runtimeType → Type

A representation of the runtime type of the object.

Methods

distance(Point from, Point to) → double?

Computes the 2D distance between from and to positions. This implementation ignores all Point.altitude values. from and to must have geometry-based coordinates; if this is not the case, the function returns null. See also DistanceCalculator3D.

override

measure(Shape shape) → double?

Computes the 2D length of a line string or polygon. null is returned iif any Point in the lines or polygon is not geometry-based.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.
