Thanks!
Was the folder you had open when you got this quite large? And what sort of disk is it on (spinning HDD or SSD?).
The message from VS Code is very misleading, it isn't high CPU but rather just blocking the thread (on synchronous file system access). I've tried making this async in the past but it made the whole thing slower (though because it didn't block the thread, it would eliminate this message). In this case it was only for prompting to run
pub getthough, so maybe having it take a little longer in the background wouldn't be a big deal.sephirothtbm commentedon Sep 11, 2019
Hi,
No, the folder was quite small, actually I'm learning flutter so the folder was the very basic tutorial in the site, my disk is an HDD.

Thanks for the info, I'll see if I can make some improvements.
Do you see this message frequently?
