Chapter Summary

Summarize project structures, automation commands, and code snippets explored in this chapter.

Summarizing architecture, automation, and coding snippets

In this chapter, we learned to structure our projects in getx_pattern and clean architectures to make our codebase easy to maintain. We explored Get CLI and all its commands that help us automate tedious tasks and generate files in the project structure of choice. Finally, we walked through some of the most helpful code snippets provided by GetX Snippets. These reduce boilerplate and make development more efficient. This summary lesson will revisit the concepts and tools covered throughout the chapter. So, let’s go ahead and review all the lessons, one at a time.

Project structure

  • Overview:

    • Project structure is crucial for scalability and maintainability.

    • GetX ecosystem recommends getx_pattern and clean structures.

  • The getx_pattern architecture:

    • The data folder:

      • Handles data-related operations like fetching, caching, and database interactions.

    • The modules folder:

      • Contains independent app components with views, controllers, and bindings in subfolders.

      • Helps compartmentalize and scope components to specific pages.

    • The routes folder:

      • Defines routes and navigation logic, keeping it organized as the app grows.

  • The clean architecture:

    • The domain folder:

      • Stores core application logic, abstract and decoupled from UI and services.

      • Contains fundamental models, business logic, and reusable methods.

    • The infrastructure folder:

      • Contains dal (Data access layer), navigation, and theme subfolders.

      • dal: Organized into daos (Data access objects) and services. Interacts with data sources and abstracts out the logic.

      • navigation: Manages routes, navigation logic, and bindings.

      • theme: Stores theme data like color schemes and text themes.

    • The presentation folder:

      • Represents the presentation layer with folders for each page.

      • Contains widgets and controllers relevant to each page.

  • Conclusion:

    • Organizing code in recommended structures enhances maintainability.

    • The Get CLI tool supports these structures, facilitating efficient project setup and management.

Automation with Get CLI

  • Overview:

    • Automates tasks related to boilerplate code.

    • Structures projects in a scalable manner and provides commands for file generation.

  • Create a project:

    • get create project generates a default Flutter project with optional configurations.

    • get create project:project_name allows direct naming of the project.

  • Initialize the project structure:

    • get init sets up the project structure using getx_pattern or clean architecture.

    • Creates folders for data, views, controllers, bindings, and navigation.

  • Create a page:

    • get create page:page_name (getx_pattern) or get create screen:screen_name (clean) generates all necessary files and boilerplate for a new page.

    • Includes view, controller, and binding classes and updates navigation routes.

  • Create a view:

    • get create view:view_name on page_name adds a new view file to a specific page folder.

    • Generates basic widget boilerplate.

  • Create a controller:

    • get create controller:controller_name on page_name adds a new controller file to a specific page folder.

    • Includes life cycle methods and a sample reactive variable.

  • Generate the model:

    • get generate model on page_name with path/to/json_file or get generate model on page_name from 'json_file_url' creates a model from JSON.

    • Generates a model class with serialization and deserialization methods.

    • Also generates a provider class for HTTP operations.

  • Install packages:

    • get install package_name installs a package.

    • Multiple packages and specific versions can be installed by listing them with colons for versions.

  • Remove packages:

    • get remove package_name removes a package.

    • Multiple packages can be removed by listing them.

Most useful GetX Snippets

  • Overview:

    • GetX Snippets is an IDE extension that reduces boilerplate code.

    • Useful for projects using the getx_pattern structure.

  • Flutter widgets:

    • getfab: Creates a FloatingActionButton with default settings.

    • getbutton: Creates a MaterialButton with a predefined style and an onPressed function.

  • GetX widgets:

    • getx: Initializes a controller and builds a widget based on the controller’s state.

    • getobxvalue: Generates an ObxValue widget that updates the UI based on an observable variable.

    • getdialog: Simplifies dialog creation using GetX.

  • GetX classes:

    • getservice: Generates a GetxService class for services that need to be initialized once.

    • getbinding: Creates a binding class for lazy initialization of controllers and dependencies.

  • Variables:

    • getfinal: Creates a reactive final variable.

    • getset: Generates a setter for a reactive variable.

    • getget: Generates a getter for a reactive variable.

  • GetX one-liners:

    • getput: Initializes a controller and registers it with GetX dependency injection.

    • getlazyPut: Injects a controller lazily.

    • getfind: Retrieves an instance of a registered controller.

    • getoffAllNamed: Removes all routes from the navigation stack and navigates to a new named route.

    • getargs: Retrieves arguments passed to the current route.

    • getStorage: Initializes an instance of GetStorage for local storage.

  • Miscellaneous:

    • getmodel: Generates a model class with JSON serialization methods.

    • gettheme: Creates a ThemeData object defining the app’s theme.

  • Conclusion:

    • GetX Snippets enhances development workflow by reducing boilerplate code.

    • Promotes consistency and best practices, making development more efficient and enjoyable.
