Cannot create a viewmodel class when injecting from a data module.
I have this module layer app -> feature -> data and i want to inject repository into viewModel
@HiltViewModel
class SignUpViewModel @Inject constructor(private val authRepository: AuthRepository) :
ViewModel() {
private val _signUpState = MutableStateFlow(RegistrationState())
val signUpState = _signUpState.asStateFlow()
fun onNameChange(name: String) {
_signUpState.value = _signUpState.value.copy(name = name)
}
fun onEmailChange(email: String) {
_signUpState.value = _signUpState.value.copy(email = email)
}
fun onPasswordChange(password: String) {
_signUpState.value = _signUpState.value.copy(password = password)
}
fun onSignUpClick() {
authRepository.registerUser()
}
}
ViewModel creating
@Composable
fun SignUpScreen() {
SignUpScreen(viewModel = hiltViewModel())
}
@Module
@InstallIn(SingletonComponent::class)
abstract class AuthModule {
@Binds
internal abstract fun bindsAuthRepository(
authRepository: AuthRepositoryImpl,
): AuthRepository
}
@Module
@InstallIn(SingletonComponent::class)
object DataStorageModule {
@Provides
@Singleton
fun provideAuthLocalDataSource(@ApplicationContext context: Context): AuthDataStorage {
return AuthDataStorage(context)
}
}
When i launch application that crash with this error: Cannot create an instance of class com.example.auth_feature.presentation.SignUpViewModel
Tried to create specific @provides with no interface, but unfortunately even that didn't help
Full crash log:
java.lang.RuntimeException: Cannot create an instance of class ru.yangel.auth_feature.presentation.SignUpViewModel
