Android share ViewModel between fragment and dialog fragment?

Question

How to share same viewModel between dialog and dialogFragment? I know that viewModel can be shared in activity scope. But it is too big scope for me.

 private val model: SharedViewModel by activityViewModels()

Unfortunately I don't have in a project navigation component.

Answer 1

1. Use childFragmentManager to show DialogFragment

2. Declare shared ViewModel inside Fragment by

private val sharedViewModel: YourViewModel by viewModels()

3. Inside DialogFragment declare ViewModel by

private val sharedViewModel: YourViewModel by viewModels(ownerProducer = { requireParentFragment() })
