BaseMixinFeatureCameraV2 mixin

BaseMixinFeatureCameraV2 is a mixin class designed to facilitate camera-related functionalities. It provides methods for handling essential camera features, such as initializing the camera, taking pictures, switching between cameras, setting flash modes, starting and stopping image streams, and more.

This mixin can be used in widgets or classes where camera functionality is required, allowing for streamlined integration of camera operations in Flutter applications.

flashModeState ↔ FlashMode
The current flash mode of the camera (on, off, auto, etc.).
getter/setter pair

isStreamingImage → bool
no setter
resolutionPreset → ResolutionPreset

Methods

addListener({void onFlashModeChanged(FlashMode mode)?}) → void
Registers event listeners for camera features.
disposeCamera() → Future<void>
Disposes the active camera and resets flash mode to off.
initializeCamera({required CameraLensDirection cameraLensDirection, required void onCameraInitialized(CameraController controller), required void onCameraInitializedFailure(FeatureCameraException exception), ResolutionPreset resolutionPreset = ResolutionPreset.high, bool enableAudio = true, ImageFormatGroup? imageFormatGroup}) → Future<void>
Initializes the camera with the specified CameraLensDirection and handles success or failure callbacks.
initializeStreamingCamera({required CameraLensDirection cameraLensDirection, required void onCameraInitialized(CameraController controller), required void onCameraInitializedFailure(FeatureCameraException exception), ResolutionPreset resolutionPreset = ResolutionPreset.low, ImageFormatGroup? imageFormatGroup}) → Future<void>
Initializes the streaming camera, usually use for liveness detection.
isCameraAvailable(CameraLensDirection cameraLensDirection) → Future<bool>
Checks if a camera with the specified cameraLensDirection is available.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
resumeCamera({required void onCameraInitialized(CameraController controller), required void onCameraInitializedFailure(FeatureCameraException exception)}) → Future<void>
Resumes the camera with the last-used CameraLensDirection and initializes it.
setFlashMode(FlashMode flashMode) → Future<void>
Sets the camera's flash mode to the specified flashMode (off, on, auto, etc.).
startImageStream({required void onImageStream(CameraImage image, int sensorOrientation, DeviceOrientation deviceOrientation, CameraLensDirection cameraLensDirection)}) → Future<void>
Starts streaming the camera image data and triggers onImageStream every two seconds.
stopImageStream() → Future<void>
Stops the image stream from the camera.
switchCamera(CameraLensDirection cameraLensDirection) → Future<void>
Switches the active camera to the specified CameraLensDirection (front or rear).
takePicture({bool includeExif = false}) → Future<CaptureImageModel>
Captures a picture using the active camera and returns the file. If the camera controller is not initialized, this function will throw an error
toString() → String
A string representation of this object.

The equality operator.
