HandLandmarkFrame class

A single frame of 21 hand landmarks produced by an on-device ML source (MediaPipe Hand Landmarker, ML Kit, or any compatible detector).

The engine is source-agnostic: the host app owns the camera and the ML model (e.g. google_mlkit_vision, a MediaPipe Tasks platform channel, or WebRTC in-browser tracking) and feeds normalized frames here.

Constructors

HandLandmarkFrame({required List<Vector3> landmarks, required ControllerHand hand, double confidence = 1.0, DateTime? timestamp})

Properties

confidence → double

Detection confidence in 0..1.

final

hand → ControllerHand

Which hand this frame belongs to.

final

hashCode → int

The hash code for this object.

no setter, inherited

landmarks → List<Vector3>

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

timestamp → DateTime

Capture time of the frame.
