Events Streamers #
Most of the plugin functions are built as event streamers, every headset state or data is emitted as events.
Note that: the plugin provides all events interfaces for both StreamSDK and AlgoSDK, there are common events between both SDKs that return 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(() {});
}
});
