The ULTIMATE Guide to Sharing Data Between Screens in Jetpack Compose

Helpful as always, Thanks!

Nice. Very clear 🙂

your english so fast, please make it slow

In my current organization we use Singletons inside Repository to share users login data between different viewmodels, and they never experience any issue with that. I still don't understand why are you saying to avoid using Singleton classes to share data between. It is usuful when we need to access user's details in different pages.

how to properly share with activity please tell me

what about Preferences DataStore?

Hi Phillip,
Can we have shared viewmodel and individual viewmodel for on one onboarding screen composable at same time?

In SharedViewModel approach, how can I reset the viewModel once I leave "personal_details" route?, it's always loading previous data onceI got back into it again.

I'm sharing a viewModel between a regular composable and a sheet, but the UI doesn't update when I change the sharedState in the viewModel from the sheet. How can I make it recompose when the value in the viewModel is updated?

Hey Philipp , what about using compose destinations ?

In what order shall we take all your courses?!

I like using raamcosta destinations for compose, it really makes things easy. It alow passing data between @Composable's, but after this I can initialize my ViewModel with the value.

Hi Philipp, I have a question about docker. Do we (android dev) need to learn docker or it just nice to know

It seems to me that data binding in xml layout projects is easy, but it more hell then compose

How to send parcelable object to start destination

It is great that put the source code of the video. thanks

Thanks

Another "con" of using navigation arg is that you need to make sure the string is URL encoded. I said con with quotes because you can handle this pretty easily, but sometimes you forget to do that and can spend significant of time to find out why something isn't working as expected.

Please make video on Oauth2 Authentication with Webview using Jetpack compose

How the CallBackUrl retrieved from the api and retrieve access token to make api calls.

I am using hilt view model with compose destinations, pretty neat

Im still hard to understand navigation in compose :(

Can we share complex object data without using SharedViewModel ?

On the last option is using sqDelight a choice for Kotlin Multiplatform Mobile?

Hi Philipp, first thank you for the great tutorials.I have a question if you have time?

In the last (persistent storage) example, if we want to clear the session every time the application is closed / destroyed, but we want the session to persist through the lifetime of the app, where is the appropriate place to clear it? Isn't onDestroy() called sometimes during process death?
Thank you again!

Hi Philipp. Very helpful video as always. I have a question: why are you using shared preferences instead of data store?

When you try jetpack compose multiplataform ?

does passed intent arguments survive process death?

I really love the way you demonstrate thing ♥
but I think you should add the video to the compose playlist so we can find it easily

I wish there was a better way of writing jetpack navigation better :\
anyway thank you for this lovely guide.
is there a difference between @Singleton and object in kotlin?

How to restore state of FirstScreen if we click on Back btn at SecondScreen?

How to pass data to the previous screen
Eg: I have two screen first screen is to show the list of some items from database and second screen is used to create an item. When I create an item from the second screen I want close that screen and show the updated list in the first screen

how can I pass nullable value? for example, I need to pass Long (as LocalDateTime), and sometime this value can be nullable. If I pass null for that value, my application is crashing, because it's an exception about wrong navigation, can't find route

One question, why do we have to redeclare a new mutable state in viewmodel and assign it to original stateflow. Is there any issue if create a stateflow in viewmodel and directly access it from composables? As long as i make sure that i am not writing anything to the state, is it fine?
Ref: private val val sharedState = MutableStateFlow( value: 0)
sharedState = _sharedState.asStateFlow)

Thanks

Thanks for sharing your knowledge 👍. As a beginner, I always used the first option to pass parameters between views. Now I can start testing different ways 😄

Hi Philipp, love your videos. I have a question here, in your few previous videos you use raamcosta library as a navigation tool and lately I've seen you stop using it and I saw it also seems to provide an easy way to share data since it can share reference data. What disadvantage you discovered that made you stop using it?

Hello Mr.Pilipp
Could you make an app with multi-module and navigation, and the app consists of two types of user.
