Going with the flow - Kotlin Vocabulary

Suspend functions in Coroutines are meant for one-shot calls that could return a result. But, how can you create a stream of data to return multiple results over time? In this video of Kotlin Vocabulary, Manuel will give us the benefits of Kotlin Flow, and much more!

Nice, but audio quality should be better

[abu-bakrpereirakebe]

Rewrote the entire application to use flow and greatly improved performance. Great video.

[ArjunVerma-lqcf]

Great video, I didn't understand the firebase part in the doc but in this video, I know now what it is, and also it is a good idea to explain the same code in video and doc, Keep up the good work!

[hessamemami]

Great talk, It would be awesome if you also make a video about Stateflow

[juanf.mateosredondo]

Thanks, Manuel. Now I can go with the flow as Queen of the Stone Age does.

Since flow are executed in the same context we called collect from, the video example fetches the latest news on the main thread. In-order to transfer fetch the latest news to the worker/IO thread we can make use of flowOn() intermediate operator.
For details please check out the Android docs on Kotlin Flow (section - Executing in different coroutine context)

In 4:36 should be while(isActive) to stop emitting when the coroutine scope is cancelled?

[annavonvornewievonhintengleich]

Thx Google. Whats the defference to LiveData?

[jaya-surya-t]

CallbackFlow is still under "ExperimentalCoroutinesApi" right ?, any ideas on when it would be promoted to completely stable ?

[erictsang]

Great explanation with lots of relatable examples!!! Replacing LiveData with Flow in my side project haha

[ssverma]

Nice, Now waiting for the state and shared flow video ...

[YoutCodeProgrammingTutorials]

can I ask u what tool u are using to make this great presentations !?

[maartentrompper]

Flow is pretty cool, but I find it quite difficult to manage coroutine contexts when making Flow into a StateFlow -- and unsure what the heck is going on. It would be nice to get some easy-to-understand resources about this.

[pushpitakarmakar]

Doesn't this use case of making requests in fixed intervals fall under a WorkManager?

[donellmtabvuri]

This is a very good explanation, the LiveData and Flow codelab was challenging for me and this just cleared up all the frustration I was having using Flow, gracias!!

[soumen_pradhan]

Why does it feel like they removed callback hell using suspend functions and then added it right back using callbackFlow,

[samuelho]

Since flows can be active over a long period of time, does that mean that they should be called from the IO dispatcher? ie. In the first example, there is a while loop in the flow. Would that result in useless work being done / a coroutine being active when it's not needed for most of the time?

[dreamerslab]

So flow is a stream of data in which we can emit new data. Cool

[ismailnurudeen]

Amazing, I'm replacing RxJava in our current project with Flows.

[jakubwegrzyn]

How about integration with jetpack compose? Is there any?
