FlutterBluePlus.scanResults.listen((List<ScanResult> results) {
  results.forEach((result) {
    final deviceID = result.device.platformName;
    if (deviceID == "MindWave Mobile") {
      MindwaveMobile2.instance.init(deviceID);
    }
  });
});

Connect & Disconnect

Events Streamers

Most of the plugin functionalties are built as event streamers, every headset state or data are emitted as events.

Note that: the plugin provides all events interfaces for both StreamSDK and AlgoSDK, there is common events between both SDK's that returns exactly the same results, you shall use any of them.

- Headset State

Emits the current state of the Headset.

_headsetStateSubscription = MindwaveMobile2.instance.onStateChange().listen((state) {
  _headsetState = state;
  if (state == HeadsetState.DISCONNECTED) {
    MindwaveMobile2.instance.disconnect();
  }
  if (mounted) {
    setState(() {});
  }
});

- StreamSDK events

var signalQualitySubscription = MindwaveMobile2.instance.onSignalQualityUpdate()
  .listen((int signalQuality) {
      // Handle signalQuality
  });

var attentionSubscription = MindwaveMobile2.instance.onAttentionUpdate()
  .listen((int attention) {
      // Handle attention
  });

var meditationSubscription = MindwaveMobile2.instance.onMeditationUpdate()
  .listen((int meditation) {
      // Handle meditation
  });

var bandPowerSubscription = MindwaveMobile2.instance.onBandPowerUpdate()
  .listen((BandPower bandPower) {
      // Handle bandPower
  });

var rawSubscription = MindwaveMobile2.instance.onRawUpdate()
  .listen((List<int> rawData) {
      // Handle rawData
  });

- AlgoSDK events

var algoStateReasonSubscription = MindwaveMobile2.instance.onAlgoStateReasonChange()
  .listen((Map stateReason) {
      // Handle stateReason
      // The returned map is of the form
      // {"State": AlgoState, "Reason": AlgoReason}
  });

var algoAttentionSubscription = MindwaveMobile2.instance.onAlgoAttentionUpdate()
  .listen((int attention) {
      // Handle attention
  });

var algoMeditationSubscription = MindwaveMobile2.instance.onAlgoMeditationUpdate()
  .listen((int meditation) {
      // Handle meditation
  });

var algoBandPowerSubscription = MindwaveMobile2.instance.onAlgoBandPowerUpdate()
  .listen((AlgoBandPower algoBandPower) {
      // Handle algoBandPower
  });

var algoSignalQualitySubscription = MindwaveMobile2.instance.onAlgoSignalQualityUpdate()
  .listen((int signalQuality) {
      // Handle signalQuality
  });

var algoBlinkSubscription = MindwaveMobile2.instance.onBlink()
  .listen((int blinkStrength) {
      // Handle blinkStrength
  });
