How to update the Homepage just after the showDialog() is dismissed/disposed? Doesn\'t seem like it has an onDispose() function.

There are two approaches.

1. Use async-await

   bool shouldUpdate = await showDialog(...);
   if (shouldUpdate) {
     setState(() {
       // we should update the UI
     });
   }
   

2. Use then

   showDialog(...).then((shouldUpdate) {
     if (shouldUpdate) {
       setState(() {
         // we should update the UI
       });
     }
   });
