I think that code should not be throwing an exception. It is trying to resolve "package:flutter/src/widgets/widget_inspector.dart" and not finding it. That may be due to the Flutter SDK not being set, or some other configuration issue. Perhaps you changed the location of the Flutter SDK on disk before opening the project? If you're curious you can see if the problem is likely to re-occur. In your Flutter project, at the bottom of the Project tool window, expand External Libraries. There should be a library named Dart Packages. Expand that and look for flutter/src/widgets/widget_inspector.dart.

If everything looks OK and the problem happens anyway, then something very odd is happening.

No SDK location changed, I was able to navigate to the widget_inspector.dart following your instructions and, the error seemed to be erratic as I was not able to reproduce it (mainly opening and closing Intellij several times 😅).

Thanks for the update. This is a puzzle, but I don't know how it can happen, so I'll leave this open for now.
