7:17 He sounds so happy about it 😭

[@WakeupDev.]

yea... I felt that in his voice 😄

[@farfar5828]

😂😂 I felt that too

[@KevinMeneses]

X3

[@BSS_00]

its like every developer after a new good feature

[@ilyastoletov]

Cause this feature reduces hundreds of lines of boilerplate parsing arguments, ensuring they're not null, etc...

[@Shengdanya]

Yes. Yes. Yes. Omg. Tears of joy. Really needed a new way!!!!!

[@ayitinya]

This is actually the best news in android i've heard in a really long while

[@annaberkovitch85]

Philipp, I've no words!!!! Thank you for brightening my day! But mostly thank you for the truly TREMENDOUS amount of work you're doing to bring all those updates to us in a manner that's both timely and incredibly clear. Just... Thank you!!!!

[@PhilippLackner]

🙌❤️

[@nanonkay5669]

2 reasons why I started and stopped Android dev within a year: 1. Lack of a package manager that handles all package installations, they're dependencies and versions without having to manually do it every time and manually tweaking package and dependency versions 2. Navigation between screens The second one seems to be solved. If the first one gets solved, I'd be back to Android dev in a heartbeat

[@rishabhsaraswat1928]

4:03 we can clearly see his happiness.

[@JackCheungShingKit]

That JSON serialization is how I did before for passing argument. Though my approach on serialization & deserialization boilerplate can be ugly. Agree that it is a great improvement. I wish they made this available since the beginning.

[@Jessewb786]

I was using Circuit and it's own navigation, so I've been making use of type-safe screens with painless parcelable arguments for quite a while. It's nice to now see this present in the official library.

[@MatthewSmith-mt3kz]

The demo is a pretty simplistic, but a good intro into the new Nav feature. In the real world you'd be getting the screen argument from savedstatehandle. Keep up the good work Phillipp, your videos have saved me hours. Thank you.

[@magedahmed5981]

Finally .. a simple straight routing .. 😊

[@amit470]

Such a relief, I need this to be in compose stable

[@moheltanani1036]

If you were in tears, I'm crying right now hehe. Love it, thanks a lot!

[@raeesmohit01]

It was really a big problem for beginners for me to change the screen and you made it easy now

[@geanbrandao4987]

It's so easy now. Thank you for bringing this content to us! Keep up the great work, hugs from Brazil.

[@coalacorey]

Finally! As soon as the stable release is out I will implement it.

[@yahussainmazloom1]

Finally some good updates, finally so much relief after this update

[@vengateshm2122]

There was a crash when we try to pass custom type like User(val id: Int, val name:String, val isPremium) in 2.8.0-alpha08 version which is fixed recently in version 2.8.0-beta01.

[@ASTAppLab]

being as Android Native Developer appreciate 👍 you

[@siftoshka]

What if I need this parameters on ViewModel?

[@9Blurke9]

Now we need another navigation video to compare all the options with pros and cons for each 😄

[@TheRobertJamison]

Even more relevant as of July 3rd, since JetBrains released version 2.8.0-alpha08 of their KMP compatible version of navigation-compose.

[@quangthaita6084]

Thanks who created this, thanks Phillips ❤ That's what we're waiting for

[@normno]

Так забавно наблюдать, как мои любимые yoytebers выпускают обзоры на новые функции библиотек android и kmp примерно в одно и тоже время и у каждого свое красивое решение использования.

[@MateuszKowol-nu8lr]

Still nice improvement however the main advantage of f.e. voyager is that you do not need to declare the navHost and its all routes. Voyager allows you to just jump from ScreenA to ScreenB without declaring it in your navHost. Google's navigation is still kinda similar to the fragment navgraph but without the childlish arrowing thing.

[@douglascf2]

Thanks for the video! So exciting! I have a question, does it automatically work with SavedStateHandle in a ViewModel?

[@jeonie9682]

I did today and worked well. but you should use the method now like "SavedStateHandle.toRoute" not just "savedStateHandle" in a ViewModel.

