从数据模块注入时无法创建视图模型类。 我有这个模块层
app -> feature -> data@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()
}
}
创建视图模型
@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)
}
}
当我启动因以下错误而崩溃的应用程序时： 无法创建 com.example.auth_feature.presentation.SignUpViewModel 类的实例
尝试创建没有接口的特定@provides，但不幸的是即使这样也没有帮助
完整的崩溃日志：
