generateEmbedding method

@override Future<List<double>> generateEmbedding(String text, { TaskType taskType = TaskType.retrievalQuery, })

Generate embedding vector for given text.

taskType controls the prefix applied before embedding:

• TaskType.retrievalQuery (default) — for search queries
• TaskType.retrievalDocument — for document indexing

Implementation

@override
Future<List<double>> generateEmbedding(
  String text, {
  TaskType taskType = TaskType.retrievalQuery,
}) async {
  _assertNotClosed();
  await _ensureInitialized();

  try {
    if (taskType == TaskType.retrievalDocument) {
      return await LiteRTWebEmbeddings.generateDocumentEmbedding(text);
    }
    return await LiteRTWebEmbeddings.generateEmbedding(text);
  } catch (e) {
    if (kDebugMode) {
      debugPrint('❌ Failed to generate embedding: $e');
    }
    rethrow;
  }
}
