Implement offline data persistence in Flutter by structuring data access around repositories and a dedicated SQLite Database Service to store, query, and manage large structured data locally on the device.

The best way to structure domain models for offline-first Flutter apps is using a repository and services separation, ensuring a single source of truth and clean data mapping between API or database models and domain models.

Offline synchronization in Flutter reads local SQLite data first, then updates from remote sources, keeping the local store consistent and ensuring safe offline-first workflows with eventual consistency.

Yes, you can apply the MVVM architecture pattern in Flutter by wiring your ViewModels to repositories that handle domain modeling and persist data through a dedicated SQLite Database Service.

You need a dedicated Database Service for local storage in Flutter when your mobile application requires a single source of truth, offline-first workflows, and the ability to store large structured data locally.

While SQLite provides robust local persistence, offline data synchronization in Flutter requires careful architectural planning to maintain eventual consistency and manage clean data mapping between API and domain models.
