fl_mlkit_scanning
githut地址 pub地址 基于Google ML Kit实现快速稳定扫码功能，支持Android\IOS Realize fast and stable code scanning function based on Google ML Kit, and support Android \ IOS 相机相关功能依赖于 fl_camera Camera related functions depend on fl_camera 使用 use ios 添加相机权限 Add camera permissions to IOS NSCameraUsageDescription 是否允许FlMlKitScanning使用你的相机？ 预览 preview Widget build(BuildContext context) { return FlMlKitScanning( /// 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500-100 /// 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 1000 frequency: 500, /// 需要预览的相机 不传值 默认为后摄像头 /// Camera ID to preview camera: camera, /// 预览相机支持的分辨率 /// Preview the resolution supported by the camera resolution: CameraResolution.high, /// 是否自动扫描 默认为[true] /// Auto scan defaults to [true] autoScanning: false, /// 显示在预览上层 /// Display above preview box overlay: const ScannerLine(), /// 更新组件时是否重置相机 /// Reset camera when updating components updateReset: false, /// 相机预览位置 /// How a camera box should be inscribed into another box. fit: BoxFit.fitWidth, /// 闪光灯状态 /// Flash status onFlashChanged: (FlashState state) { showToast('$state'); }, /// 缩放变化 /// zoom ratio onFlashChanged: (FlashState state) { showToast('$state'); }, /// 相机在未初始化时显示的UI /// The UI displayed when the camera is not initialized uninitialized: Container( color: Colors.black, alignment: Alignment.center, child: const Text( 'Camera not initialized', style: TextStyle(color: Colors.white))), /// 二维码识别类型 默认仅识别qr_code，需要识别几种就添加几种 /// Identification type Only QRcode is recognized by default barcodeFormats: [BarcodeFormat.qr_code], /// 扫码回调 /// Code scanning callback onDataChanged: (AnalysisImageModel data) { final List? barcodes = data.barcodes; if (barcodes != null && barcodes.isNotEmpty) { /// 返回数组 可识别多个码 /// Return array } }); } 方法 method void func() { /// 设置设别码类型 /// Set type controller.setBarcodeFormat(); /// 识别图片字节 /// Identify picture bytes controller.scanImageByte(); /// 打开\关闭 闪光灯 /// Turn flash on / off controller.setFlashMode(); /// 相机缩放 /// Camera zoom controller.setZoomRatio(); /// 暂停扫描 /// Pause scanning controller.pause(); /// 开始扫描 /// Start scanncing controller.start(); } |
