I want to pass data between 4 screens in compose.

What strategies should I use? I have seen options of using SharedViewmodel, CompositionLocal and Room?

maybe that question will be more suitable for #android-architecture? Or you aren't targeting Android only?

I am building a compose app for android, I am having challenges passing data across different composables.

Would you kindly advise?

it depends on what navigation framework you use. If you opt for the AAC (Android Architecture Components) navigation, then navigation arguments are available in the viewmodel via the SavedStateHandle so that would be an option
