kotlinlang

is there any flow operator that filters unique values ?

There is `distinctUntilChanged`. A `distinct`/`unique` filter would grow because it would have to cache all values...maybe `toSet` is an alternative for you? Otherwise a `distinct` can be implemented via `filter`

yes, that was my approach, custom operator with a set. thanks

the emissions are few, so no problem in my case
