title: Replace dismissed widget with new widget in Flutter
body: <p>I am getting an error with my current implementation of my Dismissable widget. It returns the 'Make sure to implement the onDismissed handler and to immediately remove the Dismissable widget' error. The error makes sense to me, but I am trying to reset the state of the widget. I can't figure out how to set the onDismissed property return a new card. I am using the Dismissable widget on a card. And I would like to be able to dismiss the card and automatically replace it with a new one. Is the dismissable widget even the appropriate route I should be taking? Thanks.</p>
