A demonstration about how to inject BindingAdapters with Dagger Hilt.

HiltDataBinding.kt

BindingScoped.kt

@Scope
@Retention(AnnotationRetention.BINARY)
annotation class BindingScoped

-------------------------------------------------------

CustomBindingComponent.kt

@BindingScoped
@DefineComponent(parent = SingletonComponent::class)
interface CustomBindingComponent

-------------------------------------------------------

CustomBindingComponentBuilder.kt

@DefineComponent.Builder
interface CustomBindingComponentBuilder {
    fun build(): CustomBindingComponent
}

-------------------------------------------------------

CustomBindingEntryPoint.kt

@EntryPoint
@BindingScoped
@InstallIn(CustomBindingComponent::class)
interface CustomBindingEntryPoint: DataBindingComponent {

    @BindingScoped
    override fun getImageBindingAdapter(): ImageBindingAdapter
}

-------------------------------------------------------

MyApp.kt

@HiltAndroidApp
class MyApp : Application() {

    @Inject
    lateinit var bindingComponentProvider: Provider<CustomBindingComponentBuilder>

    override fun onCreate() {
        super.onCreate()

        val dataBindingComponent = bindingComponentProvider.get().build()
        val dataBindingEntryPoint = EntryPoints.get(
            dataBindingComponent, CustomBindingEntryPoint::class.java
        )

        DataBindingUtil.setDefaultComponent(dataBindingEntryPoint)
    }
}

Thanks alot. its working now @nuhkoca
