🐛 [meidiapipe_text] Null check failed by cosineSimilarity

It seems like the embedding pointer becomes null If It is not created from the embedder.

final textEumbedResult = await embedder.embed(text);

final embedding = Embedding.float(
            Float32List.fromList(te),
            headIndex: 1,
 );

final similarity = await embedder.cosineSimilarity(
            textEumbedResult.embeddings.first,
            embedding,
  );  

print("similarity: $similarity");
