Your basic videos are almost always enough to keep me going on my huge project. Thanks a bunch

[@alekseyyakovlev6924]

Thanks for the tutorial, can you make a video with comparing Flow vs StateFlow vs SharedFlow?

[@shubhamnaik1982]

You are the only one on TH-cam Providing In-Depth Knowledge for Android App Development Using Kotlin and it really helped bro 😍🙏

[@pierre.vieira]

Thank you very much for this video. I've always used flow but I didn't really understand how it worked, now it's all clearer!

[@user-jx5or8pk2m]

Really easy to understand.. you woudln't know how much I appreciate you by this tutorial. Thx alot!

[@alexwhb122]

Fantastic explanation! I finally get back pressure! Thank you so much.

Thanks for this quality content.

[@shidqi100]

Nice video man, i really hope you make kotlin flow as a series with depth explanation and example project

[@PhilippLackner]

That's what I do in my Ktor course on pl-coding.com for caching

[@ronn1NNNNN]

when its Kotlin and Android development learning, you are next to God.

[@PhilippLackner]

Thanks a lot man!

"Flows are like LiveData on steroids!" hahhahah nailed it! Loved it

[@RRRazzzaRRR]

thnx, as always top!

you made flow very easy ,, thanks

[@aneessaleh2870]

great video man , keep it up

[@PhilippLackner]

Thanks, will do!

[@xenofonkarydis6406]

So we are waiting for a WebSocket with Flows lesson (and especially how to get informed about the end-points disconnection, or a ping-pong mechanism) from you..!!! :) :) :)

[@abuiman5251]

Thanks!!!

Great 👍

an amazing video , tnx

[@androidmillennium9266]

Thanks a lot

[@be_like__prateek]

Liked your content.

[@leonardosibela]

Flow is like design patterns. It's not so easy to understand how it works. The hard part is to understand when to use them.

[@CriticasDeCriticas]

well not really, just use it as a replacement of live data, pretty straight forward

[@nicolasvantsis6166]

Very nice. Maybe you can use this to your next tutorial. 😉

[@yutaitadori7318]

I'm your fan ♥️

thanks

[@theonlyarjun]

how did you get the rainbow logcat, is that a plugin or you manually configured it?

[@Chintanparmar]

Yes. Rainbow Brackets is the plugin

[@felipepereira3061]

Are u planing a mvi tutorial with retrofit and flow too? =)

[@prasuguna]

Whenever I have any doubts I type philip lanker the concept name.

[@wenlongteo6272]

Hi, your explanation is so good and details, I might consider to subscribe to your course :)
One question is that what plugin you used for your logcat?
And also recently I working with paging3 Android, maybe you can consider to work on a tutorial on that

[@PhilippLackner]

Thanks! That's not a plugin, just press Ctrl+Alt+S to open settings and search for logcat. There you can change the colors

[@babythedude]

thanks! How do you get colorful log like in 6:50 ?

[@dindjarin2628]

'emit' and 'collect' reminds me with Plant vs Zombie, where we have to collect sunlight emitted from sunflowers.

[@PhilippLackner]

hahaha yea

[@Trecoolerok]

Great, thanks. How is flow comparing to rx.java?

[@souptiknath4668]

From where do you learn these new concepts?

[@mehulbisht9708]

if i wish to build a Tic Tac Toe game that requires the user to click a box and make his turn every 30 seconds ( at the max ), then is using firebase cloud firestore better or i need to use a websocket for this stuff ? ( i mean for sending and receiving what the other user clicked in his turn )

[@PhilippLackner]

I'd use websockets, with firebase it's hardly possible to do something based on time

[@micahspecial5927]

Hi Philips, can you explain about gradle build, and which one to use? i always got error there but the code is fine :(

[@abdremo]

thanks fleep

[@Tech-To-Logic]

Philipp, which thread this flow coroutine run? Can I define dispatcher with this flow? How to manage that?

[@PhilippLackner]

flow.flowOn(yourDispatcher)

[@MDDanishAnsariDev]

Which plugin have you used for colorful logs in Logcat?

[@PhilippLackner]

No plugin, just Android Studio settings

[@MDDanishAnsariDev]

@@PhilippLackner Got it. Thanks.

[@yasminedwedar8651]

@@PhilippLackner how

[@jayeshsuthar5590]

Hii nicely explained
I'd like to say one thing though i.e. when you say they both are running in the same Coroutines, it's not true. Flow builder has its own Coroutine and Global scope.launch has its own Coroutine.

[@theonlyarjun]

next stateFlow and sharedFlow please

[@iam-learning6374]

Hi Philipp - Could you please make one video on Android KTX... thanks in Advance.

[@ronn1NNNNN]

do you have course for android development with kotlin (in udemy or so), where we can find content in proper arranged manned , so that learning would be easy and in proper curve ?

[@PhilippLackner]

I have premium courses on my website pl-coding.com, check it out :) Within the next week I'll publish a new course about making a social network android app using Kotlin and Firebase

[@Igalsr]

Reminds me of Flutter Stream Builder

[@pradeepkumarreddykondreddy7048]

This looks similar to RxJava Observable and Observer

[@PhilippLackner]

It is, but based on coroutines

[@rahulkumar-td7pn]

so flow acts as both observable or flowable and observer or subscriber

[@fahrican9708]

What about this drawing game with web sockets you talked about? Will you publish it as a playlist?

[@PhilippLackner]

No but I might publish it to playstore

[@fahrican9708]

@@PhilippLackner okay, a tutorial about Scarlet with use of any web socket would be also interesting

[@Qrzychu92]

So it's basically channels from Go. They are also implemented in C# BTW :P and pretty much every other language

[@gofudgeyourselves9024]

Can you create Kotlin Multiplatform tutorials?

[@vathsan3906]

So you were working on DoodleKong from October 2020 or before... WOW

[@GakisStylianos]

I don't know about the "they are basically LiveData on steroids" part.
It's not exactly the same thing and saying that they are very similar might bring some confusion on the topic.
I think making sure that people understand the use case for each one of these is important, especially as we all move away from LiveData into the Flow (SharedFlow, StateFlow) world.

[@PhilippLackner]

Yes, I meant that flows can be a full replacement for livedata, but not the other way around. LiveData is used to represent UI state and flows can do that as well, but can also handle network calls and other suspending functionality

[@slabbor96]

[@re_allyedge]

I dont know what to type, but i have to comment

[@kishorsuryawanshi2851]

I looking for this tutorial , can you make tutorial about channel also

For any non-native-English-speakers: This weird word he is using is "coroutines" :-) I am really not used to hear this word...
