如何在 flutter 的对话框外点击它时收听？

Question

Just as the title says. I already set barrierDismissible to false when calling showDialog so that the Dialog is not dismissed when tapping outside of it. I tried wrapping the Dialog in a GestureDetector and listening to onTap but this only listens to when the dialog is tapped and not outside of it.

You can use await-then

 await showDialog(
       //Your Dialog Code
).then((val){
//here to run on dismiss codes 
    Navigator.pop(_context);
});
