final String data = await FlutterQrReader.imgScan(File);

QrReaderView(

  height: 350,
  callback: (container) {},
)
// 打开手电筒
..setFlashlight
// 开始扫码
..startCamera
// 结束扫码

Widget build(BuildContext context) {
    return new Scaffold(
      body: QrcodeReaderView(key: qrViewKey, onScan: onScan),
    );
}

GlobalKey<QrcodeReaderViewState> qrViewKey = GlobalKey();

Future onScan(String data) async {
    await showCupertinoDialog(
      context: context,
      builder: (context) {
        return CupertinoAlertDialog(
          title: Text("扫码结果"),
          content: Text(data),
          actions: <Widget>[
            CupertinoDialogAction(
              child: Text("确认"),
              onPressed: () => Navigator.pop(context),
            )
          ],
        );
      },
