I know I'm probably jumping the gun a bit with the navigation updates n 1.6.10-beta01 (and realise it's experimental ) but should argument passing work right now?

[Stylianos Gakis]

I can’t find it right now but I’ve seen somewhere someone mentioning that for iOS there was something wrong with some types of argument passing. I am trying to find more about it now.
FWIW this sample https://github.com/MatkovIvan/nav_cupcake is something that does work so you can give a look there to see if you are doing something differently perhaps?

[John O'Reilly]

yeah, have been comparing to that but it doesn't actually pass any arguments

[John O'Reilly]

maybe doing something basic wrong here....hacking together something and have for example

composable(route = "details/{countryName}") { backStackEntry ->
}

and then

navController.navigate("details/${country.name}")

[John O'Reilly]

and get this error then (in Compose for Desktop app in this case)

[Stylianos Gakis]

Does it help in any way if over at
composable(route = “details/{countryName}“) you also pass in there the navType explicitly? Not sure if the API for the KMP version is the same but if it is, something like this

composable(
        "details/{countryName}",
        arguments = listOf(navArgument("countryName") { type = NavType.StringType })
    )

[John O'Reilly]

yeah, I tried that as well

[Stylianos Gakis]

And if this also does not work, how about trying to use it as an optional parameter? Just for the sake of trying

composable(
        "details?countryName={countryName}",
        arguments = listOf(navArgument("countryName") { type = NavType.StringType })
    )

and maybe there was some API to say that it’s nullable? I can’t find smth right now

[Stylianos Gakis]

Oh also, what if you add a defaultValue like

navArgument("...") { defaultValue = "somethingHere" }

does that change anything?

[John O'Reilly]

tried those but same result

Arguments will need https://github.com/JetBrains/compose-multiplatform-core/pull/1277

[John O'Reilly]

ah, cool, thanks

[John O'Reilly]

I'm probably missing something basic but trying latest dev versions (which I thought would include above commit) but that's still not working. Using 2.8.0-dev1593

[John O'Reilly]

maybe some additional changes were needed on top of that

[Ian Lake]

There definitely were a few more fixes done after that one, namely https://github.com/JetBrains/compose-multiplatform-core/pull/1289

[John O'Reilly]

ah, perhaps that might be included in next dev build
