I'm going to continue my Navigation Compose tutorial series. And in this current video you'll learn how to pass single and multiple arguments using both argument types like Required and Optional arguments. This is a very important video in this series so I highly suggest you to watch the whole video. :)

I've been fighting with my code all afternoon, not knowing why it gave me errors when trying to passs variables from one screen to another. I came across your video and it was a life saver, I swear. The project I am developing is for college and I had to finish it literally this afternoon. You saved me, thank you so much! Great video and great explanations, cheers from Spain dude :)

What is the best way to pass bitmap between composoble screens

@stendoff2388 2 года назад

Great lesson, thanks. And how can I get the sent values for further work with them?

@sooshil Год назад

For example, if you need that id in Detail Screen, then the detail screen composable should expect it. DetailScreen(id: Int) Then just below the log statement, when you call DetailScreen, you can pass the id to the constructor.

@deceptivelysmallman Год назад

@@sooshil Amazing thank you! Really useful ^^

@gara7723 7 месяцев назад

@@sooshil I'm sorry I don't understand. I setup my composable like this: @Composable fun DetailScreen( navController: NavController, id: Int ) {...} Then in the NavGraph.kt file what exactly do I need to pass for the id? DetailScreen(navController = navController, id = )

can we use a custom class as argument?

@youprimeprime3046 2 года назад

Awesome

@StevdzaSan 2 года назад

Thanks 👊

@WilliamLindblom 2 года назад

Doesn't the use of default values in the passNameAndId() function make the usage of optional parameters redundant? It will always pass a value, so the params might as well be required as the "optionality" lies in the default values of the function. Or am I missing something?

@StevdzaSan 2 года назад

Yep that's correct. However 'optional' in that case would be not calling that function at all. And just navigating to the default route. :)

@hemantp66 Год назад

why log is called 3 times , when you click once?

@abada-s 2 года назад

we can always use required arguments and specify optional arguments in the Screen method declaration is it true?

@StevdzaSan 2 года назад

Yes if you add default parameters

@jatinvashisht4293 2 года назад

You can pass an Array.

@aishwaryabhishek1822 2 года назад

2 questions , why are the logs getting printed 3 times ? is it getting recomposed that many time ? And how to pass Parcelable objects . Great content though

@StevdzaSan 2 года назад

We don't have a much control over a re-composition process in general. "A composable function might be run quite frequently, as often as every frame of an animation." Passing a Parcelable object is not recommended. You have already seen the route structure of one screen and it's arguments. The common practice is to just pass some primitive values like id's and then from the other side, get that id and fetch the data you need(From database or even an API).

@easybusinessou 2 года назад

@@StevdzaSan sometimes we have already fetched object we only need to display in another composeable

@StevdzaSan 2 года назад

@@easybusinessou My suggestion would be to reconsider the logic of your app, and modify it in a way to have only primitive types passed as arguments. Also if you need to save some kind of object, consider adding a Shared ViewModel.

@aishwaryabhishek1822 2 года назад

@@StevdzaSan Thats a step back from current Navigation library dont you think ? I think its better to still use the current navigation and each fragment just hosts a composeView .

@markdelphi8075 Год назад

Thanks for lesson. Is it possible to send a Data class like data class Car(val model:String, val color: Int) as an argument? Thanks .

I've made a video about passing a parcelable object, check my Jetpack Compose playlist.

Can I pass data object as argument?

@StevdzaSan 2 года назад

That's not a recommended approach. Instead you need to pass primitive values, like for example only the ID of a certain object, which can be then retrieved on the other side from another screen.
