How to refresh datatable from alertdialog in flutter?-CodePudding

I am trying to use an AlertDialog to add rows to a DataTable through a list of class values. However, the DataTable does not seem to be adding new rows when I add into the list of class values even though I'm doing it inside setState.

CodePudding user response：

You need to wait until the popUp is pop and then setState.

For example:

Future showPopUp()async{
   await showDialog(YourDialogHere());
   setState((){});
}

If it does not work with you, please share your code so it can be debugged in detail.

CodePudding user response：

When you close the popup you can return a value and you can handle this value.

Navigator.pop(context, true);
