 /**
  * To learn more about how this test handles Flows created with stateIn, see
  * https://developer.android.com/kotlin/flow/test#statein
- *
- * These tests use Robolectric because the subject under test (the ViewModel) uses
- * `SavedStateHandle.toRoute` which has a dependency on `android.os.Bundle`.
- *
- * TODO: Remove Robolectric if/when AndroidX Navigation API is updated to remove Android dependency.
- *  *  See b/340966212.
