offline_tiles 0.5.1

MBTiles-backed offline tile management for flutter_map. Pre-cache routes / regions; resolve tiles locally when offline.

Changelog

0.5.1 — 2026-05-10 — Pana score recovery (Theme α P4)

• Trim pubspec description to within the pana 60–180 character target.
• Apply dart format to clear any formatter findings.
• No SDK source changes; metadata + format pass only.

0.5.0

• Add PerformanceBudget — stateful frame-timing budget tracker for tile-render advisory cognitive-load management. Integrator-supplied FrameTimingProvider interface; per-frame budget checked against PerformanceBudgetConfig; broadcast budgetEvents stream emits BudgetWarning (75% sustained) / BudgetExhausted (100% sustained over sustainedFrames consecutive frames). Mirrors the GlanceBudgetTracker pattern from navigation_safety 0.9.0 (caution-add-only / severity-not-profile / driver-always-drives invariants enforced via debug-mode runtime asserts).
• Add PerformanceBudgetConfig.forProfile(DriverProfile) factory — per- cohort lenient-direction defaults (16ms baseline / 18ms noviceUrban / 22ms ageingRural + foreignTouristSnowZone for visual-cognitive-margin). Per-cohort budgets are UNVERIFIED-magnitude design-default-hypothesis pending field- measurement validation; conservative-only (every cohort >= 16ms baseline). Per-population calibration deferred.
• Add BudgetResetReason enum — render-cycle / long-pause / explicit.
• Add navigation_safety_core: ^0.10.0 dependency for DriverProfile consumption. Add equatable: ^2.0.7 (used by sealed event classes).
• Add SAFETY_BOUNDARY.md (driving-automation-regime declaration; PerformanceBudget invariants; ASIL-QM advisory; severity-not-profile
  • driver-always-drives preserved).
• Add KNOWN_LIMITATIONS.md (per-cohort budget UNVERIFIED-magnitude flags + integrator-side FrameTimingProvider supply-chain caveats).
• Public API additions are non-breaking; existing OfflineTileManager / providers / resolvers contracts unchanged.

0.4.0

• Migrate to mbtiles ^0.5.0 and sqlite3 ^3.2.0 (native assets).
• Remove EOL sqflite dependency.
• Remove unused flutter_map_mbtiles phantom dependency.
• Internal API update: MbTiles(path:), MbTiles.create(path:), close() replacing dispose().
• Public API unchanged: OfflineTileManager(mbtilesPath:) contract preserved.

0.3.0

• Harmonize package version to 0.3.0 for Sprint 80 Direction F.
• Align internal ecosystem dependency constraints to ^0.3.0 where applicable.
• No breaking API changes in this package for this release.
