Controller.pause doesn't stop the scanning of barcode

[AliYar-Khan]

I am trying to pause the scanning of barcodes once it detects a barcode

  MobileScanner(
     controller: controller,
     onDetect: (capture) {
           final List<Barcode> barcodes = capture.barcodes;
           if (barcodes.isNotEmpty) {
               controller.pause();
               getProduct(barcodes.first.rawValue);
           }
      },
 ),

But it doesn't stop scanning and keep reading barcode

controller.pause() should stop scanning I make the code await and use .then as well but nothing seems to work

The pause method only pauses the camera preview iirc. What if you pause the stream subscription for the barcode stream?

@navaronbracke how to pause the stream ?

[navaronbracke]

I see that you are using onDetect. You can manually listen to the barcodes stream of the controller and pause the StreamSubscription that you get from that.

Although, maybe we should also pause the underlying stream source when pause() is called for the camera preview.
