Folder with unusual characters in name causes "An error occurred while handling initialized notification"

[calebpeffer]

Hi all.

Folder names with unusual characters (an . in my case) can cause the dart language server to crash. This error completely disabled the Dart extension and printed no trace information to the console except:

Thanks to @DanTup, I found the issue by enabling the analyzer log. Here is a copy of that log:

Removing the period from the fdaf. directory name resolved the Error.

@calebpeffer can you confirm which SDK Version you have? I think this may be fixed by 21cbe33 (#47097) which I think should be included in the latest stable versions of the Dart and Flutter SDKs.

I'm going to close this under the assumption that the change linked to above has fixed the issue. If that's not the case, please let us know and we'll re-open the issue.

For anyone else who stumbled upon this issue and this was the ONLY link to show up in google - after deleting and resintalling Xcode, enabling / disabling / uninstalling extensions yada yada I was only able to fix this by downgrading flutter. Could some of those steps in-between helped? Maybe. I couldn't tell you.

I downgraded using flutter downgrade v3.22.0 (which takes you to 3.19.6)

@erindolson if you're seeing an issue like this on the newest SDKs, please file a new issue with a copy of the log/error and the exact folder name you're seeing this with and I'll take a look. Thanks!
