Flutter二维码扫描与识别插件qoreidsdk的使用

Flutter二维码扫描与识别插件qoreidsdk的使用

qoreidsdk 是一个用于 Flutter 应用的二维码扫描与识别插件。要使用该插件，您可以参考以下步骤进行安装和配置。

安装

首先，在您的 pubspec.yaml 文件中添加 qoreidsdk 依赖项：

dependencies:
  qoreidsdk: ^版本号

然后运行 flutter pub get 来获取该依赖项。

配置

具体配置步骤可以参考官方文档。通常情况下，您需要在 Android 和 iOS 平台上进行一些额外的配置。

使用示例

以下是一个完整的示例代码，展示了如何在 Flutter 应用中使用 qoreidsdk 插件进行二维码扫描和识别。

示例代码

import 'package:flutter/material.dart';
import 'package:qoreidsdk/qoreidsdk.dart';

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

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  [@override](/user/override)
  void initState() {
    super.initState();
    _initQoreidResults();
  }

  void _initQoreidResults() {
    Qoreidsdk.onResult((data) async {
      print(data);
      if (data["data"] != null) {
        print(data["data"]["verification"]["id"]);
      }
    });
  }

  void _launchQoreid(QoreidData data) async {
    await Qoreidsdk.launchQoreid(data);
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(home: MyForm(_launchQoreid));
  }
}

class MyForm extends StatefulWidget {
  final Function(QoreidData data) onSubmit;

  const MyForm(this.onSubmit, {super.key});

  [@override](/user/override)
  _MyFormState createState() => _MyFormState();
}

class _MyFormState extends State<MyForm> {
  final GlobalKey<FormState> _formKey = GlobalKey<FormState>();
