Example about how to setup and implement Dagger Hilt in order to understand the basic concepts

Setup

1. build.gradle

   You can check up the last plugin version on Maven

   buildscript {
       ...
       ext.hilt_version = "2.31.2-alpha"
       ...
       repositories {
           // other repositories...
           mavenCentral()
       }
       dependencies {
           // other plugins...
           classpath "com.google.dagger:hilt-android-gradle-plugin:$hilt_version"
       }
   }

2. app/build.gradle

   plugins {
       ...
       id "org.jetbrains.kotlin.kapt"
       id "dagger.hilt.android.plugin"
   }
   
   ...
   
   dependencies {
       ...
       implementation "com.google.dagger:hilt-android:$hilt_version"
       kapt "com.google.dagger:hilt-android-compiler:$hilt_version"
   
       // For instrumentation tests
       androidTestImplementation  "com.google.dagger:hilt-android-testing:$hilt_version"
       kaptAndroidTest "com.google.dagger:hilt-android-compiler:$hilt_version"
   
       // For local unit tests
       testImplementation "com.google.dagger:hilt-android-testing:$hilt_version"
       kaptTest "com.google.dagger:hilt-android-compiler:$hilt_version"
   
       // Activity KTX for viewModels()
       implementation "androidx.activity:activity-ktx:1.2.0"
       ...
   }
   
   kapt {
       correctErrorTypes true
   }

Implementation

1. Application class

   @HiltAndroidApp
   class MyApplication : Application()
