Building Offline-First Flutter Apps with Couchbase Lite
summary
A small chat app demonstrates an embedded JSON NoSQL database Couchbase Lite with the Dart SDK and Flutter bindings using packages CBL CBL Flutter and CBL Flutter C/E, saving messages as documents (immutable by default, call toMutable to change), observing queries reactively with SQL++ result sets, and running a continuous replicator against a local Sync Gateway and Couchbase Server to sync between iOS and macOS in real time. The demo adds editable messages, creates a full-text search index with stemming and prefix search, and shows it working live.
