+# SDScan
+
+#### 前言
+***
+
+flutter_dong_scan是一个可以定做UI的二维码扫描库.
+
+参考库如下所示。安卓部分是基于 zxing-android-embedded 这个库，iOS是参考 ZFScan 改造的。
+
+[Android部分：zxing-android-embedded](https://github.com/journeyapps/zxing-android-embedded)
+
+[iOS部分：ZFScan](https://github.com/Zirkfied/ZFScan)
+
+
+<br>
+
+#### 简单上手
+***
+
+首先我们在 **pubspec.yaml** 文件中导入下面内容。然后再执行 **flutter pub get** 命令。
+
+```
+
+dependencies:
+  flutter_dong_scan: ^最新版本
+
+```
+
+同时,我们需要把项目中build.gradle的minSdkVersion设置为19.
+
+```
+android {
+    ...
+    defaultConfig {
+        minSdkVersion 19
+        ...
+    }
+}
+```
+
+对于iOS部分，由于插件本身有图片资源，所以我们需要改动下我们的 **build System**。
+
+具体操作是 打开Xcode,从菜单栏中找到  **File → Workspace Settings** ,然后打开.
+
+然后我们需要把 **build System** 为 **Legacy Build System**。
+
+
+然后我们需要在Android的 **AndroidManifest.xml** 和 iOS 的 **info.plist** 添加权限请求， 具体如下所示。
+
+这里要说明一下iOS部分添加权限需要注意的问题，如果你的App想要上线AppStore,我建议你把 “该Demo想使用您的相机” 这句话改为更加详细的阐述，不然挨拒那是必然的。**UIViewControllerBasedStatusBarAppearance** 这个属性为什么要设置，这里我需要说明下，我为UI的统一把状态栏前景色改为白色，所以需要设置这个属性，可以不设置跟随整体主色走。
+
+###### Android 部分
+
+```
+<?xml version="1.0" encoding="utf-8"?>
+<manifest xmlns:android="http://schemas.android.com/apk/res/android">
+
+    <uses-permission android:name="android.permission.INTERNET" />
+    <uses-permission android:name="android.permission.VIBRATE" />
+    <uses-permission android:name="android.permission.FLASHLIGHT" />
+    <uses-permission android:name="android.permission.CAMERA" />
+
+    <application>
+        .....
+    </application>
+
+</manifest>
+```
+
+###### iOS部分
+
+```
+
+<?xml version="1.0" encoding="UTF-8"?>
+<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
+<plist version="1.0">
+<dict>
+	<key>NSCameraUsageDescription</key>
+	<string>该Demo想使用您的相机</string>
+	<key>UIViewControllerBasedStatusBarAppearance</key>
+	<false/>
+
+    ......
+
+</dict>
+</plist>
+
+```
+
+上面配置完成之后，我们导入SDScan,如下所示。
+
+```
+
+import 'package:flutter_dong_scan/scan.dart';
+
+```
+
+然后我们就可以如下进行调用了。
+
+```
+      ScanConfig scanConfig = ScanConfig();
+      SDScan scan = SDScan().setScanEventListener((dynamic codeString){
+          print("扫描结果:" + codeString);
+      });
+      scan.startScan(config: scanConfig);
+```

+
+## Getting Started
+
+This project is a starting point for a Flutter application.
+
+A few resources to get you started if this is your first Flutter project:
+
+- [Lab: Write your first Flutter app](https://flutter.dev/docs/get-started/codelab)
+- [Cookbook: Useful Flutter samples](https://flutter.dev/docs/cookbook)
+
+For help getting started with Flutter, view our
+[online documentation](https://flutter.dev/docs), which offers tutorials,
+samples, guidance on mobile development, and a full API reference.
