-/// A wrapper for [ManuallyClosedDirectoryWatcher] that encapsulates support for
-/// closing the watcher when it has no subscribers and re-opening it when it's
-/// re-subscribed.
-///
-/// It's simpler to implement watchers without worrying about this behavior.
-/// This class wraps a watcher class which can be written with the simplifying
-/// assumption that it can continue emitting events until an explicit `close`
-/// method is called, at which point it will cease emitting events entirely. The
-/// [ManuallyClosedDirectoryWatcher] interface is used for these watchers.
-///
-/// This would be more cleanly implemented as a function that takes a class and
-/// emits a new class, but Dart doesn't support that sort of thing. Instead it
-/// takes a factory function that produces instances of the inner class.
