]

#53683 is the issue I was thinking of which was believed to be fixed (maybe @scheglov has ideas).

Thanks! If there is anything I can do to help please LMK
