steady_async 0.3.1

Flutter widgets and controllers for async loading, retries, actions, and pagination.

0.3.1

• Made finite streams leave loading when they complete without a new value.
• Paused obsolete stream subscriptions before replacement and reported asynchronous cancellation failures through Flutter diagnostics.
• Moved paged sliver auto-loading into a mounted widget lifecycle.
• Added release-mode validation for retry, timeout, transition, progress, and pagination prefetch configuration.
• Gated trusted publishing on format, analysis, tests, and a publish dry-run.
• Kept the PowerShell release verifier working around a Pana Windows sandbox regression.

0.3.0

• Added typed failure metadata, sanitized observer failure metadata, retry policies, per-operation timeouts, real cancellable-operation factories, UTC request timestamps, and staleness APIs.
• Added payload-free lifecycle observation for request, cancellation, source, and optimistic transaction events.
• Added application error mapping for default async, action, and pagination UI.
• Added seeded pagination hydration and atomic clear/retain source replacement.
• Added immediate insert/update and transactional optimistic insert/update/remove with refresh/append rebasing and stale-handle invalidation.
• Added optimistic action execution across drop, latest-wins, and sequential concurrency policies.
• Added SteadyPagedSliverGrid and item-threshold prefetch for paged slivers.
• Preserved raw error access and existing Future factories for 0.x migration.
• Made request start, cancellation, reset, source replacement, and disposal safe against synchronous callback and listener reentrancy.
• Preserved loader identity across retry attempts and retained successful attempt metadata.
• Made optimistic handles single-resolution transactions and ordered latest-wins rollback before replacement apply.
• Refreshed seeded slivers automatically and preserved initial-load retry metadata.

0.2.2

• Made request cancellation leave loading by restoring retained data or idle.
• Preserved the latest stream value when a later stream event fails.
• Made synchronous stream-factory failures rebuild through the guarded error path.
• Preserved appendError when omitted from paged-state copies while still clearing it with clearError.
• Made list, grid, and sliver pagination use the append-loading surface consistently for empty non-terminal pages.
• Applied updated success-visibility durations to owned action controllers.
• Made async-controller configuration and reset calls safe after disposal.

0.2.1

• Prevented sequential actions queued before disposal from executing afterward.
• Made keepPreviousData: false hide retained content as documented.
• Preserved the original loader-delay deadline across progress updates.
• Continued list and grid pagination when a page does not fill the viewport.
• Continued list, grid, and sliver pagination past empty non-terminal pages.
• Stopped list, grid, and sliver prefetch from retrying failed appends until the retry action is invoked.
• Kept refresh errors visible alongside retained items with retry support.
• Added a dedicated inline refreshErrorBuilder so existing full-screen errorBuilder implementations keep their original layout contract.
• Handled list scroll-controller and async-controller replacement correctly.
• Avoided auto-starting non-idle external controllers while preserving reloadOnLoaderChange during controller replacement.
• Detected repeated cursor cycles across a pagination session.

0.2.0

• Hardened paged-controller disposal, reset, refresh, and stale-result behavior.
• Added non-advancing cursor detection and controller-replacement loading.
• Added removeWhere and removeByKey with stale-result invalidation.
• Added custom loading and error builders for list, grid, and sliver pagination.

0.1.0

• Initial release with Future and Stream builders that manage loader timing.
• Added immutable async state, explicit controllers, actions, and pagination.
• Added Material 3 defaults, reduced-motion handling, and nine locales.
