LivenessCheckController class

Controller for managing liveness check camera operations.

This controller allows external control over camera initialization, disposal, and state management for the liveness check screen.

Example:

final controller = LivenessCheckController();

LivenessCheckScreen(
  controller: controller,
  config: LivenessCheckConfig(...),
)

// Later, manually control camera
controller.initializeCamera();
controller.disposeCamera();

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
override
disposeCamera() → Future<void>
Disposes the camera and releases all resources.
initializeCamera() → Future<void>
Initializes the camera for liveness detection.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
pauseDetection() → Future<void>
Pauses camera preview and face detection.
registerDisposeCallback(VoidCallback callback) → void
Internal method to register camera disposal callback. Called by LivenessCheckScreen only.
registerInitializeCallback(VoidCallback callback) → void
Internal method to register camera initialization callback. Called by LivenessCheckScreen only.
registerPauseCallback(Future<void> callback()) → void
Internal method to register pause detection callback. Called by LivenessCheckScreen only.
registerResetCallback(VoidCallback callback) → void
Internal method to register state reset callback. Called by LivenessCheckScreen only.
registerResumeCallback(Future<void> callback()) → void
Internal method to register resume detection callback. Called by LivenessCheckScreen only.
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
resetState() → void
Resets the liveness check state.
resumeDetection() → Future<void>
Resumes camera preview and face detection.
setInitialized(bool value) → void
Internal method to set initialization status. Called by LivenessCheckScreen only.
setPaused(bool value) → void
Internal method to set pause status. Called by LivenessCheckScreen only.
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
