+# sqflite ffi async
+
+[sqflite](https://pub.dev/packages/sqflite) based ffi implementation. Based
+on [`sqlite_async`](https://pub.dev/packages/sqlite_async). Thanks to [PowerSync](https://github.com/powersync-ja)
+
+* Works on Linux, MacOS and Windows on both Flutter and Dart VM.
+* Works on iOS and Android (using [sqlite3_flutter_libs](https://pub.dev/packages/sqlite3_flutter_libs) - Thanks
+  to [Simon Binder](https://github.com/simolus3))
+
+## Caveats
+
+This is a work in progress.
