deleteSegment method

Implementation

@override

  try {
    Collection collection = await client.getCollection(name: collectionName);//, embeddingFunction: embeddingFunction);
    await collection.delete(ids: [segmentId]);

    List<String> segmentIdOrder = (jsonDecode(metadata[segmentIdOrderKey]) as List<dynamic>).map((segmentId)=> (segmentId as String)).toList();
    segmentIdOrder.remove(segmentId);
    metadata[segmentIdOrderKey] = jsonEncode(segmentIdOrder);
    await collection.modify(name: collectionName, metadata: metadata);
