flutter_gemma_rag_sqlite #
SQLite + HNSW on-device RAG vector store for flutter_gemma.
Opt-in package implementing VectorStoreRepository:
- Native (Android/iOS/macOS/Linux/Windows):
SqliteVectorStore—sqlite3(dart:ffi) + HNSW. - Web:
WebSqliteVectorStore— wa-sqlite (WASM) + HNSW.
Usage #
import 'package:flutter/foundation.dart' show kIsWeb;
import 'package:flutter_gemma/flutter_gemma.dart';
import 'package:flutter_gemma_rag_sqlite/flutter_gemma_rag_sqlite.dart';
await FlutterGemma.initialize(
vectorStore: kIsWeb ? WebSqliteVectorStore() : SqliteVectorStore(),
);
Web setup #
On web the wa-sqlite engine is loaded from a <script> in your app's
web/index.html <head> (it exposes the global the package binds to). Pin a
release tag and include the Subresource Integrity hash so a CDN compromise
cannot inject code:
<script type="module"
src="https://cdn.jsdelivr.net/gh/DenisovAV/flutter_gemma@<tag>/web/sqlite_vector_store.js"
integrity="sha384-IHmYOhCWsp68Nh9VJD6E6eFk2uLipbclH2+nLjc2GdGQKral9Re53FShwFStJms3"
crossorigin="anonymous"></script>
The worker (sqlite_vector_store_worker.js, integrity
sha384-065e421XLyAFCTrUgXx4D1tSVNDft1/3bbpauywRiVEFaCY0BE6TrkHD2CxNt6R+) is
fetched by the main script from the same CDN path — no separate tag needed.
Regenerate a hash after upgrading the JS with:
openssl dgst -sha384 -binary web/sqlite_vector_store.js | openssl base64 -A
Native platforms need no setup — sqlite3 bundles its own native library.
