Steps to Reproduce or Code Sample to Reproduce:

data class SomeTypeSafeId(val value: String)

    itemsIndexed(
      items = …,
      span = …,
      key = { _, state -> state.id /* Where id is SomeTypeSafeId */ },
      contentType = …,
    ) { index, model -> … }

In the example above, because SomeTypeSafeId cannot be saved to a Bundle (not Serializable, not Parcelable, etc.), the app will crash when evaluating the key.

It would be great if there were a Compose Lint rule that verifies that the return type of the key lambda can be saved to a Bundle to help prevent runtime errors.
