In Jetpack Compose, when something needs cleanup, the usual reflex is DisposableEffect.
But what if the composable didn’t have to own that responsibility ?
I’ve just published a short article about RememberObserver, a Compose API that can make some designs cleaner by letting remembered objects react to being remembered and forgotten by the composition.
It’s one of those APIs that many people don’t use, even though Compose itself relies on the same idea internally.

Do you know if using RememberObserver gives any performance benefits over DisposableEffect? Or maybe quite the opposite?

[Yves Kalume]

DisposableEffect is essentially a thin wrapper around RememberObserver; there’s no real performance difference.
