tanquery 0.5.0

TanStack Query for Dart. Automatic caching, stale-while-revalidate, background refetching, mutations with optimistic updates, infinite queries. Pure Dart - no Flutter dependency.

0.4.0

Bug Fixes

• Error reducer no longer sets isInvalidated: true -- Matches TanStack Query behavior. Previously, errored queries were always marked invalidated, causing aggressive refetch loops on focus/reconnect for queries that consistently fail. Now the isInvalidated flag is preserved through errors.
• invalidateQueries(refetchType: QueryTypeFilter.all) now correctly refetches all queries -- Previously dropped the refetchType parameter and defaulted to active only.
• refetchQueries() no longer leaks futures for paused queries -- Now checks paused state before initiating fetch instead of after.

Improvements

• Query._abortSignalConsumed properly wired to Retryer.isAbortSignalConsumed -- removeObserver() now correctly chooses between cancel(revert: true) and cancelRetry() based on whether the abort signal was consumed by the query function.
• isDisabled() simplified -- Removed tautological branch that always returned false.
• Unsafe null assertions removed -- QueryCache config callbacks (onSuccess, onError) now accept nullable data/error, preventing runtime crashes with nullable TData types.

Dead Code Removed

• Removed isStatic() method (always returned false, never called)
• Removed setCacheNotify() method (never called externally)
• Removed FetchDirection enum (unused across entire monorepo)
• Removed EventType.observerResultsUpdated and EventType.observerOptionsUpdated (never emitted)
• Removed StaleTime.zero and StaleTime.isZero (never used)
• Removed unnecessary late keyword on QueryKey.queryHash
