Features
-
Pagination implements pagination logic for the data from abstract
PagedListDataSource. - Managing a data loading process using Pagination asynchronous functions:
loadFirstPage,loadNextPage,refreshor their duplicates withsuspendmodifier. - Observing states of Pagination using
LiveDatafrom moko-mvvm.

Installation
root build.gradle
allprojects {
repositories {
mavenCentral()
}
}project build.gradle
dependencies {
commonMainApi("dev.icerock.moko:paging:0.7.1")
}Usage
You can use Pagination in commonMain sourceset.
Pagination creation:
val pagination: Pagination<Int> = Pagination(
parentScope = coroutineScope,
dataSource = LambdaPagedListDataSource { currentList ->
extrenalRepository.loadPage(currentList)
},
comparator = Comparator { a: Int, b: Int ->
a - b
},
nextPageListener = { result: Result<List<Int>> ->
if (result.isSuccess) {
println("Next page successful loaded")
} else {
println("Next page loading failed")
}
},
refreshListener = { result: Result<List<Int>> ->
if (result.isSuccess) {
println("Refresh successful")
} else {
println("Refresh failed")
}
},
initValue = listOf(1, 2, 3)
)Managing data loading:
// Loading first page
pagination.loadFirstPage()
// Loading next page
pagination.loadNextPage()
// Refreshing pagnation
pagination.refresh()
// Setting new list
pagination.setData(itemsList)Observing Pagination states:
// Observing the state of the pagination
pagination.state.addObserver { state: ResourceState<List<ItemClass>, Throwable> ->
// ...
}
// Observing the next page loading process
pagination.nextPageLoading.addObserver { isLoading: Boolean ->
// ...
}
// Observing the refresh process
pagination.refreshLoading.addObserver { isRefreshing: Boolean ->
// ...
