Using SimpleBarcodeScanner with continuous: true,isShowFlashIcon: true, does not display the Flash Icon button and Close Button

[minhluankt]

Hello everyone, I am using SimpleBarcodeScanner with continuous: true for continuous scanning, with a 2-second delay for each scan. I have set isShowFlashIcon to true to enable the flash, but my Android device does not display the close button or the flash toggle button, and the delayMillis is not working. Please help me. How can I make the buttons (close and flash) work, and how can I add a widget to enable/disable continuous scanning (I plan to add a feature to toggle continuous scanning on the screen)? Thank you.
