为什么我在Dagger2无法正常工作的情况下在此代码中实现Factory？

Question

我原谅了Kotlin中有关匕首的简单代码，但它在运行时不起作用。有什么问题以及如何更新此代码？

我有一个Notification类，我想执行'runNotification'。

    interface Notifications {

        fun runNotification()
    }

    class NotificationsImpl @Inject constructor(
        private val context: Application
    ) : Notifications {

        override fun runNotification() {
            Log.e("Notifications", "runNotification")
        }
    }

NotificationModule.kt

        @Module
    class NotificationModule {
            @Provides
            @Singleton
            fun providerNotifications(notificationsImpl: NotificationsImpl): Notifications = notificationsImpl
        }

ApplicationComponent.kt

    @Singleton
    @Component(modules = [NotificationModule::class])
    interface ApplicationComponent {

        @Component.Builder
        interface Builder {
            @BindsInstance
            fun application(application: Application): Builder

            @BindsInstance
            fun notificationModule(notificationModule: NotificationModule): Builder

            fun build(): ApplicationComponent
        }

        fun inject(application: Application)
    }

应用程序中的代码

    DaggerApplicationComponent.builder()
                .application(this)
                .notificationModule(NotificationModule())
                .build()
                .inject(this)

代码测试（此代码“通知”返回为NULL）：

class MainActivity : AppCompatActivity() {

    @Inject
    lateinit var notifications: Notifications

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        notifications.updateNotification()
    }
}
