Point class

A point with x, y, and optional z coordinates.

Used to represent landmarks with optional depth information. The x and y coordinates are in absolute pixel positions relative to the original image. The z coordinate represents relative depth (scale-dependent) when 3D computation is enabled.

When z is null, this represents a 2D point. When z is non-null, it represents a 3D point with depth information.

Constructors

Point(double x, double y, [double? z])

Creates a point with the given x, y, and optional z coordinates.

const

Point.fromMap(Map<String, dynamic> map)

Creates a point from a map (isolate deserialization).
