Flutter欧洲驾照数据捕获插件scandit_flutter_datacapture_id_europe_driving_license的使用

Flutter欧洲驾照数据捕获插件scandit_flutter_datacapture_id_europe_driving_license的使用

scandit_flutter_datacapture_id_europe_driving_license 是一个库，用于解码欧洲驾照背面的信息。

示例代码

以下是一个简单的示例，展示如何在Flutter应用中使用 scandit_flutter_datacapture_id_europe_driving_license 插件来捕获欧洲驾照的数据。

import 'package:flutter/material.dart';
import 'package:scandit_flutter_datacapture_id/scandit_flutter_datacapture_id.dart';
import 'package:scandit_flutter_datacapture_id_europe_driving_license/scandit_flutter_datacapture_id_europe_driving_license.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('欧洲驾照数据捕获'),
        ),
        body: Center(
          child: DataCaptureView(
            dataCaptureViewfinder: BarcodePickerViewfinder(),
            dataCaptureController: _createDataCaptureController(),
          ),
        ),
      ),
    );
  }

  DataCaptureController _createDataCaptureController() {
    // 创建数据捕获上下文
    var context = DataCaptureContext.forLicenseKey("YOUR_SCANDIT_LICENSE_KEY");

    // 初始化ID数据捕捉模式
    var idDataCaptureMode = IdDataCaptureMode();
    context.addMode(idDataCaptureMode);

    // 添加欧洲驾照识别能力
    var europeDrivingLicenseCapability = EuropeDrivingLicenseRecognition();
    idDataCaptureMode.addCapability(europeDrivingLicenseCapability);

    // 创建条形码捕捉器
    var barcodeCapture = BarcodeCapture.forDataCaptureContext(context);
    context.addMode(barcodeCapture);

    // 创建数据捕捉控制器
    return DataCaptureController(context, [barcodeCapture]);
  }
}

步骤说明

  1. 导入必要的包:

    import 'package:flutter/material.dart';
import 'package:scandit_flutter_datacapture_id/scandit_flutter_datacapture_id.dart';
import 'package:scandit_flutter_datacapture_id_europe_driving_license/scandit_flutter_datacapture_id_europe_driving_license.dart';

  2. 创建数据捕获上下文:

    var context = DataCaptureContext.forLicenseKey("YOUR_SCANDIT_LICENSE_KEY");

    你需要将 "YOUR_SCANDIT_LICENSE_KEY" 替换为你的Scandit许可证密钥。

  3. 初始化ID数据捕捉模式:

    var idDataCaptureMode = IdDataCaptureMode();
context.addMode(idDataCaptureMode);

  4. 添加欧洲驾照识别能力:

    var europeDrivingLicenseCapability = EuropeDrivingLicenseRecognition();
idDataCaptureMode.addCapability(europeDrivingLicenseCapability);

  5. 创建条形码捕捉器:

    var barcodeCapture = BarcodeCapture.forDataCaptureContext(context);
context.addMode(barcodeCapture);

  6. 创建数据捕捉控制器:

    return DataCaptureController(context, [barcodeCapture]);

  7. 在UI中使用DataCaptureView组件:

    DataCaptureView(
  dataCaptureViewfinder: BarcodePickerViewfinder(),
  dataCaptureController: _createDataCaptureController(),
)

scandit_flutter_datacapture_id_europe_driving_license 是一个用于 Flutter 的插件，它允许你在应用中捕获和解析欧洲驾照的数据。这个插件基于 Scandit 的扫描技术，能够高效地读取驾照上的信息，并将其转换为结构化的数据。

安装插件

首先，你需要在 pubspec.yaml 文件中添加 scandit_flutter_datacapture_id_europe_driving_license 插件的依赖：

dependencies:
  flutter:
    sdk: flutter
  scandit_flutter_datacapture_id_europe_driving_license: ^x.x.x  # 请替换为最新版本

然后运行 flutter pub get 来安装插件。

配置 Scandit 许可证

在使用 Scandit 插件之前，你需要配置 Scandit 的许可证。你可以在 main.dart 文件中进行配置：

import 'package:scandit_flutter_datacapture_core/scandit_flutter_datacapture_core.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  // 配置 Scandit 许可证
  ScanditFlutterDataCaptureCore.configure('YOUR_SCANDIT_LICENSE_KEY');
  
  runApp(MyApp());
}

扫描欧洲驾照

接下来，你可以使用 scandit_flutter_datacapture_id_europe_driving_license 插件来扫描欧洲驾照并捕获数据。

import 'package:flutter/material.dart';
import 'package:scandit_flutter_datacapture_core/scandit_flutter_datacapture_core.dart';
import 'package:scandit_flutter_datacapture_id/scandit_flutter_datacapture_id.dart';
import 'package:scandit_flutter_datacapture_id_europe_driving_license/scandit_flutter_datacapture_id_europe_driving_license.dart';

class DLScanner extends StatefulWidget {
  [@override](/user/override)
  _DLScannerState createState() => _DLScannerState();
}

class _DLScannerState extends State<DLScanner> {
  DataCaptureContext? _dataCaptureContext;
  IdCapture? _idCapture;
  Camera? _camera;

  [@override](/user/override)
  void initState() {
    super.initState();
    _setupScanner();
  }

  void _setupScanner() async {
    // 创建 DataCaptureContext
    _dataCaptureContext = DataCaptureContext.forLicenseKey('YOUR_SCANDIT_LICENSE_KEY');

    // 设置相机
    _camera = Camera.defaultCamera;
    _dataCaptureContext!.setCamera(_camera);

    // 创建 IdCapture 模式
    _idCapture = IdCapture.forContext(_dataCaptureContext!, IdCaptureSettings());

    // 监听扫描结果
    _idCapture!.addListener(_onIdCaptured);

    // 启动相机
    _camera!.switchToDesiredState(FrameSourceState.on);
  }

  void _onIdCaptured(IdCapture capture, IdCaptureSession session, FrameData frameData) {
    final capturedId = session.newlyCapturedId;
    if (capturedId != null) {
      // 解析欧洲驾照数据
      final europeDrivingLicense = capturedId.europeDrivingLicense;
      if (europeDrivingLicense != null) {
        print('Name: ${europeDrivingLicense.firstName} ${europeDrivingLicense.lastName}');
        print('Date of Birth: ${europeDrivingLicense.dateOfBirth}');
        print('License Number: ${europeDrivingLicense.licenseNumber}');
        // 其他字段...
      }
    }
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('European Driving License Scanner'),
      ),
      body: Center(
        child: Text('Scanning...'),
      ),
    );
  }

  [@override](/user/override)
  void dispose() {
    _idCapture?.removeListener(_onIdCaptured);
    _dataCaptureContext?.dispose();
    super.dispose();
  }
}
