Can you explain what the Dependency Injection pattern is in the context of Scout?

The Dependency Injection pattern in the context of Scout (an Android framework) is used to simplify dependency management between application components. Instead of creating objects directly within a class, dependencies are passed from outside, usually through constructors or setters.

This allows:

• Simplifying testing by substituting mocks or stubs.
• Increasing modularity and flexibility of the code.
• Centralizing dependency configuration.

In Scout, DI can be implemented through special annotations or through containers that automatically create and provide the necessary objects to components.

Example in Kotlin:

class UserRepository @Inject constructor(private val apiService: ApiService) {
    // Uses apiService, which is injected from outside
}
