Master Isar Database in Flutter: A Powerful NoSQL Local Storage Solution for Your Flutter Apps

Learn to integrate Isar, a fast and efficient NoSQL database, into your Flutter apps. This course will guide you through setting up Isar, creating collection models as database tables, and handling automatic schema migration along with implementing custom data migration logic. You'll perform essential CRUD (Create, Read, Update, Delete) operations while effectively managing transaction and CRUD operation failures. You'll also write unit and integration test cases to validate database functionality and ensure data integrity. Explore the Isar Database Inspector to inspect and modify data in real-time, and learn to use transactions to group multiple operations, ensuring consistency. Discover how to actively listen for changes in your database using watchers, improve performance by running database operations in different isolates, and link entities across collections to keep data in sync. Finally, you'll master writing efficient queries for sorting, filtering, searching, and defining indexes for optimized database performance.
