Hi folks, are 2 instances of function references not same ? I am calling below Composable

PermissionsScreen(
    Modifier.padding(innerPadding),
    uiState,
    viewModel::onAction,
)

I see that whenever recomposition happens because of changing uiState, the function reference is also a different instance from previous one which causes more recomposition for Composable which should not be recomposed.

Afaik, this happens because your function references the viewmodel, which is considered unstable. You could test adding @Stable to your viewmodel to verify what Im saying, Im pretty sure it wouldnt result in new functions everytime that way.

@Zoltan Demant I marked viewModel as stable but the issue persists, the only way seems to be to wrap the fun ref in a remember 😕 .

I used to store the function references before entering the Compose world (before setContent) and then pass these variables down to my screens to solve this.

class Activity... {
  private val viewModel by viewModels()
  fun onCreate(...) {
    val foo = viewModel::foo
    setContent {
      MyTheme {
        Surface {
          MyScreen(viewModel, foo)
        }
      }
    }
  }
}
