问如何使用ViewModel在片段之间传递数据？

EN

class HomeFragment : Fragment() {
               private val homeViewModel by viewModel<HomeViewModel>()

               //when user select post I set that value to LeadViewModel (I want to make that viewModel as common for some fragment)
               leadViewModel.state.selectedPost.value = action.post
}


class PostDetailsFragment : Fragment() {
        private val leadViewModel by sharedViewModel<LeadViewModel>()
    
        //always null
        val post = leadViewModel.state.selectedPost.value
}

    viewModel { LeadViewModel() }
    viewModel { HomeViewModel(get(bottomNavigationCommander), get()) }
    viewModel { AddPostViewModel() }
