Implementation

void asyncUpdateToFromData(
  final void Function(GemError err) onCompleteCallback,
) {
  final EventDrivenProgressListener listener = EventDrivenProgressListener();
  GemKitPlatform.instance.registerEventHandler(listener.id, listener);

  listener.registerOnCompleteWithDataCallback((
    final int err,
    final _,
    final __,
  ) {
    onCompleteCallback(GemErrorExtension.fromCode(err));
  });

  final OperationResult resultString = objectMethod(
    _pointerId,
    'RouteTrafficEvent',
    'asyncUpdateToFromData',
    args: listener.id,
  );

  final int error = resultString['gemApiError'];
  if (error != 0) {
    onCompleteCallback(GemErrorExtension.fromCode(error));
  }
}
