android - How to preload Initial data earlier in Jetpack Paging with Pager and PagingConfig? - Stack Overflow
I'm working with Jetpack Paging to load data from a Room database using Pager and PagingConfig in my ViewModel. I want to preload data earlier before it's actually needed by the user, so the data appears faster when they load at first time.
val pager = Pager(
config = PagingConfig(
pageSize = 10,
prefetchDistance = 3, // Prefetch data 3 pages ahead
initialLoadSize = 10,
maxSize = 16
),
pagingSourceFactory = { chatUserDao.getAllChatUsersRawAsPager() }
).flow.cachedIn(viewModelScope) // Cache the flow in the ViewModel scope
@Query("SELECT * FROM chat_users ORDER BY timestamp ASC")
fun getAllChatUsersRawAsPager(): PagingSource<Int, ChatUser>
I need to load items earlier even if user is not collecting. When i navigate to the screen it is started collecting. But i need to collect them before navigation. I used collect() not worked as i am expected for earlier loading. I know it it will be collected only on lazycolumn attached with val chatUsers = viewModel.pager.collectAsLazyPagingItems() but i need to collect them earlier. How help me?
