Hey guys when using compose,  viewmodel,  and hilt. What would be the best way to pass an argument from the viewmodel to a repository?  On a click on list the ID of item is passed to the details viewmodel.  But in my repository I need to use that ID to retrieve the recipe

I guess I could call the recipe by its id from firestore directly from the viewmodel (to make it work)  but I would like to call the recipe from the repository using flow.  I feel like there has to be a way using hilt? But I could be wrong.

The repository should be a dependecy of the viewmodel. And after you receive the ID via a click event you pass it to the repository

Ok, so I was on the right track. I have the repository as a dependency already,  how do I go about passing it to the repository? Do I have a variable in the repository and a function that sets the variable? Like repo.setId(recipeId)?

Since repositories are usually singletons that wouldn’t be the best approach.
You should define a function inside the repo that returns what you need:

`fun returnMyData(id: Long): DataDetails`

Besides this approach, you can also define a Flow or some other reactive way of getting your data
