Why is it that LoadParams.requestedLoadSize returns the specified page size to LivePagedListBuilder times 3?

Question

I am creating a PagedList using:

LivePagedListBuilder(dataSourceFactory, 20)

Inside my implementation of PageKeyedDataSource, loadParams.requestedLoadSize returns 60. I tried with other numbers, and it seems that loadParams.requestedLoadSize always returns the page size I specified times three.

Anyone has any idea as to why this is happening?

Inside PagingConfig you can set initialLoadSize to the number you need to set at the first time when loading the list

Pager(
        config = PagingConfig(
            pageSize = PAGE_SIZE,
            initialLoadSize = 10 //if you need to load 10 items at the first time
        )
    )
