is3DPoint method

bool is3DPoint()

Checks if this point is a 3D point.

Example:

var point2D = Point(3, 4);
print(point2D.is3DPoint()); // Output: false

var point3D = Point(3, 4, 5);
print(point3D.is3DPoint()); // Output: true

Returns true if this point is 3D (i.e., z is not null), and false otherwise.

Implementation

bool is3DPoint() => z != null;
