Mastering
Callbacks within #FlutterFlow components can be extremely handy by executing actions, which are defined on your parent page, once the action within a component has completed.
In this simple walkthrough video I will show you 3 basic examples where callbacks have been setup. One really common usecase for a callback from a component is when you perhaps need to refresh the ListView on a page once an action has completed within the component itself. I'll show you an example of doing this using a #Supabase example.
By end of this video you will see how Callbacks are setup ready to use in your own projects.
