notification/domain

Notification usecases in Flutter Clean Architecture encapsulate actions like fetching notifications and registering FCM tokens as discrete classes. This approach standardizes data access through repository contracts, making application logic easier to test and orchestrate independently.

Managing in-app notifications in Dart requires repository contracts defining methods like getNotifications, markRead, markAllRead, getUnreadCount, and registerFcmToken to standardize data access and handle notification states.

Register FCM tokens in a Flutter domain layer by implementing a specific usecase that exposes a registerFcmToken method. This usecase interacts with a defined repository contract to handle device token registration for push delivery with clear inputs and error handling.

Yes, the notification domain layer supports tracking unread notification counts by defining a specific getUnreadCount usecase. This usecase queries the repository contract to retrieve and expose the current number of unread notifications.

Define repository contracts for notifications when building scalable Flutter apps needing consistent, testable flows. This abstraction separates domain logic from data sources, allowing teams to implement standardized actions like marking read without coupling to specific APIs.
