flutter_edge_ai_embeddings 2.2.2

Embedding tokenizers for flutter_edge_ai: Gemma SentencePiece and BERT WordPiece, as a registrable provider. The pipeline they feed lives in flutter_edge_ai.

2.2.2

• Require flutter_edge_ai 2.x.

2.2.1

• Renamed from flutter_gemma_embeddings.
• README: engine authors pass activeBackend: to ForwardPassDescriptor.

2.2.0

• Register GemmaEmbeddingTokenizers() via initialize(embeddingTokenizers:) — engines no longer name a tokenizer.
• The web bundle moved to flutter_gemma_litertlm; re-copy the four JS files from there.
• BREAKING on web: web_embedding_model.dart moved to flutter_gemma_litertlm — bump it to 1.8.0.

2.1.1

• Lift the dart_sentencepiece_tokenizer cap — 1.4.1 is now required, not excluded.

2.1.0

• Add a SigLIP2 text-embedding profile (no BOS, single trailing EOS, lowercased, fixed 64-token width).
• No longer pulls dart:io into the web graph; fromPath throws UnsupportedError there.
• Cap dart_sentencepiece_tokenizer below 1.4.0, which rejects EmbeddingGemma's and SigLIP2's tokenizer.json.

2.0.0

• BREAKING: runtime-agnostic embedder; LiteRtEmbeddingBackend moved to flutter_gemma_litertlm.
• Add tokenizer-factory seam (ForwardPassDescriptor.tokenizerFactory) so engines can bring WordPiece too.
• Add EmbeddingForwardPass.outputContract override + ForwardResult.attentionMask for the mask thread.
• Add WordPieceEmbeddingTokenizer (BERT-style, e.g. MiniLM) alongside the existing Gemma SentencePiece adapter.

1.0.4

• internal: run on the flutter_gemma_litertlm LiteRT engine (no API change).

1.0.3

• Migrate to LiteRT v0.14.0 3-arg LiteRtCreateModelFromFile (adds LiteRtEnvironment); native-v0.14.0.

1.0.2

• Realign the shared LiteRT-LM native bundle to native-v0.13.1-b (#364). No API change.

1.0.1

• Rebuild on native-v0.13.1-a (shares the LiteRT-LM native bundle; restores NPU dispatch libs, #155). No embeddings API change.
• Point homepage to fluttergemma.dev. No code change.

1.0.0

• Stable 1.0.0; spec imports redirected off the dart:io mobile lib for a wasm-clean web graph.

1.0.0-rc.1

• Initial release: on-device text embeddings (Gecko / EmbeddingGemma .tflite) via the LiteRT C API + dart:ffi.
• Provides LiteRtEmbeddingBackend (EmbeddingBackendProvider); forward pass runs on a background isolate.
• Autonomous (no dependency on flutter_gemma_litertlm); shares the LiteRT-LM native library when both are present.
• Android, iOS, macOS, Linux, Windows + web (LiteRT.js).
