This plugin integrates with the ZBar library, exposing a JavaScript interface for scanning barcodes (QR Code, EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 39, Interleaved 2 of 5, etc). In this fork a button has been added to turn off and on device flash. In addition the plugin can now handle the device orientation change.
