No devices are found

[jcm10x1]

Here is the code I have to locate found devices. "FOUND A DEVICE" is never printed. Other packages and apps do find plenty of devices. I am currently on Android 10 and the quick_blue version is 0.4.1+1.

  @override
  void initState() {
    super.initState();

    startScanning();
    print('INIT STATE');
  }

  void startScanning() async {
    final location = await Permission.location.status;
    if (!location.isGranted) {
      await Permission.location.request();
    }
    final bluetooth = await Permission.bluetooth.status;
    if (!bluetooth.isGranted) {
      await Permission.bluetooth.request();
    }

    if (await QuickBlue.isBluetoothAvailable() == false) {
      print('BLUETOOTH NOT AVAILABLE');
      return;
    }
    QuickBlue.scanResultStream.listen(
      (result) {
        print('FOUND A DEVICE');
        if (!devices.contains(result) && result.name != '') {
          setState(() {
            print(result.name);
            devices.add(result);
          });
        }
      },
      onError: (e) {
        print('ERROR: $e');
      },
      onDone: () => print('DONE'),
    );
    QuickBlue.startScan();
    print('STARTED SCANNING');
  }
