getMinZoomLevel(int cameraId) → Future<double>: Gets the minimum supported zoom level for the selected camera.
handleCameraMethodCall(MethodCall call, int cameraId) → Future: Converts messages received from the native platform into camera events.
initializeCamera(int cameraId, {ImageFormatGroup imageFormatGroup = ImageFormatGroup.unknown}) → Future<void>: Initializes the camera on the device.
lockCaptureOrientation(int cameraId, DeviceOrientation orientation) → Future<void>: Locks the capture orientation.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
onCameraClosing(int cameraId) → Stream<CameraClosingEvent>: The camera started to close.
onCameraError(int cameraId) → Stream<CameraErrorEvent>: The camera experienced an error.
onCameraInitialized(int cameraId) → Stream<CameraInitializedEvent>: The camera has been initialized.
onCameraResolutionChanged(int cameraId) → Stream<CameraResolutionChangedEvent>: The camera's resolution has changed. On Web this returns an empty stream.
onDeviceOrientationChanged() → Stream<DeviceOrientationChangedEvent>: The ui orientation changed.
