#### 商米手持pda设备（android）主要应用于仓储，快递等ERP系统中。这个插件方便大家简单获取到它的红外头扫描到的条码数据

# 引入依赖


```dart
dependencies:
  sm_scan: ^5.0.0 
```

# 如何使用

方式一： 在页面中混入`ShangmiScanMixin`，只需简单两步
```dart

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

// 第一步：混入ShangmiScanMixin
class _MyAppState extends State<MyApp> with ShangmiScanMixin<MyApp> {


  String _code = '';

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('扫码例子'),
        ),
        body: Center(
          child: Text('扫描到数据：$_code'),
        ),
      ),
    );
  }

  /// 第二步：实现shangmiCodeHandle方法，当红外扫码头扫到数据执行的方法
  ///
  /// code: 表示扫码到的数据
  ///
  @override
  Future<void> shangmiCodeHandle(String code) async {
    /// 编写你的逻辑
    print('扫描到数据：$code');
    setState(() {
      _code = code;
    });
  }
}
```

方式二： 在任何地方监听数据

```dart

    /// 在任何地方监听扫描数据
    ShangMiScanUtil().listen((value) {
      print("扫描到数据：$value");
    });

    /// 不需要的时候记得关闭它
    ShangMiScanUtil().cancel();
```
