Using LED with ngcordova barcode scanner -


when trying use barcode scanner in bad lighting conditions, beneficial if possible light led/flash comes phone/tablet

i have found out zxing library used ngcordova barcodescanner automatically supports feature (although not yet documented). source code states if click volume button led/flash if present lit up. clicking volume down button turn off led/flash.

although can not 100% certain, given life of zxing library captureactivity think barcodescanner using able use functionality assuming flash present.

hope helps someone.
