# recognition_qrcode

识别图片中的二维码的flutter插件，简单好用
![](./demo.gif)
## Getting Started
采用GoogleMLKit框架，支持识别条形码、二维码等，支持识别包含多个二维码、条形码的图片
### 使用方法
```
$ flutter pub add recognition_qrcode
```
或者：
```
dependencies:
  recognition_qrcode: ^2.0.0
```

```
import 'package:recognition_qrcode/recognition_qrcode.dart';

//如果使用默认配置可以不配置config
 RecognitionQrcode.config(
      // icon: "assets/bx-right-arrow.png", //箭头图标: 传路径
      iconWidth: 30, // 箭头图标大小
      iconHeight: 30,// 箭头图标大小
      cancelTitleFontSize: 16, // 右上角取消按钮文字大小
      cancelTitle: "取消",// 右上角取消按钮文字
  );
//参数 img: 支持base64、url、filePath三种方式
RecognitionQrcode.recognition(
                        "https://tool.oschina.net/action/qrcode/generate?data=1231231231&output=image%2Fpng&error=L&type=0&margin=7&size=4.png").then((result) {
    print("recognition: $result");
  }).catchError((onError) {
    print("catchError:$onError");
});
```
由于googleMLKit的原因，不支持iOS模拟器上运行

### 鸿蒙适配

1. 复制 `example/ohos/entry/src/main/ets/entryability/CodeAbility.ets` 到你的项目（同路径）
2. 复制 `example/ohos/entry/src/main/ets/pages/CodePage.ets` 到你的项目（同路径）
3. 复制 `example/ohos/entry/src/main/resources/base/media/bx_right_arrow.png` 到你的项目（同路径）
4. 修改你的项目的 `entry/src/main/module.json5`，在 `abilities` 中添加：

```json
{
 "name": "CodeAbility",
 "srcEntry": "./ets/entryability/CodeAbility.ets",
 "description": "$string:EntryAbility_desc",
 "icon": "$media:icon",
 "label": "$string:EntryAbility_label",
 "startWindowIcon": "$media:icon",
 "startWindowBackground": "$color:start_window_background",
 "exported": true
}
```

例子项目依赖 `image_picker`，如果在 `windows` 上遇到`长路径限制`，请将

```yaml
# ohos 适配版 image_picker
image_picker:
 git:
  url: https://gitee.com/openharmony-sig/flutter_packages.git
  path: packages/image_picker/image_picker
```

修改为：

```yaml
# ohos 适配版 image_picker
image_picker:
 path: "<your_path>/flutter_packages/packages/image_picker/image_picker"
```
