error: cannot find symbol @dagger.hilt.InstallIn(value = {ApplicationComponent.class})

After upgrading dagger hilt(version: 2.31-alpha) ApplicationComponent.class can not find. What is the alternative for a Component like RoomDatabase?

@Module
@InstallIn(ApplicationComponent::class)
class RoomModule() {
private val DATABASE_NAME = "salat_time"

@Singleton
@Provides
fun provideRoomDatabase(@ApplicationContext appContext: Context) = Room.databaseBuilder(
    appContext,
    AppDatabase::class.java,
    DATABASE_NAME
).createFromAsset("db/$DATABASE_NAME.sqlite").build()

@Singleton
@Provides
fun provideLocalSalatRepository(database: AppDatabase) = LocalSalatRepository(database)

@Singleton
@Provides
fun provideDistrictRepository(database: AppDatabase) = DistrictRepository(database)
}

ApplicationComponent is Deprecated in Dagger Version 2.30
ApplicationComponent removed in Dagger Version 2.31
Alternatively SingletonComponent should be used instead of ApplicationComponent

@Module
@InstallIn(SingletonComponent::class)
class RoomModule() {
   . . .
}

ApplicationComponent is renamed to SingletonComponent

Just import:

import dagger.hilt.components.SingletonComponent

and annotate your module as:

@Module
@InstallIn(SingletonComponent::class)

Because ApplicationComponent is removed in the newer version of daggerHilt and I'm using these dependencies for dagger hilt within app level gradle file:

//Dagger - Hilt
implementation "com.google.dagger:hilt-android:2.31-alpha"
kapt "com.google.dagger:hilt-android-compiler:2.28-alpha"

implementation "androidx.hilt:hilt-lifecycle-viewmodel:1.0.0-alpha03"
kapt "androidx.hilt:hilt-compiler:1.0.0"

In addition to the accepted answer, please be sure to update to the latest hilt version, or else you will be stuck with KaptExecution Error.

Current version ext.hilt_version = '2.33-beta'

If you do not need @InstallIn, you can always disable explicitly.

Alternatively, the check can be disabled at the individual module level by annotating the module with @DisableInstallInCheck.

As mentioned in https://dagger.dev/hilt/flags.html

Like

@DisableInstallInCheck
@Module
class MyAwesomeModule
