cluster_marker_style 0.3.0

cluster_marker_style: ^0.3.0 copied to clipboard

• Fix: drop shadows were clipped. ClusterShadow.extent reserved only blur + offset.distance of canvas margin, but a Gaussian blur stays visible out to roughly three sigma — so the soft edge of the shadow was cut off. The reach is now 3 * sigma + offset.distance, and the sigma conversion is exposed as ClusterShadow.sigma instead of being duplicated inside the renderer. Shadowed icons rasterize to a slightly larger bitmap; the shape stays centered, so marker anchoring is unchanged.
• Fix: flusterMarkers(...) built markers one at a time. Each cluster icon was awaited in sequence, so a viewport of N clusters serialized N rasterizations. Markers are now built concurrently via Future.wait and are still returned in the order the items were given.
• Fix: ClusterStyle.copyWith could not clear border or shadow. Passing null keeps the current value (that is what a missing copyWith argument means), which made "ClusterStyle.soft() without its shadow" impossible to express. Added removeBorder / removeShadow flags: ClusterStyle.soft().copyWith(removeShadow: true).
• Fix: ClusterIconCache was unbounded by default. It now caps at kDefaultClusterIconCacheSize (256) entries with LRU eviction, so a long session that keeps producing new visual outcomes (a changing device pixel ratio, a formatter that emits a unique label per count) can't grow it without bound. Use ClusterIconCache.unbounded() for the old behavior. A cache hit now also refreshes recency regardless of whether a cap is set.
• Tests: added coverage for the google_maps_cluster_manager_2 adapter, which previously had none, plus shadow geometry, the copyWith flags, cache eviction order, and fluster marker ordering.

• Add a fluster adapter (package:cluster_marker_style/cluster_marker_style_fluster.dart): flusterMarkers(...) and flusterClusterMarkers(...) turn Fluster.clusters(bbox, zoom) results into styled, cached map markers. fluster supplies only the clustering algorithm; this package renders the cluster icons.
• Cluster markers from both adapters are now center-anchored (Offset(0.5, 0.5)), so the bubble sits on the cluster location instead of above it.
• Example app gains a runnable fluster demo (flutter run -t lib/fluster_example.dart).

Initial release.

• ClusterStyle with value equality and three polished named styles (.soft, .flat, .outlined).
• CountTier count-aware color/size buckets and a logarithmic size curve.
• CountFormatter with a good-looking DefaultCountFormatter (e.g. 1500 -> "1.5k", optional "N+" cap).
• ClusterRenderer: device-correct PictureRecorder/Canvas/TextPainter pipeline that disposes its ui.Image and emits a BitmapDescriptor via imagePixelRatio.
• ClusterIconCache with visual-outcome cache keys, in-flight de-duplication, optional LRU eviction, and clear().
• One-line clusterMarkerBuilder(...) adapter for google_maps_cluster_manager_2, in a separate library so the core stays independent of it.
• Runnable example app with a live style switcher.
