Folder Structure explanation

The lib folder is divided into three folders; core, ui, and config. Core contains all the files associated with the logic. Ui contains all the files associated with the ui. Config is for configurations.

• core

  • constants
    • Holds app constants and enums.
  • models
    • Contains all the plain data models.
  • services
    • Contains the classes that interacts directly with an API (REST API or Firebase, a device API).
  • view_models
    • contains a view model for each view which will act as an interface (transforms or manipulates the data that the API provides) between a view and services.

• ui

  • utils
    • Contains functions or constants that are used in multiple other UI files.
  • views
    • Contains the main app screens.
  • widgets
    • Contains widget files that are too big to keep in the view files.
    • Usually contains shared widgets that are classes extending stateless widgets.

• config

  • configuration files for routing, providers, and locators
