I’m having the same issue after removing a part of from a Dart file. Every time I trigger auto complete for the class it tries to get it’s import from the old file it was a part of, instead of the actual path.

Request completionItem/resolve failed.
  Message: No such element: MyClass in package:myapp/old_path_to/the_file_it_was_part_of.dart

Removing (I actually renamed) .dartServer fixed it.
