1. DSBarcodeScannerConfig *config = [[DSBarcodeScannerConfig alloc] init];
   config.isCloseButtonVisible = false;
   DSRect *region = [[DSRect alloc] init];
   region.left = 0.15;
   region.top = 0.3;
   region.right = 0.85;
   region.bottom = 0.7;
   config.scanRegion = region;
   config.isTorchButtonVisible = false;
   config.isScanLaserVisible = false;
   config.isCameraToggleButtonVisible = true;
   

2. let config = BarcodeScannerConfig()
   config.isCloseButtonVisible = false
   let region = Rect()
   region.left = 0.15
   region.top = 0.3
   region.right = 0.85
   region.bottom = 0.7
   config.scanRegion = region
   config.isTorchButtonVisible = false
