What is the purpose of using the Binds annotation in Dagger for dependency injection?

The @Binds annotation in Dagger is used to bind an interface to its implementation without the need to write a factory method manually. It allows specifying that when a dependency of the interface is requested, a specific class implementing that interface should be provided.

Advantages of @Binds:

• Compactness: no need to write the method body, just declare an abstract method.
• Improved readability and maintainability of the code.
• Allows Dagger to generate more efficient code.

Example:

@Module
abstract class NetworkModule {
    @Binds
    abstract ApiService bindApiService(ApiServiceImpl impl);
}

Here, ApiServiceImpl will be used when injecting ApiService.
