@kenzieschmoll Is this a DevTools issue?

kenzieschmoll commented 2 years ago

If this exception came from interacting with the Performance tool window in IntelliJ (pictured), then I don't think so. Does the flutter-intelliJ plugin call the ext.flutter.inspector.getRootWidgetSummaryTree anywhere? If it does not, then this could be being triggered from DevTools. I would have expected the stack trace to contain some devtools information if that was the case, but maybe DevTools stack frames arent surfaced in any error from IntelliJ - I'm not sure.

Thanks @kenzieschmoll ! Yes, that service extension is used by the built-in inspector.
