Overview
sqflite_migration is a Flutter package that facilitates database migrations for SQLite using the sqflite plugin. It provides a structured approach to managing schema changes over time, ensuring data integrity during app updates. The library allows developers to define migration scripts that run automatically when the database version changes, simplifying version control of local databases. It integrates seamlessly with sqflite and supports Android, iOS, and macOS platforms.
