A smooth, non-blocking loader for long lists and grids. As users reach the end, a spinner row with Loading… appears and fetches the next page without jumping the scroll. Supports page/offset/cursor pagination, prefetch thresholds, error retry, and a graceful “No more results” state.

Functionality

• End-of-list trigger (sentinel/intersection) with prefetch threshold

• Pagination modes: page/limit, offset/limit, and cursor-based APIs

• Sticky footer loader row with spinner + status text

• Optional Load more button fallback when auto-trigger is disabled

• Preserves scroll position; prevents layout jump on new items

• Concurrency guard, debounce/throttle, and request cancellation

• Duplicate prevention & merge strategy with custom id resolver

• Empty/error states with retry; success completion “No more results”

• Works with ListView, GridView, Slivers, and nested scrolls

• Optional dim/shimmer overlay while fetching (reduce-motion aware)

• Supports infinite + pull-to-refresh combo (top refresh, bottom load)

• Virtualization-friendly; 60fps targets with large datasets

• Offline-first pattern: cache → revalidate (SWR)

• Theming: colors, typography, spacing, elevation, radius

• Accessibility: screen-reader labels, large hit targets, semantics

• Hooks/callbacks: onLoadMore, onCompleted, onError, onRetry

Use cases

• Social/news feeds loading older posts

• E-commerce category pages adding more products

• Search results that grow as you browse

• Photo/video galleries and media libraries

• Chat history viewers fetching older messages

• Admin tables, logs, and audit trails
