    });

    when(mockClassObject.inboundReferences).thenReturn(inboundRefsNotifier);

+    // Intebtionally unwaited.
+    // ignore: discarded_futures


is there a way we can turn this lint off for the test/ directory?

I did not find how to exclude just one lint for a directory.

I think code reader will benefit from seeing that a future is dropped.

I would like the fixes to go to separate PRs. They may affect functionality and tests. And I do not want this massive PR to be held by this and thus become victim of error-prone merges.

Created bug: #4668
