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
, andtheme
subfolders.dal
: Organized intodaos
(Data access objects) andservices
. 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) orget 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
orget 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 aFloatingActionButton
with default settings.getbutton
: Creates aMaterialButton
with a predefined style and anonPressed
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 aGetxService
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 ofGetStorage
for local storage.
Miscellaneous:
getmodel
: Generates a model class with JSON serialization methods.gettheme
: Creates aThemeData
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.
