"Run" button in vscode not working when using latest dart (dev) sdk. #52222

mmcdon20 · 2023-04-29T21:09:45Z

Dart SDK version: 3.1.0-56.0.dev (dev) (Fri Apr 28 13:05:51 2023 -0700) on "windows_x64"

I'm not sure if this is the right place to report an issue relating to vscode, but when you click on "Run" (where it says "Run | Debug" above main), vscode just stalls and the program never actually runs.

The button works correctly with a dart 2.19.x sdk, and also the "Debug" button works even in the latest dev SDK, and typing dart bin/hello.dart from the console works as well.

The text was updated successfully, but these errors were encountered:

@DanTup coud you take a look?

mraleph · 2023-05-01T13:09:49Z

This might need to be moved to VSCode repo unless this is actually an SDK problem.

DanTup · 2023-05-01T15:37:36Z

@mmcdon20 I don't seem to be able to reproduce this (using Windows and the same dev SDK) with either release or pre-release versions of the Dart extension.

Could you confirm:

whether your project has a pubspec.yaml (if so, please post a copy)
whether there are any errors in the Console tab if you click Help -> Toggle Developer Tools in VS Code

Could you you also capture a log:

Run the Dart: Capture Debugging Logs command
Click the Run button to trigger the issue
Wait for at least 10 seconds
Click Cancel on the logging notification to stop logging and open the log
Remove anything sensitive from the log
Attach the log here (or in a gist)

I'm not sure whether it's a Dart-Code issue or not. It's possible it could be a Debug Adapter issue (we're migrating to new debug adapters that live here in pkg:dds). With a log file it might be clearer where this issue belongs.

Thanks!

@mmcdon20 thanks - unfortunately not much helpful there. It seems like nothing happens after VS Code sends the request to launch.

Can you confirm that when you're running dart bin\hello.dart you're using the same version of Dart being picked up here (from C:\\src\\flutter\\bin\\cache\\dart-sdk\\bin\\dart.exe)? Eg. does everything work if you do:

cd C:\Users\mmcdo\Desktop\experiment
C:\src\flutter\bin\cache\dart-sdk\bin\dart.exe --enable-asserts bin\hello.dart

Also - I don't suppose you can easily switch back to the 2.19 SDK where this worked and capture the same log as above? It'd be interesting to know if the version where it worked was using the new SDK DAPs or whether you were on the legacy DAPs (this might help understand if it's a regression in the new DAPs, or there's something that has always failed in your environment here).

mmcdon20 · 2023-05-01T16:43:55Z

It works fine from the command line.

I don't suppose you can easily switch back to the 2.19 SDK where this worked and capture the same log as above? ...

Not a problem, just have to switch to flutter stable channel, and make the following change in pubspec.yaml.

...
environment:
  sdk: ^2.19.6
...

Dart SDK version: 2.19.6 (stable) (Tue Mar 28 13:41:04 2023 +0000) on "windows_x64"

DanTup · 2023-05-01T17:36:51Z

@mmcdon20 thanks! That log confirms you were running the new debug adapters when it worked, so this seems like a recent regression. It turns out I can reproduce this - I had mistakenly just grabbed the latest Dart SDK dev version from the dart website thinking that's what you'd used from the version, but you were on a newer SDK build rolled into Flutter's master channel.

I'll see what I can find. In the meantime, I think the beta channel is unaffected if it's convenient for you to use that until this is fixed.

DanTup · 2023-05-02T11:11:37Z

I have a fix open at https://dart-review.googlesource.com/c/sdk/+/300601. It was a recent regression (a subtle change that affected the order of debug adapter events/responses), and doesn't affect the beta branches of either Dart or Flutter.

Once the bot closes this issue it'll be fixed in the bleeding-edge Dart builds, but it may take a little longer to get to Flutter (it needs to roll into flutter/engine and then flutter/flutter).
