Usage

To use this plugin, add cortex as a dependency in your pubspec.yaml file.

This will expose three classes of Cortex events through four different streams.

• ResponseEvents describe the response from Cortex for each request.
• WarningEvents describe the warning message from Cortex.
• DataStreamEvents describe the data stream event when subsribe data (eeg, motion, ...) from Cortex.

Each of these is exposed through a BroadcastStream: responseEvents, warningEvents, and dataStreamEvents, respectively.

It also provides 3 functions to work with Cortex.

• startCortex tell Cortex to start working.
• authenticateWithCortex(clientId) will open a webview for user login and get authentication code from Emotiv backend server.
• sendRequestToCortex will send request to Cortex with json format.
• function stop cortex is implemented in Java layer when application terminates, we don't export it to dart layer.

Example

import 'package:cortex/cortex_plugin.dart';

responseEvents.listen((event) {
  print(event);
});

warningEvents.listen((event) {
  print(event);
});

dataStreamEvents.listen((event) {
  print(event);
});


sendRequestToCortex('{ "id": 1, "jsonrpc": "2.0", "method": "queryHeadsets"}');

Also see the example subdirectory for an example application that uses to work with real device. Remember to add EmotivCortexLib.aar to your main project.

Attention

Only Emotiv's partner can get EmotivCortexLib.aar for now. But we have the plan to publish it in the future.
