Dependency injection is a powerful concept that enhances the maintainability and testability of Android applications. With the combination of Dagger Hilt and Jetpack Compose, you can build robust and efficient apps while minimizing boilerplate code. In this article, we’ll explore how to leverage Dagger Hilt in a Jetpack Compose-based Android app.

Introducing Dagger Hilt and Jetpack Compose

Dagger Hilt: Dagger Hilt is a dependency injection framework tailored for Android development. It simplifies dependency injection setup and usage by providing annotations and integrating seamlessly with Android components.

Jetpack Compose: Jetpack Compose is a modern UI toolkit for building native user interfaces in a declarative manner.

Benefits of Using Dagger Hilt

  1. Reduced Boilerplate: Dagger Hilt reduces the amount of boilerplate code needed for dependency injection, while Jetpack Compose simplifies UI development.
  2. Annotation-Based: Both Dagger Hilt and Jetpack Compose heavily rely on annotations, resulting in cleaner and more readable code.
  3. Standardized Architecture: Dagger Hilt enforces a standardized architecture by integrating well with Android components, and Jetpack Compose promotes a unidirectional data flow.
  4. Seamless Integration: Both libraries integrate seamlessly with each other, enabling smooth development of feature-rich and maintainable apps.

Getting Started

Let’s dive into a practical example of using Dagger Hilt and Jetpack Compose in an Android app.

Step 1: Add Dependencies

In your app’s build.gradle file, include the necessary dependencies:

dependencies {
implementation "com.google.dagger:hilt-android:2.38.1"
kapt "com.google.dagger:hilt-compiler:2.38.1"
implementation "androidx.hilt:hilt-lifecycle-viewmodel:1.0.0-alpha03"
kapt…
