Flutter and Dart And obviously flutter and dart 😅
The data layer is the outermost layer of the application and is responsible for communicating with the server-side or a local database and data management logic. It also contains repository implementations.
Describes the process of acquiring and updating the data. Consist of remote and local Data Sources. Remote Data Source will perform HTTP requests on the API. At the same time, local Data sources will cache or persist data.
The bridge between the Data layer and the Domain layer. Actual implementations of the repositories in the Domain layer. Repositories are responsible for coordinating data from the different Data Sources.
The domain layer is responsible for all the business logic. It is written purely in Dart without flutter elements because the domain should only be concerned with the business logic of the application, not with the implementation details.
Describes the logic processing required for the application. Communicates directly with the repositories.
Abstract classes that define the expected functionality of outer layers.
The presentation layer is the most framework-dependent layer. It is responsible for all the UI and handling the events in the UI. It does not contain any business logic.
Widgets notify the events and listen to the states emitted from the StateNotifierProvider
.
Describes the logic processing required for the presentation.
Communicates directly with the Providers
from the domain layer.
main.dart
file has services initialization code and wraps the rootMyApp
with aProviderScope
main/app.dart
has the rootMaterialApp
and initializesAppRouter
to handle the route throughout the application.services
abstract app-level services with their implementations.- The
shared
folder contains code shared across featurestheme
contains general styles (colors, themes & text styles)model
contains all the Data models needed in the application.http
is implemented with Dio.storage
is implemented with SharedPreferences.- Service locator pattern and Riverpod are used to abstract services when used in other layers.
