Flow API in Kotlin is a better way to handle the stream of data asynchronously that executes sequentially. ?, ???) There are many applications and uses-cases where combine can be applied, waiting on two observable changes e.g we want to show list of articles to the users and also want to mark unread articles with some notification on article if user has not read , so in one flow we are getting list of articles allArticlesFlow and the other flow we are getting list of user read articles userReadArticlesFlow so we want to see latest copies of both to prepare final data for views. The critical difference from the combine is that the resulting Flow completes as soon as one of the flows completes and cancel is called on the remaining Flow. flatMapConcat for waiting for each "sub"-Flow to complete before collecting (i.e. flow.collect now will start extracting the value from the flow on the Main thread as Dispatchers. rev2023.1.18.43176.
