The interesting thing about this repository is that it implements the Paging 3 Library that has so many features that simplified complicated process creating RecyclerView with paging.
- Loading small chunk of data that reduces usage of network bandwidth and system resources.
- Built-in support for error handling, including refresh and retry capabilities.
- Built-in separator, header, and footer support.
- Automatically requests the correct page when the user has scrolled to the end of the list.
- Ensures that multiple requests are not triggered at the same time.
