vscode: Error revealing files in the explorer

Using Insiders 0ac111466ec925fd5ca180ab9893f51531e419b2 2019-04-01T15:39:08.133Z.

I had VS Code open and ran a command that created some files (see output pane), but they never appeared in the explorer. I opened dev tools and had this:

t.log @ /Applications/Visual Studio Code - Insiders.app/Contents/Resources/app/out/vs/workbench/workbench.main.js:235
/Applications/Visual Studio Code - Insiders.app/Contents/Resources/app/out/vs/workbench/workbench.main.js:1408   ERR Data tree node not found: [object Object]: Error: Data tree node not found: [object Object]

So far I can only reproduce by running some code I can’t share (though it does seem reliable), but it essentially there’s a single .dart file in the folder that’s opened in VS Code, and the extension (during activation) detects that file, runs an external command that writes a bunch of files to this folder, then deletes the original file (it’s creating a project from a template).

I’ll see if I can make something hard-coded that triggers the same issue. If there’s anything you want me to try, or if there’s a way I can log the file system events or something that might shed light, let me know.
