Step 3:

This project uses freezed library that works with code generation, execute the following command to generate files:

flutter packages pub run build_runner build --delete-conflicting-outputs

or watch command in order to keep the source code synced automatically:

flutter packages pub run build_runner watch

i10n support

More information about using i10n, you can find in documentation.

Architecture

This project is based on a combination of Clean Architecture and BLoC pattern.

Every “feature” of the app, will be divided into 3 layers – presentation, domain and data

Presentation:

This layer is responsible for UI, and everything which is connected with user interactions. In most of the cases, it will be divided into 3 packages:

  • cubit – with all cubits and states used in this feature, responsible for controlling current state of widgets
  • components – all smaller widgets used in this feature, which could be easily reused in many places
  • pages – which defines all high level scaffolds, in most cases with some AppBar which includes title and navigation button

Domain: This layer will contain only the core business logic (use cases) and business objects (entities). It should be totally independent of every other layer.

Domain layer will be divided into 3 packages:

  • entities – all business objects and holders used in a specific features,
  • repositories – which should contain only abstract definition of repository,
  • usecases – with classes which encapsulate all the business logic of a particular use case of the app.

Data:

The data layer consists of a Repository implementation (the contract comes from the domain layer) and data sources.

This layer contains 2 packages:

  • models – dart representation of API models, with proper methods for serialization vs deserialization
  • dataproviders – the data provider’s responsibility is to provide raw data. The data provider should be generic and versatile.
  • repositories – are a wrapper around one or more data providers, should cover all repositories defined inside domain layer
