I have album detail view witch displays album base...

I have album detail view witch displays album based on Id passed by intent extra to my Activity.
Normally I would inject AlbumDetailsViewModelFactory into Activity, however this time this factory needs additional parameter - id (what is the best way to achieve this? How can we inject this factory into Activity or ViewModel and pass the id?)

Pass the id using the Intent that starts the Activity. Then when creating an instance of your AlbumDetailsViewModel, provide the id by doing intent.getStringExtra

Let’s me be clear: To obtain VievModel with arguments we have to use custom factory (class extending ViewModel.Factory). It would be preferable to inject this factory into activity, however factory requires a bit of configuration (album Id) before it is constructed 🤔

[streetsofboston]

That is true. In our app, we created a extension function on an Activity and Fragment, called bindViewModel, that takes a KodeinAware as a second receiver, a lambda as a parameter, and uses a custom ViewModel.Factory for its implementation. The lambda will return a new ViewModel when it is called. This allows for arguments (eg the intent extra) to be provided.

Sounds good @streetsofboston. Can you please share code of these extensions and usage in the Fragment?
