flutter_query_client 1.1.0

A TanStack Query-inspired server state management library for Flutter. Handles caching, background refetching, pagination, mutations, and network-aware fetching out of the box.

1.1.0

Fixes

• Fixed race condition in InfiniteQueryController._executeFirstPage cache-hit branch — missing _filterVersion check after await Future.delayed(Duration.zero) could cause stale filter data to be emitted if setParams was called concurrently
• Fixed race condition in InfiniteQueryController._executeFirstPage pause branch — same missing version check allowed a paused state emit to overwrite state set by a concurrent setParams call
• Fixed InfiniteQueryController.loadMore not calling _startRefetchInterval() on success — polling would never start if loadMore was the first successful fetch operation

---

1.0.1

Fixes

• Removed unnecessary package:meta/meta.dart import from QueryController and InfiniteQueryController — elements are already available via package:flutter/foundation.dart
• Removed @internal annotation from handleRemount() in both controllers
• Fixed unresolved dartdoc references in QueryLogger and RefetchOnMount — replaced [Logger.root.onRecord] and [staleTime] with backtick code spans

1.0.0

Initial stable release.

Features

• QueryController — fetch and cache server data with automatic stale-while-revalidate, retry with exponential backoff, refetch on mount, and refetch on reconnect
• MutationController — user-triggered mutations with lifecycle hooks (onSuccess, onMutationError, onSettled) and optimistic cache update support
• InfiniteQueryController — paginated / infinite-scroll queries with loadMore(), hasMore, cursor or page-number pagination, and item-level cache helpers (updateItem, removeItem, appendItem, prependItem)
• QueryClient — singleton two-level cache (baseKey + serialized params) with stale-time tracking, garbage collection, and active observer registry
• QueryClientProvider — InheritedWidget for injecting QueryClient and global QueryDefaults into the widget tree
• QueryProvider / InfiniteQueryProvider — StatefulWidget wrappers with remount detection via TickerMode for IndexedStack and Visibility support
• QueryBuilder / InfiniteQueryBuilder — reactive builders that rebuild on state changes
• QueryListener / MultiQueryListener — side-effect widgets that respond to success and error without rebuilding the tree
• QueryState — Freezed-based immutable state with status, fetchStatus, isStale, and convenience getters
• NetworkConnectivityObserver — true L7 connectivity verification (HTTP HEAD), debounced events (500ms), lazy initialization
• QueryDefaults — global configuration for stale time, gc time, retry count, retry delay, refetch interval, network mode, error transform, and logging
• QueryLogger — opt-in structured logging with customizable handlers
