addDocument method

Implementation

@override
Future<void> addDocument({
  required String id,
  required String content,
  String? metadata,
}) async {
  // Generate embedding for content first
  if (initializedEmbeddingModel == null) {
    throw StateError(
      'No embedding model is active. addDocument(content:) and '
      'searchSimilar(query:) auto-embed text, which requires an embedding '
      'model. Install and activate one with FlutterGemma.installEmbedder(...) '
      '(or modelManager.setActiveModel) before calling these methods — or '
      'pass a precomputed vector to addDocumentWithEmbedding(embedding:).',
    );
  }
  final embedding = await initializedEmbeddingModel!.generateEmbedding(
    content,
    taskType: TaskType.retrievalDocument,

  await addDocumentWithEmbedding(
    id: id,
