@liamappelbe How come we are leaking a symbol?

[liamappelbe]

I can make this class public I guess. It's a bit annoying though. This is an implementation detail, it's a private class, and the thing that is supposedly leaking it is a constructor of another private class. Idk if the leak check is broken, or if this is actually technically a leak for some reason I don't understand.

_ObjCReference itself is also not exported. And ObjCObjectRef which is public, doesn't leak it's super type according to the generated Dartdoc.

It might very well be that we use a pattern they don't use in their codebase and it's a false positive.
