Project Structure

This project was developed with Clean Architecture with MVVM, making use of SOLID principles so that each layer has its responsibility and is testable, with the following layers:

• app: Application module
  • mappers: Models and DTOs adapters
  • frameworks: Storage database and API services libraries
  • presentation: Views and view models
• core: Business Logic module
  • data: business contracts and commom classes
  • domain: business classes and objects
  • usecases: User interactors classes

This project also uses Cached Data First Strategy, improvement a better user experience. In this case, if we have some data storaged in app, we should load it at first instead fetch it from server. If we don't, we fetch it from server and then storaged in app.
