What is sqflite in Flutter?

sqflite is the most popular Flutter plugin for using SQLite, a local relational database. It is supported on Android, iOS, and macOS. You can create tables, run SQL queries (SELECT, INSERT, UPDATE, DELETE), use transactions, and perform migrations. It works well for structured data like user profiles, cached API responses, or offline-first apps. For a more Dart-idiomatic ORM approach on top of sqflite, consider using the drift (formerly Moor) package.
