Constructors
- CameraValue({required bool isInitialized, String? errorDescription, Size? previewSize, required bool isRecordingVideo, required bool isTakingPicture, required bool isStreamingImages, required bool isRecordingPaused, required FlashMode flashMode, required ExposureMode exposureMode, required FocusMode focusMode, required bool exposurePointSupported, required bool focusPointSupported, required DeviceOrientation deviceOrientation, required CameraDescription description, DeviceOrientation? lockedCaptureOrientation, DeviceOrientation? recordingOrientation, bool isPreviewPaused = false, DeviceOrientation? previewPauseOrientation})
-
Creates a new camera controller state.
const
- CameraValue.uninitialized(CameraDescription description)
-
Creates a new camera controller state for an uninitialized controller.
