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

[@lindaporsius]

Could you please make a video about Drawer/BottomNav using this lib? Especially how you would handle the selected-property of a nav-item (and the corresponding icons)

[@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.

[@magedahmed5981]

Finally .. a simple straight routing .. 😊

[@amit470]

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

[@ilyastoletov]

Just use Reimagined Navigation that has a bunch of cool features such as type-safe navigaiton and Parcelable support out of the box. Also community have the Decompose as a multiplatform solution. Both of these libraries are completely driven by community so if you prefer only official libraries it's always OK

[@vit4mint685]

Just wrapped up a project that used a lot of the old compose navigation. Looking forward to this

[@worthex_2]

Omg this feels much more satisfying to do nagivation straight with classes now. Beautiful update.

[@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.

[@rishabhsaraswat1928]

4:03 we can clearly see his happiness.

[@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.

[@supadeurali9848]

Wow wow wow.... tears in my eyes as well. So excited to try this.

[@coalacorey]

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

[@Zscor27]

Thanks for keeping us updated on new stuff. The eco system changes so fast in Android, and there really isn't many youtubers keeping up but atleast we have you :D

[@moheltanani1036]

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

[@Mexicanerie]

Amazing ! I'm already making a PR on my projec with theses improvments 😁

[@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.

[@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.

[@siftoshka]

What if I need this parameters on ViewModel?

[@TheRobertJamison]

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

[@yahussainmazloom1]

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

[@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.

[@ASTAppLab]

being as Android Native Developer appreciate 👍 you

[@quangthaita6084]

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

[@okeziokezino]

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

[@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

[@9Blurke9]

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

[@TimKaragosian]

This looks similar, but even better than Decompose. As always, thanks for sharing these great videos and quality content!

[@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.

[@joatancarlos2704]

Thank you for bringing this content in a very didactic way

[@tmjromao]

Thanks for the video. Is the bottom navigation also changing accordingly? What is needed to have screenB with bottom navigation graphs? Thanks.

[@manticomar1146]

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

[@AntliaRodriguez-d9t]

Uff faltan tutoriales asi en español, gracias a youtube por los subtítulos! Estaba buscando entender esto y solo con tu video pude

[@СергейБобошко-в2л]

The strings arguments i could pass and old style way... The interesting example will be pass a data class. Somehow somewhen i'll try.

[@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?

[@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 ?

[@bierdav]

I would be the happiest developer in compose multiplatform land, if you make a video about "scalable" Type-Safe Navigation with best practises 😊 I find it hard to structure my compose multiplatform app, because somewhere I always have to mention all the navigation routes, but what if i have 40 of them? I can't image of way that isn't completely messy with this huge amount of screens

[@youNeverThoughtAboutIt]

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

[@meidy3795]

Good information Phillip ! Thos wpuld really helped my ptoject for compose multiplatform

[@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.

[@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?

[@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.

[@samuelwakoli]

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

[@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

[@planet3a]

I once said XML way of navigating was better than Compose. Now it's getting better. 😀

[@kfirossmatityahu4295]

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

[@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? 🤔

[@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.

[@AKnght]

Is this out for Compose Multiplatform yet? Great video!

[@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()

[@MultiDeivas]

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

[@chaitanyapenjuri]

How can we navigate to pop backstack from screenB to screenA with some arguments, please explain

[@danielreinhold8475]

Looks pretty nice, but in my opinion compose destinations by raamcosta is still easier to use & maintain.

[@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.

[@Revitalish]

i'm trying so hard to understand where was the problem in passing arguments to screens till now? i mean I haven't tried passing anything except for the ViewModel instance. was that wrong? and if so, then how do I share same ViewModel instance with multiple screens (including nested navGraph)?

[@slyene6202]

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

[@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?

[@lazydeveloper7753]

How do I navigate between two graps containing two screens each usi g type safety? Im confused. Please make a video on this.

[@BugraKaraahmetoglu]

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

[@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...

[@santyas]

Great Video!!! How do you retrieve args from the destination viewModel directly? If I use savedStateHandle inside viewModel still needs to safe the possible null argument using ?: or !!

[@portusdelphini]

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

[@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

[@EdwinRebolledo]

We can use it in prod apps ? its on alpha or you recommend to use it from now on

[@diabetesatuniversity]

Thanks this is helpful. Love your videos.

[@kuromujou1346]

looking forward you make a video about this but with multiple nested graph. im newbie and im so confuse right now.

[@krasavec7088]

Is it possible to use that with nested graphs?

[@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.

[@MrMacromicro]

Thanks philip ,you are really amazing.

[@ntikomathaba2662]

Is this the best navigation for Compose Multiplatform?

[@Lucky_PhilB]

Havent had the chance to play with this yet. How does it deal with deeplinks? And is this implemented for kmp compose?

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

[@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.

[@yanneckreiss]

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

[@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.

[@ryantcb]

Really appreciate your videos. Moving over from iOS to learn JC and OMG we spoiled with Xcode. All this fluff that has to happen around implementing simple tasks like navigation. Genuinely unless they make working in the Android development more user friendly, I can see new devs just giving up and sticking to iOS. Such a headache. If it wasn't for your videos I wouldn't have made it past "Hello, World(Android)". Thank you

[@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

[@pablovaldes6022]

Still a lot to improve. Dynamic load of graph in other libraries or modules, without the need to load all them upfront.

[@mehdiparsaei1867]

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

[@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.

[@Matthew01369]

Hi there, did you manage to fix it? It's happening to me also

[@vsv8161]

Same problem

[@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

[@Alchemist10241]

with this approach how can we do a shared transition between screens?

[@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.

[@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?

[@ayitinya]

with this, do you create a separate file called and put in all data classes and objects? what would be a clean way to keep the screens? I have also thought of having a sealed class called Screens and then throwing all screens in there. curious to know what you suggest

[@ЕвгенийПавлусенко]

I personally replaced sealed class with sealed interface and moved all serialized objects & classes to it

[@MrMindfullness]

I have purchased Essentials course. Will this be incorporated in the course as well?

[@mark-147]

Any tips on naming? I already use FooScreen for the actual composable UI.

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

Nice but how can we achieve this if we are using dependency injection and need these args in a view model?

[@PhilippLackner]

They're still part of saved state handle

[@random-videos96]

@@PhilippLackner yes but only single args as a string. What if we need the whole data class as a param in a view model? I guess assisted injection come to the rescue
