cortex #

A Flutter plugin to work with Cortex library

Platform Support #

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"}');
