any_map

New features

• Reactive streams — cameraPositionStream and visibleBoundsStream on AnyMapController for live camera updates
• User location layer — AnyUserLocationLayer widget with pulsing accuracy ring, heading wedge, and blue dot
• Marker popup — AnyMarkerPopup widget that tracks camera movement and floats above any marker
• Animated polyline drawing — animatePolyline() progressively reveals a route over a configurable duration
• Bounds with insets — fitBoundsWithInsets() supports per-edge padding (top/right/bottom/left)
• GeoJSON improvements — AnyGeoJsonLayer.fromString() factory and fromAsset() async loader
• Tile caching — AnyCachingTileProvider with LRU in-memory cache, optional AnyTileStore for durable storage, TTL expiry, and hit/miss stats
• Snapshot / screenshot — takeSnapshot() returns a dart:ui Image of the current map view
• Error handling — AnyMapError typed errors with AnyMapErrorType enum; onError callback on AnyMapWidget
• Fake adapter for testing — AnyMapFakeAdapter and AnyMapFakeController record all calls for widget tests without a real map view
• Distance matrix — AnyDistanceMatrix computes travel time and distance for multiple origin→destination pairs via OSRM Table API (free, no API key)
• Map matching / GPS snapping — AnyMapMatcher snaps noisy GPS traces to the road network via OSRM Match API
• Route optimization — AnyRouteOptimizer solves multi-stop TSP via OSRM Trip API and returns the optimal stop order
• Nearby POI search — AnyPlaces.search() queries Overpass API for restaurants, hospitals, ATMs, parks, and more (free, no API key)
• Photon geocoding provider — PhotonSearchProvider backed by Komoot's free public Photon server (no API key, self-hostable)
• Pelias geocoding provider — PeliasSearchProvider for self-hosted Pelias instances (free and open-source)
• OpenCage geocoding provider — OpenCageSearchProvider with 2,500 requests/day free tier
• Places search field widget — AnyPlacesSearchField drop-in search bar with debounce, loading indicator, overlay dropdown, clear button, and custom item builder

Breaking changes

• AnyMapController now declares five new abstract members that all adapters must implement: cameraPositionStream, visibleBoundsStream, fitBoundsWithInsets(), animatePolyline(), takeSnapshot()

Testing

• 85 unit tests covering AnyLatLng, AnyLatLngBounds, PolylineCodec, AnyClusterEngine, AnyMatrixCell, AnyOptimizedRoute, AnyMapMatchResult, AnyRoute, AnySpeedLimit, AnyFuelConfig, AnyTripLogger, AnyTripSummary, AnyGeofence, AnyGeofenceEngine, AnyCachingTileProvider, AnyGeoJsonLayer, and AnyCacheStats
