I don't know how to consume Flow properly in Compose Desktop, I have searched but only find examples for Android.

I get the data from Kmongo:

class TagDAO {
    companion object {
        private val tagsDB by lazy { Connection().getCollection<Tag>("tags") }
        fun listTags(): Flow<Tag> {
            return tagsDB.find().toFlow()
        }
    }
}

@Composable
fun form() {
  val tagsFlow = TagDAO.listTags() // Flow<Tag>
  val tagsState by tagsFlow.collectAsState(initial = Tag()) // Only return last value
}

First: use remember to remember the flow avoiding to query the db each recomposition by remember { tagDao.listTags() }.collectAsState()}.
And what do you mean with last value? A flow returns values over time. Compose updates your UI over time. So yeah, you always see the last value of the flow. If you want to show a list, you should fetch a list: Flow<List<Tag>>

Sry, I forgotten remember to paste code.

Yes, I want obtain list of values. Kmongo returns List<Tag> or Flow<Tag>, not like ROOM of Android that returns Flow<List<Tag>>.
