Correct way to handle fragment's flow in the viewModel

Question

I have a Fragment with a ViewModel.

In the Fragment I have a View which exposes a coroutine flow and I want to handle the collection within the ViewModel, and obviously I'm not going to reference the View to the ViewModel.

My idea was basically at the fragment onViewCreated:

view.flow
    .onEach(viewModel::collect)
    .launchIn(viewModel.viewModelScope)

This works, but... is this a good implementation? Or is there a better way to achieve my goal?

Answer 1

I believe you can use a standard fragment's scope not viewmodelScope

viewLifecycleOwner.lifecycleScope from androidx.lifecycle:lifecycle-runtime-ktx:2.2.0 dependency.

like this

view.flow
    .onEach(viewModel::collect)
    .launchIn(viewLifecycleOwner.lifecycleScope)
