I have a class that is marked @Immutable but compose metrics reports it as unstable. Am I doing something wrong here? I think this only started happening when I refactored the class to a shared package

[vide]

package app.shared

@Immutable
data class MyImmutableClass(val foo: Foo)

package app.main

@Composable
fun MyComposable(param: MyImmutableClass) {...}

Results in the following metrics:

restartable fun MyComposable(
  unstable param: MyImmutableClass
)

Resolved! I had to add androidx.compose.foundation to the shared package and import androidx.compose.runtime.Immutable instead of javax.annotation.concurrent.Immutable which Android Studio recommends first 😄

In case you weren't aware, you can make sure it won't suggest javax.annotation.concurrent.Immutable by putting it the list found at Settings → Editor → General → Auto Import → Exclude from auto-import […]. I've found this very useful for Compose. simple smile