[@okeziokezino]

Philip my guy, this is awesome... love all your work

[@paulklein649]

do somebody still wish to work for google and develop shitty frameworks and libs and maybe correct them 2 years later to be somewhat usable? I have the feeling that every dev-product google provides is garbage if jetbrains is not involved in the development

[@BigCarso]

What about Compose? Probably the best UI framework in existence

[@paulklein649]

@@BigCarso yeah. You mean jetbrains compose just relabeled for android

[@BigCarso]

@@paulklein649 ok you have no idea what you're talking about. Compose was developed by Google team, not Jetbrains

[@stijndcl]

​@@paulklein649 ? JetBrains made compose multiplatform years after the android version, and most of it is a 1:1 port of jetpack compose. Not sure what you're on about with that.

[@MO1NKHAN]

OMG, I wish this could have come earlier. In my first app I have spent so much time and effort just to handle navigation without relying on 3rd party libraries. I have an e-commerce app running in production with lots of screens hanging on those route strings. It's time to refactor and remove all that boilerplate code.

[@joatancarlos2704]

Thank you for bringing this content in a very didactic way

[@filipmanevski9872]

Can you make a video on how to implement this way of navigation, using a navigation drawer for example or a bottom nav bar?

[@manticomar1146]

The questino is in my view model how would I use savedStateHandle to extract the parameters?

[@kfirossmatityahu4295]

So actually they got the motivation from Voyager!? (pushing classes as "screens") great!

[@aiyuayaan]

Thanks @Philipp Lackner, one thing I have to mention is we can't send empty string as value, I am using 2.8.0-beta01.

[@SunAndMoon-zc9vd]

With "empty string" do you mean: 1.a text with no characters; like "" 2. or do you mean undefined 3. or do you mean null

[@aiyuayaan]

@@SunAndMoon-zc9vd I mean "" this

[@MultiDeivas]

It seems like the NavHost causes memory leaks on configuration changes, lovely :)

[@youNeverThoughtAboutIt]

Shouldn't we store those composables for different screens in separate files? Maybe I'm just thinking in old Fragment style though

[@MonichGPT]

Where is type-safe bottom sheet navigation? I don't see it in the docs. So for now we can't use type-safe navigation at all?

[@AKnght]

Is this out for Compose Multiplatform yet? Great video!

[@darknjko]

Thanks again for that demo. Spot on, as always 👍 Originaly, it seemed that the routing library was made to handle all routes as deeplinks. I wonder how deeplinks will work with that new approach? Should we write a deeplink handler that would reroute the user to the proper screen? 🤔

[@yanneckreiss]

Haha I can relate to your joy about this update so much 😂Great video!

[@oneclickmobiledevelopers7825]

Which theme you are using in the android studio, It's awsome..!

[@LEEJIHUN]

I was wondering how to migrate the code when using it with BottomNavigation or NestedNavigation

[@diabetesatuniversity]

Thanks this is helpful. Love your videos.

[@samuelwakoli]

Is Kotlin Multi-Platform industry ready? Can I migrate my Flutter project to KMP?

[@loklok2003]

But how can I check the currentDestination using Type-Safe Navigation? For example, I would like to check the selected item in the BottomNavigation which was previously done using a string. However, with Type-Safe Navigation, I'm unable to cast NavDestination to a Serializable object.

[@upbeatsarcastic8217]

This is most exciting Compose feature to date imo. Having just finished a Compose app, navigation was the ugliest thing to deal with by a long way.

[@MrMacromicro]

Thanks philip ,you are really amazing.

[@ordnavile]

Very good, my project is in its final stages. I'm going to take advantage and refactor it to be cleaner. Thank you very much friend.

[@kurtispalu]

How do I reference the object into a navigation drawer argument? I keep getting crashes when I try to use a var to carry the object name into the navigation drawer item. Thanks

[@rahathossainhimel7177]

Finally. Thank you Philipp

[@PratikSahu18]

Will the object be injected to viewmodel like it used to inject with the parameters when using hilt?

[@BorisJakubov]

private val ScreenA = savedStateHandle.toRoute()

[@BugraKaraahmetoglu]

Could you please explain how we can safely integrate vertex AI into the application with Google Cloud Console. I need this urgently.

[@wilkq1110]

hi Philipp, is nice video, Could you please tell us if this new approach to navigation works well as well with bottom bar navigation ?

[@krasavec7088]

Is it possible to use that with nested graphs?

[@Pulkit__7]

KotlinX Serialization brings back old memories from 2019

[@portusdelphini]

In a prospect of front end routing this looks like a hell. Still a question why it's so complicated?

[@arthurabreu1904]

Aaaaand thanks again for sharing man! 🎉🎉🎉

[@WakeupDev.]

