↳ | androidx.lifecycle.ViewModelStore |
Class to store ViewModels
.
An instance of ViewModelStore
must be retained through configuration changes: if an owner of this ViewModelStore
is destroyed and recreated due to configuration changes, new instance of an owner should still have the same old instance of ViewModelStore
.
If an owner of this ViewModelStore
is destroyed and is not going to be recreated, then it should call clear()
on this ViewModelStore
, so ViewModels
would be notified that they are no longer used.
Use ViewModelStoreOwner#getViewModelStore()
to retrieve a ViewModelStore
for activities and fragments.
