Koin: ViewModel

Created on 12 May 2019  路  18Comments  路  Source: InsertKoinIO/koin

Koin project used and used version : koin-core version '2.0.0-GA'

Describe the bug

It seem like koin 2.0.x currently does not support viewmodel in androidx (alpha or beta or even stable version 1.0.2) appcompat and viewmodel . Project compile ok but we always receive error No defition of viewmodel found. (same setup works fine with Koin version 1.0.2). Can we have a branch that support the viewmodel on androidx so that we can use Koin 2.0?

P/s We have include the koin-androidx-viewmodel dependency

question check issue

How do you declare your viewModel?

arnaudgiuliani picture arnaudgiuliani on 13 May 2019

bellow is how i declare viewmodel

import org.koin.androidx.viewmodel.ext.koin.viewModel
import org.koin.dsl.module.module

val featureHomeModule = module {
    factory { GetTopUsersUseCase(get()) }
    viewModel { HomeViewModel(get(), get()) }
}

It works with koin 1.0.2

But in koin 2.0.x
I have tried import
import org.koin.androidx.viewmodel.dsl.viewModel
import org.koin.dsl.module

with same viewmodel declaration as above
Project compile ok but when run there is error 'No definition of viewmodel found`

can you update to 2.0.0-GA2?

arnaudgiuliani picture arnaudgiuliani on 13 May 2019

I may be seeing something similar.

Dependency:
implementation "org.koin:koin-androidx-viewmodel:2.0.0-GA"

In my Activity:
import org.koin.androidx.viewmodel.ext.android.viewModel
val aboutViewModel: AboutViewModel by viewModel()

In my ViewModel:
viewModel { AboutViewModel() }

This fails with a compiler error on the by viewModel():
AboutActivity.kt: (37, 43): Unresolved reference. None of the following candidates is applicable because of receiver type mismatch: public inline fun <reified T : ViewModel> LifecycleOwner.viewModel(qualifier: Qualifier? = ..., noinline parameters: ParametersDefinition? /* = (() -> DefinitionParameters)? */ = ...): Lazy<AboutViewModel> defined in org.koin.androidx.viewmodel.ext.android

My activity ultimately extends androidx.appcompat.app.AppCompatActivity. My ViewModel extends androidx.lifecycle.ViewModel.

same here with 2.0.0-GA4

Be sure to see your definitions in the logs. (think to use androidLogger() or printLogger'() at start). If you don't have your definition from here, it's quite weird :/

The DSL import for viewModel keyword is org.koin.androidx.viewmodel.dsl.viewModel

koin-androidx-viewmodel depends on androidx.lifecycle:lifecycle-extensions:2.0.0-rc01. What do you use?

arnaudgiuliani picture arnaudgiuliani on 17 May 2019

Hi i used these 2

val lifecycleViewModel = "androidx.lifecycle:lifecycle-viewmodel-ktx:${Versions.lifecycle}"
    val lifecycleExtensions = "androidx.lifecycle:lifecycle-extensions:${Versions.lifecycle}"

with val lifecycle = "2.2.0-alpha01"

and 

// KOIN
    val koin = "org.koin:koin-android:${Versions.koin}"
    val koinViewModel = "org.koin:koin-androidx-viewmodel:${Versions.koin}"

with val koin = "2.0.0-rc-3"

NoBeanDefFoundException - you are not starting/loading any module with this definition. Your App.kt file should look more something like:

startKoin {
            androidLogger()
            androidContext(this@App)
            // load modules here
            modules(provideComponent())
        }

the modules() function was missing, and then you don't load anything

Thanks. works like a charm. i forgot to put modules() when migrate from 1.0 to 2.0. can close the issue.
