driving_conditions 0.5.5

Turn weather data into driving safety guidance. Road surface classification, grip estimation, visibility degradation, and Monte Carlo safety scoring. Pure Dart, no Flutter dependency.

0.5.5

Widens the navigation_safety_core constraint to >=0.10.0 <0.12.0.

The previous ^0.10.0 constraint excluded core 0.11.x, so a project that asked for the current core could not also take this package at its current version. The resolver silently selected an older release of this package instead, with no error and no warning. Core 0.11.0 and 0.11.1 are additive (a re-export, and a percent-to-fraction humidity factory); this package compiles and its full test suite passes against 0.11.1.

Also removes a dependency_overrides block that referenced sibling packages by relative path. It was inert for consumers, but it prevented this package from resolving standalone from its published archive.

No API or behaviour change.

Changelog

0.5.4

• deps: allow fleet_hazard: ^0.4.0 → ^0.5.0 (the anonymized-HazardZone dignity fix). driving_conditions consumes only the FleetReport input atom and the RoadCondition enum via FleetHazardConfidenceAdapter — neither changed in fleet_hazard 0.5.0 (only the retained HazardZone.reports type was anonymized from List<FleetReport> to List<ZoneObservation>, which this package never reads). Source-compatible; no lib/ code change. Unblocks integrators that pull both packages from pub.dev.

0.5.3

• Docs: de-promote the optional native (C FFI) NativeSafetyScoreSimulationEngine. The README now states the pure-Dart CpuSafetyScoreSimulationEngine is the default, and that the native path requires compiling the C library (native/build/lib...) first — it throws (DynamicLibrary.open / UnsupportedError) otherwise, with no silent fallback. Updated the README install snippet pin to ^0.5.3. No code change.

0.5.2

• 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.

0.5.1 — 2026-05-10 — Refresh cascade-stale dependency constraints

• driving_weather: ^0.3.0 → ^0.4.0 (consumer-side refresh after driving_weather 0.4.0 release earlier the same day).
• fleet_hazard: ^0.3.0 → ^0.4.0.
• No source changes; pubspec dep-constraint refresh only.

0.5.0

• Dep modernization (republish cascade): bump navigation_safety_core: ^0.1.0 → ^0.10.0 (closes 9-version stale dep) + snow_rendering: ^0.1.0 → ^0.2.0 (closes 1-version stale dep). NSC dep update consumes additive surface only (no breaking changes per NSC CHANGELOG 0.2.0–0.10.0). Closes 2-month publish-debt (pub.dev last at 0.3.0 from 2026-03-15).
• New: FleetConfidenceProvider abstract interface — pluggable fleet confidence for safety simulation.
• New: ConstantFleetConfidenceProvider — explicit named replacement for the 0.8 literal.
• New: FleetHazardConfidenceAdapter — derives confidence from List<FleetReport> using road condition safety factors (dry 1.0, wet 0.7, snowy 0.4, icy 0.1).
• CpuSafetyScoreSimulationEngine, NativeSafetyScoreSimulationEngine, and SafetyScoreSimulator now accept an optional FleetConfidenceProvider. Default behaviour is unchanged (0.8 constant).
• Native simulation_run_batch C function now accepts fleet_confidence as a parameter. Shared library rebuilt.
• Adds fleet_hazard: ^0.3.0 as a dependency.

0.4.0

• Refactor: drop direct navigation_safety package dependency; consume navigation_safety_core (pure-Dart core) only. Tracks the NSC pure-Dart core extraction (commit 86632c4); driving_conditions only uses the core safety vocabulary types and never required the Flutter+BLoC surface.
• Breaking: SafetyScoreSimulator.simulate() and SafetyScoreSimulationEngine.simulate() now return SimulationResult instead of SafetyScore.
• New type: SimulationResult — wraps the mean SafetyScore with statistical measures: variance, incidentCount, and (native engine only) executionMs.
• Promoted: NativeSafetyScoreSimulationEngine is now part of the public API. Edge developers can instantiate it directly to access native-engine execution timing.
• CpuSafetyScoreSimulationEngine.simulate() now computes and exposes variance and incidentCount from the Monte Carlo runs.

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.
