Hey!
Would it be safe to call retainedComponent in the root function of a Compose Multiplatform app?

@Composable
fun App() {
    val rootComponent = remember { retainedComponent{ context -> DefaultRootComponent(context) } }
}

Goal: To have a single entry point for all targets.

[Arkadii Ivanov]

Nope, not safe. On configuration change the remember {} block will run again.

[Nacho Ruiz Martin]

So retainedComponent should always be called in the main function of each platform, right?

[Arkadii Ivanov]

It's only available on Android, since the concept only exists on Android.

[Arkadii Ivanov]

It's designed to be called from onCreate callback

[Nacho Ruiz Martin]

Ah, that makes sense.
I was searching for a way to instantiate the Root component in the common code.

[Arkadii Ivanov]

Yeah, it's better to instantiate the root component outside of Compose.

Thanks, Arkadii 🙂
