Constructors

FlMlKitScanning({Key? key, List<BarcodeFormat>? barcodeFormats, EventBarcodeListen? onDataChanged, Widget? overlay, ValueChanged<FlashState>? onFlashChanged, bool autoScanning = true, ValueChanged<CameraZoomState>? onZoomChanged, bool updateReset = false, CameraInfo? camera, CameraResolution resolution = CameraResolution.medium, BoxFit fit = BoxFit.fitWidth, Widget? uninitialized, double frequency = 500})

Properties

autoScanning → bool
是否自动扫描 默认为true Auto scan defaults to true
final
barcodeFormats → List<BarcodeFormat>
码识别类型 Identification type
final
camera → CameraInfo?
需要预览的相机 Camera ID to preview
final
fit → BoxFit
How a camera box should be inscribed into another box.
final
frequency → double
如果你设置为10, 2次解析数据间隔为10 毫秒，数字越小 在ios上cpu占有率越高，数字越大，识别速度会变慢，建议设置500-1500 If you set it to 10, The interval between data parsing is 10 milliseconds The larger the number, the slower the parsing,If the number is too small, the CPU percentage will be too high on ios Therefore, the recommended setting range is 500 to 1500
final
hashCode → int
