h3_dart 0.5.0-dev.1

The package provides Dart version of the H3 Core library, a hexagon-based geographic grid system

0.5.0

• Split h3_flutter library into 2 libraries - h3_flutter and h3_dart for pure-dart projects.
• [BREAKING] remove h3 and geojson2H3 singletones.
  To access h3 you should use H3Factory().load() if you use h3_flutter and H3Factory().byPath(...) or H3Factory().byDynamicLibary(...) if you use h3_dart
• Add GeoCoordRadians to allow to specify coordinates in radians.
  GeoCoordRadians must be converted to GeoCoord using .toDegrees(converter) method before you can use it in h3 or geojson2h3 methods.
• Add option to convert GeoCoord to GeoCoordRadians via .toRadians(converter) method
• Add AngleConverter and GeoCoordConverter classes to convert between radians and degrees.
  AngleConverter is abstract, but has two implementations - H3AngleConverter and NativeAngleConverter

0.4.2

• Fix CoordIJ.toString() output
• Change CoordIJ.hashCodeto generate more unique hashcode
• Fix GeoCoord.toString() output
• Change GeoCoord.hashCodeto generate more unique hashcode
• Add world-wrapping feature to GeoCoord() constructor
• geojson2h3.h3ToFeature and geojson2h3.h3SetToFeatureCollection now adds 'properties': {} to output when properties not set. To make the behaviour closer to JS version of the library
• Change type for properties parameter in geojson2h3.h3SetToFeatureCollection function. Now it accepts Function() instead of Map
• Rename h3_flutter_test.dart to h3_test.dart
• Add tests for following methods:

geojson2h3.h3ToFeature
geojson2h3.h3SetToFeatureCollection
CoordIJ.==
CoordIJ.hashCode
CoordIJ.toString
GeoCoord.==
GeoCoord.hashCode
GeoCoord.toString
GeoCoord() (World-Wrapping)
H3Exception.toString

0.4.1

• Fix h3.getH3UnidirectionalEdgesFromHexagon method - now it returns 5 elements for pentagon.
• Fix h3.h3Line method - now it throws H3Exception instead of some internal when input is not valid.
• Update README.md.
• Update documentation for methods h3.h3ToParent, h3.h3ToCenterChild, h3.getH3UnidirectionalEdge, h3.getOriginH3IndexFromUnidirectionalEdge, h3.getDestinationH3IndexFromUnidirectionalEdge, h3.h3Distance.

h3.h3IndexesAreNeighbors
h3.getH3UnidirectionalEdge
h3.getOriginH3IndexFromUnidirectionalEdge
h3.getDestinationH3IndexFromUnidirectionalEdge
h3.h3UnidirectionalEdgeIsValid

0.4.0
