How to dismiss an AlertDialog on a FlatButton click?

Question

I have the following AlertDialog.

showDialog(
            context: context,
            child: new AlertDialog(
              title: const Text(\"Lo         


        

Answer 1

The accepted answer states how to dismiss a dialog using the Navigator Class. To dismiss a dialog without using Navigator you can set the onPressed event of the button to the following:

setState((){
  thisAlertDialog = null; 
});

In case the code above is not self-explanatory it is basically setting the Parent AlertDialog of the FlatButton to null, thus dismissing it.
