In horologist==0.2.5, the NavGraphBuilder.scalingLazyColumnComposable is deprecated, i shall use the listComposable

@Deprecated(
    "Use listComposable"
)
public fun NavGraphBuilder.scalingLazyColumnComposable(

In the nav example, NavGraphBuilder.scrollable has replaced NavGraphBuilder.scalingLazyColumnComposable , what is the difference between listComposable and scrollable ? The only listComposable which I can find in NavGraphBuilder is lazyListComposable . Thanks for any hint in advance.

Sorry, I should have put better explanations in the kdocs.

[yschimke]

The scalingLazyColumnComposable wasn't a good name, scrollable was much closer to existing navigation dsl.

[yschimke]

These functions give you a state object that is linked to an existing position indicator.

[yschimke]

So scrollable is ScalingLazyListState, listComposable is LazyListState.

[yschimke]

I'll write up a cleaner sample of scrollable and post it here.

[yschimke]

While documentation is sparse there are samples in the horologist/sample module for all of these

[yschimke]

listComposable is a typo! Should be scrollable, there is also lazyListComposable and scrollStateComposable

[yschimke]

This shows a comparison of the built in composable, scalingLazyColumn, and scrollable https://github.com/yschimke/horologist/blob/8a47a9bd7bce3b8ca65424da03cf40bb8c34d7[…]n/java/com/google/android/horologist/scratch/ScratchActivity.kt

Compared to scalingLazyColumnComposable, it lays out from the top, without providing a custom scrollStateBuilder. And configures the other params correctly.

[yschimke]

Compared to composable, it also wires up PositionIndicator and TimeText scrollAway.

@yschimke Thanks for your hint. This is fantastic, i got it now.

You can configure initial layout with a factory param.

scrollable(
            route = "menu",
            // optional method to configure initial layout
            columnStateFactory = ScalingLazyColumnDefaults.belowTimeText(
                rotaryMode = Fling,
                firstItemIsFullWidth = false
            )
        ) {
            com.google.android.horologist.compose.layout.ScalingLazyColumn(
                modifier = Modifier.fillMaxSize(),
                columnState = it.columnState,
            ) {
