Dart-code: Dart DevTools exited with code 66

[advancedtw]

dart tools fails to launch on vscode was working the morning and still works fine with android studio.
vscode 1.40.1
dart ext 3.6

Could you try capturing a log by running the Dart: Capture Logs command, ticking Command Processes and DevTools then reproducing the issue?

Thanks!

i was not aware of capture logs and thanks to that i fixed it. i copied devtools-0.1.11 from an other user and now it's working as expected but still I'm wondering what is the recommended way to repopulate this directory .pub-cache/hosted/pub.dartlang.org/
also is it is it normal that my log shows : Flutter extension: 3.6.0 (not activated)
thanks a bunch

Weird - I'm not sure how that folder would end up without a pubspec.

The easiest way to fix is probably running pub global deactivate devtools then pub global activate devtools (though the second step will be run by the VS Code extension if you try to launch DevTools and it's not activated).

also is it is it normal that my log shows : Flutter extension: 3.6.0 (not activated)

If you've opened a folder that isn't a Flutter app, this is normal. If it is a Flutter app, then it suggests for some reason we might not be detecting it correctly. If that's the case, please file a new issue with a screenshot showing your folder layout (where the Flutter project is in relation to the top folder you opened) and an extension log.

Thanks!

For other readers, I managed to get into this state because I managed to deleted my entire .pub-cache/hosted/pub.dartlang.org/ directory.

The same approach (deactivate/activate) solved the problem.

Can Anyone help me I'm getting this issue Dart Dev Tools exited with code 225

@sagarkhurana00786 can you include a screenshot/description of where you're seeing this? If in VS Code, can you capture a log (see https://github.com/Dart-Code/Dart-Code/issues/2128#issuecomment-558306435)? Thanks!

same issue today. I did just upgrade flutter. This worked: deactivate devtools then pub global activate devtools

[DanTup]

A new version of DevTools was released that doesn't have a build suffix, so I would not expect anyone to still see this.

If you do still see it when launching DevTools from within VS Code, please let me know (or ping me in Discord), I'd like to understand why it's not updating.
