Calling inject() extension within @Composable functions

Playing around with Koin + Jetpack Compose, I would like to inject a dependency within a @Composable function.

@Composable
fun AppContent() {
    val newsRepository: NewsRepository by inject() // <~ it does not copile
    NewsScreen(newsRepository)
}

In this case, you get an error, because inject is an extension on KoinComponent, and there is no KoinComponent in this scope.

So, I thought about a @Composable function that provides a KoinComponent scope.

object InjectableComponent : KoinComponent

@Composable
fun Injectable(child: @Composable InjectableComponent.() -> Unit) {
   child(InjectableComponent)
}

Using this @Composable would be like this:

@Composable
fun AppContent() {
    Injectable { 
        val newsRepository: NewsRepository by inject()
        NewsScreen(newsRepository)
    }
}

I’d like to discuss this topic and hear opinions from you all

KoinContextHandler is the context handler, that help us prepare the land for Kotlin MP & otehr Koin context handling strategies. GlobalContext is not accessible anymore I guess 🤔

We have started to speak about a compose project for Koin on #koin-dev
