How to emit a final item after all the items in the Flowable are emitted

I want to emit a final item after all the items in the Flowable are emitted. For now I can achieve this via the following code.

Flowable<String> flowable = getFlowable();
flowable.toList()
        .toFlowable()
        .flatMap(stringList -> {
            stringList.add("final String");
            return Flowable.just(stringList);
        })
        .subscribe(System.out::println);

The problem is, it waits until all the items are obtained before emitting. I want them to be emitted immediately when they are obtained, one at a time, and an extra final String could be emitted right after the last item, how to achieve that?

You can use concatWith

flowable.concatWith(Flowable.just(stringList))
        .subscribe(System.out::println);
