listen method

@override Future<void> listen(String eventName)

Listens to a specific event from the socket.

Throws SocketNotConnectedException if not connected. Throws SocketEventException if event listening fails.

Implementation

@override
Future<void> listen(String eventName) async {
  try {
    if (eventName.isEmpty) {
      throw SocketEventException('Event name cannot be empty');
    }

    await methodChannel.invokeMethod('listen', {'event': eventName});
  } on PlatformException catch (e) {
    _handlePlatformException(e, 'listen');
  } catch (e) {
    if (e is SocketException) {
      rethrow;
    }
    throw SocketEventException('Unexpected error while listening to event "$eventName": $e');
  }
}
