created issue #1

Jun 11, 2024 06:23PM

Component used: Navigation: androidx.navigation:navigation-compose
Version used: 2.8.0-beta02

Have destination object with enum
Add the destination without typeMap with that enum.

Per Ian's comment here https://issuetracker.google.com/issues/346505952#comment2 it should not be needed.

	@Serializable
	data class IssueEnum(
		val priority: Priority,
	) {
		enum class Priority { Top, Normal }
	}

Repro here: https://github.com/hrach/navigation-compose/commit/6342c95cc0c57a5e8598f92241d59a658c538071

remove the type map for IssueEnum destination
run demo app

                 java.lang.IllegalArgumentException: Cannot cast priority of type dev.hrach.navigation.demo.Destinations.IssueEnum.Priority to a NavType. Make sure to provide custom NavType for this argument.

I got the same issue as #4, and it's still here in 2.8.0-beta07.

Even if regular enums are implicitly Serializable, you still need to add it or the issue Ensure that the serialName for this argument is the default fully qualified name will appear.

package org.jdc.template.ux.test

@Serializable
enum class TestEnum {
    ONE,
    TWO
}

@Serializable
data class TestRoute(
    val testEnum: TestEnum
)

You will also need to specified type in the declaration of your route:

composable<Route.TestRoute>(
    typeMap = mapOf(
        typeOf<TestEnum>() to NavType.EnumType(TestEnum::class.java)
    ),
) {
    ...
}

During my investigations, I've found that if you declare it like this:

package org.jdc.template.ux.test

@Serializable
data class TestRoute(
    val testEnum: TestEnum
) {
    enum class TestEnum {
        ONE,
        TWO
    }
}

It will work on non-minified code, but it won't after minifying and you will get same error as before.
