sendOperation method

@override Future<void> sendOperation(Operation operation)

Sends an operation to the server/peers.

Implementation

@override
Future<void> sendOperation(Operation operation) async {
  const transientOps = {'CURSOR_MOVE', 'GHOST_UPDATE', 'PRESENCE_UPDATE'};
  if (transientOps.contains(operation.type)) {
    if (_innerClient != null && _isConnected) {
      await _innerClient!.sendOperation(operation);
      return;
    }
    print('OfflineClient: Dropping transient operation ${operation.type} because offline');
    return;
  }

  // Legacy: Normalize data if it uses old keys or formats, but keep them robust
  if (operation.data.containsKey('start')) {
    final startVal = operation.data['start'];
    if (startVal is String || startVal is int) {
      operation.data['start_date'] = startVal;
