我无法启动我的应用程序，因为这两个新模块DataStoreModule和UserModule到目前为止我所做的：

interface DataStoresProvider {
    fun userDataStore(): DataStore<Preferences>
}

class UserDataStore(
    dataStoresProvider: DataStoresProvider
) : ModelDataStore<UserModel>(
    dataStoresProvider.userDataStore(),
    USER_KEY
) {

interface UserRepository {

    suspend fun saveUser(userModel: UserModel)

    suspend fun getUser(): Flow<UserModel?>
}

class UserRepositoryImpl @Inject constructor(val userDataStore: UserDataStore): UserRepository {
    override suspend fun saveUser(userModel: UserModel) {
        userDataStore.putModel(userModel)
    }

    override suspend fun getUser(): Flow<UserModel?> {
        return userDataStore.getModel<UserModel>()
    }
}

@HiltViewModel
class HomeViewModel @Inject constructor(val userRepository: UserRepository) : ViewModel() {

@Composable
fun HomeScreen(outputDirectory: File?) {
   val viewModel = hiltViewModel<HomeViewModel>()

或版本，其中包含MainActivity中的ViewModel

@Composable
fun HomeScreen(outputDirectory: File?, viewModel: HomeViewModel) {

@AndroidEntryPoint
class MainActivity : ComponentActivity() {
    private val viewModel: HomeViewModel by viewModels()

模块：

@Module
@InstallIn(SingletonComponent::class)
object DataStoresModule {

    @Provides
    fun provideUserDataStore(dataStoresProvider: DataStoresProvider): UserDataStore {
        return UserDataStore(dataStoresProvider)
    }

}

@Module
@InstallIn(SingletonComponent::class)
class UserModule {

    @Provides
    fun provideUserRepository(userDataStore: UserDataStore): UserRepository {
        return UserRepositoryImpl(userDataStore)
    }
}

我的错误：

error: [Dagger/MissingBinding] com.example.insta.local.DataStoresProvider cannot be provided without an @Provides-annotated method.

型
我不明白为什么它不起作用。每个组件提供另一个直到viewModel。

UserDataStore

class UserDataStore @Inject constructor(
    val dataStoresProvider: DataStoresProvider
) : ModelDataStore<UserModel>(
    dataStoresProvider.userDataStore(),
    USER_KEY
) {

    companion object {
        val USER_KEY = baseStringPreferencesKey("USER_KEY")
    }
}

加入：

@Provides
    fun provideUserDataStoreProvider(@ApplicationContext app: Context): DataStoresProvider {
        return DataStoreProviderImpl(app)
    }

与

class DataStoreProviderImpl @Inject constructor(
    private val context: Context
) : DataStoresProvider {

    private val Context.userDataStore: DataStore<Preferences> by appPreferencesDataStore(
        name = "userData"
    )

    override fun userDataStore(): DataStore<Preferences> {
        return context.userDataStore
    }

}

fun appPreferencesDataStore(name: String) = preferencesDataStore(name = name + DATA_STORE_SUFFIX)

private const val DATA_STORE_SUFFIX = "_v3"```
