[BUG] barcode found, but QRViewController does not get it and does not process it

[IGMendoza]

Bug Setting up the function:

void _startQRReadingStream(QRViewController controller) {
    this.controller = controller;
    controller.scannedDataStream.listen((scanData) {
      processQRScan(scanData.code!);
    });
  }

The QR codes are processed most of the time. However, sometimes the function processQRScan(scanData.code!); is not called every time, yet the console spits out that it has indeed found a barcode every time (see Output below)

Output D/DecoderThread(26526): Found barcode in 30 ms D/DecoderThread(26526): Found barcode in 27 ms D/DecoderThread(26526): Found barcode in 27 ms D/DecoderThread(26526): Found barcode in 28 ms D/DecoderThread(26526): Found barcode in 44 ms D/DecoderThread(26526): Found barcode in 28 ms D/DecoderThread(26526): Found barcode in 17 ms
