Should ModalBottomSheetLayout collapses when back key is pressed? 🤔

[nglauber]

I created this… not sure if there’s an easy way…

@ExperimentalMaterialApi
@Composable
fun BottomSheetBackHandler(
    state: ModalBottomSheetState,
    doOnDismiss: (() -> Unit)? = null,
    content: @Composable () -> Unit,
) {
    val scope = rememberCoroutineScope()
    content()
    BackHandler(
        onBack = {
            scope.launch {
                state.hide()
                doOnDismiss?.invoke()
            }
        }
    )
}

In general, nothing in Compose relies on Activity APIs (such as those for reacting to the system back button). This would be something you get for free in the upcoming bottom sheet integration with Navigation Compose: https://github.com/androidx/androidx/pull/173