Lucky me.. I just started doing compose and KMP, so I haven't suffered like you 😄 I see some cool changes

[@JamesShisiah]

Haha, me too.

[@radheshyampatel5578]

I am Big fan of yours video 🎉

[@ronalkspdev]

hay un error en el OnRestart cuando la activity se pausa por poca ram y se ejecuta el onRestar manda error de restoring back stack alguien le paso?

[@siddharthshakya09]

I have deployed 2 production apps which are used by Big Enterprises. I have used voyager and it's seamless till now. Is it worth moving to official library?

[@slyene6202]

Please, if you have such code, let us see how to create custom nullable arguments (NavType's)!

[@cfa532]

I am using ver rc01 and met a strange problem when passing two arguments in a data class object. The 2nd argument sticks the value of its first time usage, never changes in the afterward calls. I have to use the old way to get around this.

[@Dizzyslizzy]

I used a json + simple kotlin class to get around this. shouldn't need to tho...

[@ntikomathaba2662]

Is this the best navigation for Compose Multiplatform?

[@resitsahin7787]

Hi Philip, can you make a video about drag and drop of lazy column, i have stuck there. It seems they have recently added this capability.

[@andrianbantero3462]

Gemini AI suggestions in Android Studio Jellyfish

[@rifatkhadafy9786]

but what will happen if theres multi module, like screen from Module A want to navigate to Module B and with Multiple Different Object the problem i cant import directly Module B to Module A it will cause circular dependency

[@PhilippLackner]

@@rifatkhadafy9786 navigation setup doesn't belong in any module that's not the app module. For learning this properly, check my essentials bundle: pl-coding.com/android-essentials-bundle

[@Ayor88]

I've add it to my project and it works really well but now I'm flooding with logcat message : "updateAcquireFence: Did not find frame." This doesn't crash the app or anything, but it's really annoying.

Thanks! How about this code snippet? @Serializable sealed class Screens { data object Main : Screens() data class Settings(val username: String, val emailAddress: String) : Screens() }

[@MrBzik1111]

I wonder how other libraries (mentioned in the comments) can get use out of Parcelable. For KMP. I thought It was only android thing

[@EngOsamaMohsen]

Is that work in KMP ?

[@sijanneupane]

how to use this with navGraph? since it asks for string in the start destination. and we're passing object here.

[@PhilippLackner]

Navgraphs are also objects with this change

[@quangthaita6084]

I realize that the new Compose Navigation version 2.8.0-alpha8 makes navigation with bottom navigation bar lag

[@manjodh]

I am using this approach with shared element transition. When i am navigating from screen A to B. When entering in Screen B I click back button before transition complete the app is getting crashed.Why it is happening?

[@gloooooom6229]

hi! how would i do it if i have 2 UI sets for 2 usertypes? i have a radiobutton on the signup to identify them. how can i navigate them to the right set of UIs i already have my bottomnav that has 5 screens

[@Jon88938]

Isn't it still not ideal that you have to do NavBackStackEntry.toRoute()? like you could accidentally you use the wrong class surely?

[@WilliamAlexandersProfile]

They fixed navigation. Joy

[@patsnow1066]

Need this in KMM!

[@deepaksingh-qd7xm]

Now I will learn it I has paused my learning

[@unknownBoy85lover]

The android SDK developmented by Google need a lot of changes in most of layers this API's are from them

[@Daaaaaaavid]

How does this look like in a big app with 50+ screens?

[@Guilo583]

thanks for video. Is this new lib support compose Multiplatform ?

[@zeroarst]

Is there a way to gradually migrate to this meanwhile still keep the current navigation in xml? Simple the current project has large codebase and too difficult to migrate it in one shot.

[@СенчуринНиколай]

It looks fine with two screens, what about popBackStack , popupTo etc, like in fragments ? When nav logic becomes more complex

[@PhilippLackner]

Works just as easy

[@michakazmierczak4464]

how to use this with multi module project with feature modules not depending on each other just like android recommends?

can i pass model into screen B?

What an improvement!

[@뚜릅-i6c]

Can I use the library normally in kmm? Is it superior to voyager and decompose?

[@sw_a_ppy]

Pls make more on this

[@laughforlife4569]

Then how can we use it with deep link?

[@5erTurbo]

Not completely sure why they need type in `toRoute()` function. I guess it could also be avoided.

Heya, Guys, for CMP it does not work, maybe someone have an example?
