When I use noDuplicates I can't scan the same barcode even on different launch

[shymek]

Whenever I started using detection speed of noDuplicates and I properly scan a barcode, pop the scanning view and navigate again and create a new instance of MobileScanner it will not let me scan that barcode.

I tested it multiple times and scanning 2 different barcodes each time works perfectly.
Changing the speed to normal also fixes this.

Am I using the scanner incorrectly?

  Widget buildBody(BuildContext context) {
    return BlocBuilder<ScannerBloc, ScannerState>(
      builder: (context, state) {
        return SizedBox(
          height: MediaQuery.of(context).size.height,
          width: MediaQuery.of(context).size.width,
          child: MobileScanner(
            onDetect: (capture) => _onDetect(context, capture),
            controller: MobileScannerController(
              formats: [
                BarcodeFormat.ean13,
                BarcodeFormat.ean8,
              ],
            ),
          ),
        );
      },
    );
  }

This is the code I am using without the noDuplicates speed which fixes the issue. This is a StatelessWidget if that matters.
