# 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();

## Properties

hashCode → int
  The hash code for this object.
  no setter inherited
hasListeners → bool
  Whether any listeners are currently registered.
  no setter inherited
isInitialized → bool
  Gets the current camera initialization status.
  no setter
isPaused → bool
  Gets the current pause status.
  no setter
runtimeType → Type
  A representation of the runtime type of the object.
  no setter inherited

## 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.
  inherited

## Operators

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