Function for animated display of cars on the map

// Map existing markers for (var marker in _markers) { existingMarkers[marker.carId] = marker.placemarkId; }

// Prepare new markers and update existing ones for (var car in cars) { final geometry = _createGeometry(car); newMarkers[car.id] = geometry;

if (existingMarkers.containsKey(car.id)) {
  // Animate movement from current position to new position
  final placemarkId = existingMarkers[car.id]!;
  // Assuming we have previous position stored, animate to new position
  // For simplicity, directly update to new geometry
  plugin.updatePlacemark(placemarkId, geometry);
} else {
  // Add new marker
  final placemarkId = plugin.addPlacemark(geometry);
  // Store the marker with its carId if needed
}

}

// Remove markers that are no longer present for (var carId in existingMarkers.keys) { if (!cars.any((car) => car.id == carId)) { plugin.removePlacemark(existingMarkers[carId]!); } } }
