Dart extension always spend a lot of memory

See original GitHub issue

I have a problem with Dart extension on VSCode. It always spends a lot of memory, until I force quit it. Here is some information for debugs:

  • OS: macOS High Sierra v10.13.6
  • VS Code: version 1.18.2
  • Dart and Flutter extension version: 2.20.0

Provide some images and log from VS Code screen shot 2018-11-04 at 16 24 06 And it still increases until making my laptop lagged.

@larssn it would be better to raise a new issue since it’s probably not related to the issue above (unless you’re on a very old version of Dart).

When the issue gets bad, please could you:

  • Run code --status from the terminal, and include its output
  • Run the *Dart: Capture Logs command, press a few keys to capture the poor performance, then click Stop Logging and provide the log (note: be sure to review it for sensitive info, or email it to logs@dartcode.org if you don’t want to attach publicly)

Thanks!

The dart processes should not persist after closing VS Code, though the java ones could because both Gradle and ADB start daemons that will stay around for a while (they’re reused by multiple instances of VS Code or across sessions for performance).

It’s normal to have multiple Dart processes when editing a single project too, because there are multiple Dart applications in use (for example the analysis server, and the flutter device daemon, and if you’re in a debug session, the flutter run daemon).

If you’re seeing more than 3 Dart processes (or more than 2 when not in a debug session) or if they’re persisting after you close VS Code, then that sounds like it could be a bug - if so, please open a new issue and include the a screenshot of the Details page of Task Manager with the Command Line column visible:

commandline

Thanks!
