Support Paging Library with DataSource

Feature Request

Description

LiveData with Fuel is awesome integration. I think it will be also great with Paging Library for api pagination. (DataSource, PagedList)

Proposed Solution

data class User(val key : String)
// ...

val pageSize = 20

val staticParams = listOf("limit" to pageSize)
val request = "https://...".httpGet(staticParams)

val onLastItemLoaded = { last : User -> listOf(*staticParams, "next" to user.key) }
val config = PagedList.Config.Builder().setPageSize(pageSize).build()

val source = request.dataSource<String, User>(dynamicParams : onLastItemLoaded)

val pagedList = source.toLiveData(config)

// or

val pagedList = request.livePagedList<String, User>(config, dynamicParams : onLastItemLoaded)

Alternatives I’ve considered

I have no idea. I think it can’t append query parameters dynamically.

Additional context

Thanks.

But out of the top of my head, I don’t think it fits well into the Fuel repo though. I think it is more like a child repo where it should have someone who really commits to this to maintain it. I would rather leave Fuel (even the extension) as it is unless we have something really ubiquitous.

Hi there,

Can you link to DataSourxr and PagedList and the Paging library?
