I'll defer to @jwren or @helin24 who have more current context but as scary as this introspection is, it seems reasonable (if unfortunate). The guards seem to mitigate risk too.

Sorry for the delay. The Flutter IJ plugin doesn't have tests for changes like this which is unfortunately. @AlexV525, I have not had a chance to test / validate this change myself, but would be very happy to have it land. If you have cycles, do add a few notes point out the history here in the code, and rebase to recent changes on master. Regardless though of your time, this is a good change and I'll make sure it lands for either M85.1 or M85.2 if it works as you describe.

I've added a few comments that indicate what the code is trying to do and why, also with src links to the InteliiJ Platform SDK.

The branch is also updated.
