Simplify Dependency Injection with Hilt 🚀

Hilt is a powerful dependency injection library for Android that simplifies injecting dependencies into your application while adhering to best practices. It’s built on top of Dagger, offering a cleaner and more intuitive API, especially for larger projects. Here’s a quick look at its most useful annotations:

1️⃣ @HiltAndroidApp
This marks your application class as the entry point for dependency injection and sets up the base of Hilt in your app.

2️⃣ @AndroidEntryPoint
Used to inject dependencies into Android components like Activities, Fragments, Services, and more. Without this, you can’t use Hilt in these classes.

3️⃣ @Inject
Used to tell Hilt how to provide instances of a class. It’s applied to constructors, fields, or methods.

4️⃣ @Module and @InstallIn
These annotations define a module where you provide dependencies. Use @InstallIn to specify the scope (e.g., SingletonComponent, ActivityComponent).

@Module
@InstallIn(SingletonComponent::class)
object AppModule {
    @Provides
    fun provideRepository(apiService: ApiService): Repository = Repository(apiService)
}

5️⃣ @Provides
Indicates a function that provides an instance of a dependency.

6️⃣ @Singleton
Hilt should create only one instance of the dependency in the specified scope.

Why Use Hilt?

Hilt eliminates boilerplate code, manages lifecycles for scoped components, and integrates seamlessly with Jetpack libraries. Whether you’re building a small app or a large-scale project, it ensures better scalability and maintainability.
