This is done by the Dart plugin. I think the incorrect lines are always drawn below a left paren. (If not, then my guess as to how it is drawn is wrong, but it is still in the Dart plugin.) I suspect the code that does this was not updated after the Dart plugin stopped using its own formatter.
I created https://youtrack.jetbrains.com/issue/WEB-59450/Dart-indent-guides-anomaly
It appears that the lines that are displaying incorrectly are controlled by the IntelliJ setting, not the Flutter plugin setting. (Let me know if I misunderstood.)
I’ll have to check how those lines are drawn. It seems like it should be done by a plugin, but might be Dart.
