isEmptyByGeometry property
Returns true if this geometry is considered empty.
Emptiness in the context of this classes extending Geometry is defined:
Point
has x and y coordinates with valuedouble.nan
.LineString
has an empty chain of points.Polygon
has an empty list of linear rings.MultiPoint
has no points.MultiLineString
has no line strings.MultiPolygon
has no polygons.GeometryCollection
has no geometries.
The specification from Bounded: "Returns true if this bounded object is considered empty (that is it do not contain any geometry directly or on child objects, or geometry contained is empty)".
Implementation
@override
bool get isEmptyByGeometry => _geometries.isEmpty;
