Does below snippet considered as multiple streams?

Also, is it currently possible to do this approach (in snippet)?

Detailed in thread~

StockViewModelMultipleStream_kt.cpp

[miqbaldc]

There’s a usecase in our apps to fetch 3 different APIs inside 1 screen, e.g:

Header 1

1. list item 1
2. …
3. list item n

Header 2

1. list item 1
2. …
3. list item n

Header 3

1. list item 1
2. …
3. list item n
fetching this different list in parallel, also has it’s side effect for each service, e.g: empty state, loading animation, loaded animation

there’s nothing stopping you from doing that. However, please note that collect will suspend until the relevant stream completes.

This means that unless you launch a separate coroutine for each collect call it won’t get past the first collect

[Mikolaj Leszczynski]

worth doing that on a Dispatchers.Default too so as not to overload the orbit event loop

[Mikolaj Leszczynski]

tip: coroutineScope { } can be used in a suspending block for parallel decomposition

I’m not sure if the dispatchers are absolutely necessary, but just to be on the safe side 😉

ah, that’s great, thanks a lot for the code snippet example as well ❤️ K

found official docs from android regarding the parallel decomposition: https://developer.android.com/kotlin/coroutines/coroutines-adv#parallel

thanks for take time to write the above snippet and giving us a hint to where should we look for references, especially the parallel decomposition part~ ❤️
