Loads the sessions by pages of 10, instead of loading the whole list immediately.
This is meant to look at how the Apollo Kotlin pagination system can be implemented in a real project.
Caveat: the pages are based on the contents of the list: when getting the first few items, we only know about Day 1, and only when scrolling to the end of Day 1 do we know that there's a Day 2, and the pager gets updated. Because of this, this can't be merged and I'll close the PR right now - at least it's a reference at how to use the pagination system that will be in the PR history.
The steps were:
depend on the incubating artifacts
update extra.graphqls
2.1 mark sessions as embedded
2.2 mark sessions.first and .after as pagination args
2.3 mark pageInfo as embedded
implement a MetaDataGenerator to keep track of endCursor and after
implement a FieldMerger to merge the nodes lists
watch the sessions, so the UI is refreshed when a page is appended
add a fetchNextSessionsPage fun and call it from the UI when reaching the end of the LazyColumn
Note: steps 2-4 would have been simpler if the schema were following the Relay pagination spec - the rest would have been the same.
