I click on a button to create a new form. navigation compose (v2,8.5) redirects me to the screen, the view model inits the state and view state, I fill in and submit and go back to the overview page. I then want to create a another item and click on the same new form button. The screen is loaded but the old state and view state variables are still present, How do I get android to auto unload and clear the viewmodel ? Initially I thought I could do it in the NavGraph but I dont know where to start and don't know if thats even possible.
