I’m trying to get the code from GitHub Oauth API playground://gh?code=XYZ in the ViewModel through savedStateHandler. My composable screen configuration:

NavGraphBuilder.composable(
         route = "login",
         deepLinks = listOf(navDeepLink {
            uriPattern = "playground://gh?code={code}"
         })
      ) {
         Log.d("MyLog", it.arguments?.getString("code", "nothing") ?: "null")
         //...
      }

MyLog is always nothing

I also tried to implement the NavGraphBuilder.composable.attributes parameter, but the result was the same.

I’m just getting familiar with Compose and went through the Google Code labs. https://developer.android.com/codelabs/jetpack-compose-navigation#4 – this worked as expected, but the issue is the argument is required.

I also have a WebViewScreen composable that needs a URL and that works.

builder.composable(
         route = "browser",
         arguments = listOf(
            navArgument("url") {
               type = NavType.StringType
            }
         ),
         deepLinks = listOf(
            navDeepLink {
               uriPattern = "playground://gh/browser/{url}"
            }
         )
      ) {
         //...
      }

Not sure if this can be achieved with Jetpack Compose Navigation or do I have to use the Intent approach a pass it to the ViewModel?
