How does Flutter's architecture support dependency injection, and what are its benefits?

Flutter's architecture supports dependency injection through the 'get_it' package, which facilitates service location. Dependency injection is a design pattern that helps manage the dependencies of an application, making it more modular and testable. The 'get_it' package provides a simple and efficient way to register and retrieve dependencies throughout the app. The benefits of dependency injection include improved code organization, easier testing, and increased flexibility in changing implementations. Understanding how Flutter supports dependency injection is essential for building maintainable and scalable applications.
