h3_core 1.0.6

Dart/Flutter bindings for Uber's H3 hexagonal geospatial indexing library. Uses dart:ffi on native platforms and h3-js on web — same API everywhere.

1.0.6

• Move repository to the wayqteam GitHub organization; refresh pubspec.yaml URLs (repository, homepage, issue_tracker) and README CI badge
• Bump dependencies to latest majors: hooks ^2.0.0, code_assets ^1.1.0, native_toolchain_c ^0.19.0, lints ^6.1.0
• Upgrade vendored H3 C library from 4.4.1 → 4.5.0 (upstream notes)
• Add reverseDirectedEdge — returns a directed edge with origin and destination swapped (FFI + stub; throws UnsupportedError on web pending h3-js 4.5)
• gridPathCells is now bidirectional: gridPathCells(a, b) reversed equals gridPathCells(b, a) (H3 v4.5.0 behavior change)
• cellsToLinkedMultiPolygon / cellsToMultiPolygon now surface E_CELL_INVALID, E_RES_MISMATCH, and E_DOMAIN for invalid input, mixed resolutions, and duplicate cells (previously undefined output)
• Internal: refactored indexing (now uses Vec3d) and CoordIJK (now inlineable) from upstream — transparent to callers
• Regenerate FFI bindings against H3 v4.5.0 headers
• Refresh README badges and version references
• Expand pub.dev metadata: add homepage, issue_tracker, documentation, refined topics for better discoverability

1.0.5

1.0.4

• Switch h3-js CDN from jsDelivr to unpkg

1.0.3

• Update README with badges and structured platform support documentation

1.0.2

• Fix Windows build: add BUILD_SHARED_LIBS and BUILDING_H3 defines for DLL symbol export
• Fix Windows build: skip libm linking (math is part of the C runtime on Windows)
• Remove deprecated avoid_returning_null_for_future lint rule
• Add CI/CD: automated testing on Linux, macOS, Windows, and Chrome
• Add automated publishing to pub.dev via GitHub Actions OIDC

1.0.1

• Web support via h3-js and dart:js_interop
• H3Index changed from int-backed to String-backed to avoid JS number precision loss
• Same public API on all platforms (conditional export: FFI on native, h3-js on web)
• getIndexDigit / constructCell use BigInt on web for 64-bit precision

1.0.0

• Initial release wrapping H3 v4.4.1
• Full H3 API: indexing, inspection, traversal, hierarchy, edges, vertices, measurements, regions, coordinates
• Native compilation via Build Hooks for Android, iOS, macOS, Linux, Windows
• Auto-generated FFI bindings via ffigen 20.x
• Async wrappers for heavy operations (polygonToCells, gridDisk, compact/uncompact)
