Flutter Blue Setting Notifications

I found https://github.com/Sensirion/smart-gadget-flutter/tree/master/lib and I was able to fix my problem using the following code:

      for(BluetoothService service in services) {        for(BluetoothCharacteristic c in service.characteristics) {          if(c.uuid == new Guid("0000ffe1-0000-1000-8000-00805f9b34fb")) {            _setNotification(c);          } else {            print("Nope");          }        }      }

This was added in the _connect function.

_connect(BluetoothDevice d) async {    device = d;// Connect to device    deviceConnection = _flutterBlue        .connect(device, timeout: const Duration(seconds: 4))        .listen(      null,      onDone: _disconnect,    );// Update the connection state immediately    device.state.then((s) {      setState(() {        deviceState = s;      });    });// Subscribe to connection changes    deviceStateSubscription = device.onStateChanged().listen((s) {      setState(() {        deviceState = s;      });      if (s == BluetoothDeviceState.connected) {        device.discoverServices().then((s) {         services = s;          for(BluetoothService service in services) {            for(BluetoothCharacteristic c in service.characteristics) {              if(c.uuid == new Guid("0000ffe1-0000-1000-8000-00805f9b34fb")) {                _setNotification(c);              } else {                print("Nope");              }            }          }          setState(() {            services = s;          });          _getServices();        });      }    });  }
