Components used:

androidx.paging:paging-runtime-ktx:3.0.1
androidx.paging:paging-compose:1.0.0-alpha12

Will be describing issue with Jetpack Compose example:

Currently we're forced to use

val isRefreshing by remember { derivedStateOf { games.loadState.refresh is LoadState.Loading } }
val isErrorOnFirstPage by remember { derivedStateOf { games.loadState.refresh is LoadState.Error } }
val isError by remember { derivedStateOf { games.loadState.append is LoadState.Error } }

Inside the composables. It would be great if we could observe these events in places where we are declaring our Flow<PagingData<Value>>, Pagers. This would allow to propagate these important events from upside down, not the other way around.

The only workaround I can currently see ( if one doesn't want to emit these events from the view layer ) is passing lambdas into the PagingSource. But this should create quite an overhead.

Any enhancement of the Paging API's would be a big plus.
