有些二维码或条码图片能扫描，有些扫描不了，我试了别的扫描软件都能扫描出来。还有就是扫描速度偏慢一些，有时要左右移动好久才能识别

RScanCameraController _controller;
await _controller.stopScan();
await _controller.startScan();

调用stopScan，然后在另一个点击事件中调用startScan，就停止扫描了，这也是一个问题

调用stopScan，然后在另一个点击事件中调用startScan，还是不能开始扫描了

ImageScanHelper中 hints.put(DecodeHintType.POSSIBLE_FORMATS, BarcodeFormat.QR_CODE)这边不能直接放BarcodeFormat.QR_CODE，要把这个放到List list中,hints.put(DecodeHintType.POSSIBLE_FORMATS， list)。
图片识别的效果不是很好
