Flutter插件yesid_flutter的介绍与使用_yesid_flutter提供了多种功能，包括OCR识别、人脸注册、人脸认证和无接触指纹扫描等

在本文中，我们将探索如何在Flutter项目中使用yesid_flutter插件。该插件提供了多种功能，包括OCR识别、人脸注册、人脸认证和无接触指纹扫描等。

Getting Started

首先，将yesid_flutter插件添加到您的pubspec.yaml文件中：

dependencies:
  yesid_flutter: ^0.2.6-beta

然后运行以下命令以获取依赖项：

flutter pub get

Usage

导入插件并初始化

在您的Flutter项目中导入yesid_flutter插件，并初始化插件实例：

import 'package:yesid_flutter/yesid_flutter.dart';

final _yesidFlutterPlugin = YesidFlutter();

dynamic results;

[@override](/user/override)
Widget build(BuildContext context) {
  return Scaffold(
    appBar: AppBar(
      title: const Text("Yesid SDK"),
    ),
    body: Center(
      child: Column(
        children: [
          // 您的其他小部件
        ],
      ),
    ),
  );
}

功能示例

1. OCR 功能调用

通过摄像头进行OCR识别：

Future<dynamic> startOCRCamera() async {
    // 配置OCR参数
    final configuration = OCRConfigurationBuilder()
        .setAndroidLicense("ANDROID_LICENSE") // 设置Android许可证
        .setIOSLicense("IOS_LICENSE")         // 设置iOS许可证
        .setLensFacing(1)                     // 设置镜头方向（1为后置）
        .build();

    dynamic ocrResults;
    try {
      // 启动OCR相机
      ocrResults = await _yesidFlutterPlugin.startOCRCamera(configuration);
    } on PlatformException {
      // 异常处理
      ocrResults = 'Failed to get platform version.';
    }
    setState(() {
      results = ocrResults;
    });
}

2. 人脸注册

通过摄像头进行人脸注册：

Future<dynamic> startFaceEnrollment() async {
    // 配置人脸注册参数
    final configuration = FaceEnrollmentConfigurationBuilder()
        .setAndroidLicense("ANDROID_LICENSE") // 设置Android许可证
        .setIOSLicense("IOS_LICENSE")         // 设置iOS许可证
        .build();

    dynamic faceEnrollResults;
    try {
      // 启动人脸注册
      faceEnrollResults =
          await _yesidFlutterPlugin.startFaceEnrollment(configuration);
    } on PlatformException {
      // 异常处理
      faceEnrollResults = 'Failed to get faceEnrollment';
    }
    setState(() {
      results = faceEnrollResults;
    });
}

3. 人脸认证

通过两张图片进行人脸认证：

Future<dynamic> startFaceAuth() async {
    // 配置人脸认证参数
    final configuration = FaceAuthConfigurationBuilder()
        .setAndroidLicense("ANDROID_LICENSE") // 设置Android许可证
        .setIOSLicense("IOS_LICENSE")         // 设置iOS许可证
        .setFirstImage("base64image")         // 第一张图片（Base64编码）
        .setSecondImage("base64image")        // 第二张图片（Base64编码）
        .build();

    dynamic faceAuthResults;
    try {
      // 启动人脸认证
      faceAuthResults = await _yesidFlutterPlugin.startFaceAuth(configuration);
    } on PlatformException {
      // 异常处理
      faceAuthResults = 'Failed to get face auth';
    }
    setState(() {
      results = faceAuthResults;
    });
}

4. 无接触指纹扫描

通过配置无接触指纹扫描功能：

Future<dynamic> startTouchless() async {
    // 配置无接触指纹扫描参数
    final configuration = TouchlessConfigurationBuilder()
        .setAndroidLicense("ANDROID_LICENSE")       // 设置Android许可证
        .setIOSLicense("IOS_LICENSE")               // 设置iOS许可证
        .setFingerScanDirection(FingerScanDirections.THUMB_RIGHT) // 设置指纹扫描方向
        .build();

    dynamic touchlessResults;
    try {
      // 启动无接触指纹扫描
      touchlessResults =
          await _yesidFlutterPlugin.startTouchless(configuration);
    } on PlatformException {
      // 异常处理
      touchlessResults = 'Failed to start touchless: $touchlessResults';
    }
    setState(() {
      results = touchlessResults;
    });
}
