Hi! How do I create different instances of a ViewModel on the same destination?

composable(route = "a") {
    Component1(hiltViewModel())
    Component1(hiltViewModel())
}

When you do you want to use a different view model instance?

[Tin Tran]

I have a composable that have multiple sub component. Each of them is a composable. How the component is arranged is read from a server.

Each component have multiple state so I give each component a view model. It work fine when you have the same component only once. But if I add a component 2 times , both of the view models are the same instance and the later added component affects the component added before it.

Hope I clear things out a bit

I think you're using hilt which I have little experience with.

But ViewModels are one instance. That's there whole point.

I think you're trying to use a viewmodel, which is a singleton, twice and expecting them not to be a singleton.

Thanks. I’m using it the wrong way I guess.

I have a similar situation where i need multiple instances for multiple tabs. I'm not using Android Architecture Components ViewModels in this case, but instead just Pojos. To get them injected via Hilt, use EntryPoints https://developer.android.com/training/dependency-injection/hilt-android#not-supported
The default Hilt ViewModels are always Singletons.
