In Flutter applications, managing dependencies efficiently across different screens and flows can become complex, especially when dealing with multiple dependencies that have varying lifecycles.

What is Dependency Injection?

Dependency Injection (DI) is a powerful design pattern that helps separate concerns by decoupling object creation from business logic. It improves code maintainability, scalability, and testability, especially in complex applications.

In Flutter, DI becomes essential for managing services, repositories, and view models that various components of the app depend on. The get_it package is one of the most popular DI solutions for Flutter, providing an easy way to register and resolve dependencies. However, as applications grow, using get_it manually can become cumbersome, leading to a need for more automation and advanced features like scoped dependencies.

This is where the injectable package comes into play, providing automatic code generation and enhanced scope management.
