Static Methods

decode(Uint8List bytes) → ReportShapeLayer

Reads encode.

parse(Uint8List bytes, {Uint8List? attributes, String? keyField, String? nameField}) → ReportShapeLayer

Shapefile (.shp), GeoJSON, or encode bytes. attributes is the .dbf beside a shapefile. keyField names the attribute used as ReportShapeFeature.key; without it a code or name column is chosen.

parseGeoJson(String text, {String? keyField, String? nameField}) → ReportShapeLayer

GeoJSON FeatureCollection, Feature, or Polygon.

parseShapefile(Uint8List shp, {Uint8List? attributes, String? keyField, String? nameField}) → ReportShapeLayer

ESRI polygon shapefile. attributes supplies the region key.

read(Uint8List bytes, {Uint8List? attributes, String? keyField, String? nameField}) → ReportShapeFile

Reads a shape file and names the attribute that became each region's key.
