Hey, is there any easy way to create bundle from the navargs data class?

we can create args from destination ex GeneratedScreenDestination.argsFrom()

but there is nothing like

ScreenArgs(arg,arg).toBundle()

Looking at the generated code I don't think anything exists today. I guess you could go through the SavedStateHandle and then create the bundle (I've not tested it):

private fun SavedStateHandle.toBundle() = keys()
    .map { it to get<Any>(it) }
    .let { bundleOf(pairs = it.toTypedArray()) }
// or
private fun SavedStateHandle.toBundle() = keys().associateWith { get<Any>(it) }.toPersistableBundle()

// To create
val bundle = YourNavArgs("param1", "param2").toSavedStateHandle().toBundle()
// To parse
val args: YourNavArgs = YourDestination.argsFrom(bundle)

nice! i was just trying to make some parser but never thought of using SavedStateHandle first, that seems to be working perfectly so far.
I was in need of having something that could convert args to bundle due to still mixed up navcomponent with compose

saved me a lot of headache, thank you!

No problem 🙂

[Rafael Costa]

Yes this was the type of solution that came to mind as well.
Let me know if you find any limitations or issues with it 🙂

@Rafael Costa I happen to catch

java.lang.NoSuchMethodError: No static method toSavedStateHandle

from generated files for some reason.
Fails runtime

[Rafael Costa]

Is this on release build with R8? 🤔

[Robert C]

No, debug build
I can clearly see generated methods and files though

[Rafael Costa]

It’s very weird.. I don’t know what else could cause this 🤔

[Robert C]

Had one more view on that and it seems I was missing one ksp enclosure within module configuration, it seems like it overwrites files but still it is able to compile. Instead of throwing some errors.
