## 1.安装

使用当前包作为依赖库

### 1. 依赖此库

在文件 'pubspec.yaml' 中添加

```

dependencies:

ai_barcode: ^version

```

或者以下方式依赖

```
dependencies:

# barcode package.
  ai_barcode:
    git:
      url: https://github.com/pdliuw/ai_barcode.git

```

### 2. 安装此库

你可以通过下面的命令行来安装此库

```

$ flutter pub get

```

你也可以通过项目开发工具通过可视化操作来执行上述步骤

### 3. 导入此库

现在，在你的Dart编辑代码中，你可以使用：

```

import 'package:ai_barcode/ai_barcode.dart';

```

## 2.使用

使用'相机'需要动态申请权限，动态权限推荐：[permission_handler](https://github.com/Baseflow/flutter-permission-handler)

配置权限

Android权限配置:

```

<uses-permission android:name="android.permission.CAMERA"/>
    
```

iOS权限配置:

```

<key>NSCameraUsageDescription</key>
    <string>Can we access your camera in order to scan barcodes?</string>

```

iOS支持PlatformView配置：

```
	
    <key>io.flutter.embedded_views_preview</key>
    <true/>
    
```

### 1.使用'一维条码、二维条码'的地方中：

* 1、识别条码 简要示例

```
                //cameraWidth:相机的宽度;cameraHeight相机的高度,可根据实际的业务来动态调整
                Container(
                  color: Colors.black26,
                  width: cameraWidth,
                  height: cameraHeight,
                  child: PlatformAiBarcodeScannerWidget(
                    platformScannerController: _scannerController,
                  ),
                ),

```

* 2、生成/创建条码 简要示例

```
            Column(
              children: <Widget>[
                Text("生成的二维码：$_qrCodeOfInput"),
                Container(
                  width: 300,
                  height: 300,
                  decoration: ShapeDecoration(
                    shape: RoundedRectangleBorder(
                      side: BorderSide(
                        color: Colors.blue,
                        width: 15,
                      ),
                      borderRadius: BorderRadius.all(
                        Radius.circular(10),
                      ),
                    ),
                  ),
                  margin: EdgeInsets.all(40),
                  child: PlatformAiBarcodeCreatorWidget(
                    creatorController: _creatorController,
                    initialValue: "$_qrCodeOfInput",
                  ),
                ),
              ],
            ),

```

### 2.调用/应用

*1、打开相机设备

```

_scannerController.startCamera();

```
*2、打开预览/识别'条码'

```

_scannerController.startCameraPreview();

```

*3、关闭预览/识别'条码'

```

_scannerController.stopCameraPreview();

```

*4、关闭相机设备

```

_scannerController.stopCamera();

```

*5、打开手电筒

```

_scannerController.openFlash();

```

*5、关闭手电筒

```

_scannerController.closeFlash();

```

*5、切换手电筒
