Dependency Injection in Flutter using GetIt

Dependency injection is a software design pattern that allows objects to obtain their dependencies from an external source rather than creating them internally. This approach decouples the classes and promotes loose coupling, making the code more modular, reusable, and testable.

Now GET IT will help us in Flutter

GetIt is a powerful service locator and dependency injection container for Flutter. It provides a straightforward API for registering and retrieving instances of objects across the application.

We normally use three registering service:

1. Register Singleton: Method is typically called during the initialisation phase of the application, such as in the main() function. By registering a dependency as a singleton, you ensure that the same instance is shared across the entire application, reducing resource usage and maintaining consistency.
2. Register Lazy Singleton: You to create an instance of a dependency only when it is first accessed. When the…
