To build a paginated feed in Flutter, use PagedFeedDataSource to enable cursor-based pagination and auto-pagination when nearing the end of the list. It separates initial load states from next-page loading to manage infinite scroll efficiently.

Update a Flutter feed list reactively by driving feed updates through an event-bus. The pattern integrates ValueNotifiers with Commands to handle event-driven data mutations while maintaining safe proxy lifecycles.

Manage proxy lifecycle safely in a Flutter feed widget by using a dedicated proxy manager to create and release proxies. The createOnce method ensures proxies are bound correctly across the feed's life-cycle.

Yes, this paginated feed pattern supports both finite and infinite list handling. Base FeedDataSource manages non-paged finite data with safe mutations, while PagedFeedDataSource handles cursor-based pagination for infinite lists.

The best way to separate initial load and next page loading in Flutter is using PagedFeedDataSource. It specifies distinct update and next-page commands, ensuring isolated loading states for initial data fetches versus subsequent pagination.

Separate commands for updating data and loading the next page are needed to prevent state conflicts. This separation isolates initial load operations from pagination triggers, ensuring auto-pagination near the list end behaves safely.
