Metadata

A backend-agnostic persistent task queue for Dart and Flutter with retries, backoff, concurrency control, and recovery.

0.2.0 #

Add DurableQueue.retry to re-queue a failed or cancelled task with a fresh attempt budget and an optional replacement retry policy.
Add DurableQueue.delete and DurableQueue.purge so finished tasks no longer accumulate in storage forever. purge filters by terminal status and age.
Add DurableQueue.close and isClosed to stop the worker and close the events and storageErrors streams.
Add TaskStatus.isTerminal and TaskStatus.isActive.
Fix four unresolved dartdoc references and the TaskStatus state diagram (due retries move straight to running).
Add issue_tracker and topics to the pubspec.
No storage contract changes: existing QueueStorage adapters keep working.
The storage contract for adapter authors now lives in STORAGE.md at the package root.

0.1.0 #

Initial release of the durable task queue.
Serializable tasks with immutable payload snapshots and isolated execution attempts.
Indexed in-memory storage, bounded worker queries, and a documented storage contract.
Constant-delay and exponential retries, jitter, retry predicates, and attempt limits.
Concurrency limits, deduplication, idempotency metadata, and cancellation.
Pause, resume, and stop controls.
Lifecycle events, task queries, and failure metadata.
Batched startup recovery for interrupted tasks.
Automatic retries of worker storage operations without rerunning handlers, with a storage error stream and configurable retry delay.
An injectable clock so retry tests do not wait on real time.
