map_viewport_bloc 0.4.2

Declarative camera state machine (follow / free look / route overview) for navigation maps with six-layer composition.

Changelog

0.4.2

• Republish from the embedded-target Dart 3.10.1 SDK (Flutter 3.38.3) to correct a stale ^3.11.0 SDK floor in the previously-published artifact. No source or behavior change; the source already declared sdk: ^3.10.0. Restores pub get for embedded/automotive Dart consumers on Dart 3.10.x.

0.4.1 — 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.

0.4.0

• Add ViewportRenderBudgetBloc — composes PerformanceBudget (from offline_tiles 0.5.0) and DataBudget (from snow_rendering 0.2.0) streams into a single ViewportRenderState with a RenderFidelity recommendation (high / medium / low).
• Caution-add-direction-wins on conflict (load-bearing): any BudgetExhausted on either stream → fidelity LOW; otherwise any BudgetWarning → fidelity MEDIUM; else HIGH. The bloc never RAISES fidelity in response to a stream event; reset returns to HIGH.
• Add ViewportRenderConfig.forProfile(DriverProfile) factory with per-cohort RenderFidelityFloor (UNVERIFIED-magnitude design- default-hypothesis). Cohorts ageingRural / foreignTouristSnowZone / noviceUrban get MEDIUM floor (bloc never drops to LOW; visual-cognitive-margin demands richer rendering). Cohorts professional / snowZoneExperienced / agriculturalForestry get LOW floor.
• Add attachPerformanceBudgetStream / attachDataBudgetStream — runtime-typed listener subscription.
• Add ViewportBudgetReset event — integrator-driven; returns fidelity to HIGH and clears observed-flags.
• Add navigation_safety_core: ^0.10.0 dependency for DriverProfile consumption.
• Add SAFETY_BOUNDARY.md (viewport-class composition invariants; caution-add-direction-wins on conflict; ASIL-QM advisory; severity-not-profile + driver-always-drives preserved).
• Add KNOWN_LIMITATIONS.md (viewport-class composition strategy UNVERIFIED-magnitude; per-cohort RenderFidelityFloor design- default-hypothesis).
• Public API additions are non-breaking; existing MapBloc / MapState / MapEvent / model contracts unchanged.

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.
