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

This answer works if you want to pop the dialog and navigate to another view. This part 'current_user_location' is the string the router need to know which view to navigate to.

FlatButton(
           child: Text('NO'),
           onPressed: () {
             Navigator.popAndPushNamed(context, 'current_user_location');
              },
           ),

Answer 2

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.

This works Prefectly

      RaisedButton(
                child: Text(
                  "Cancel",
                  style: TextStyle(color: Colors.white),
                ),
                color: Colors.blue,
                onPressed: () => Navigator.pop(context),
              ),

You could wrap your AlertDialog in a async method to make the things clean.

  _showAlertConfirmDelete() async {
    // the response will store the .pop value (it can be any object you want)
    var response = await showDialog(
        context: context,
        builder: (context) => AlertDialog(
              title: Text('Warn'),
              content: Text('Really wants to remove the record?'),
              actions: <Widget>[
                FlatButton(
                    onPressed: () => Navigator.of(context)
                        .pop(false), 
                    child: Text('No')),
                FlatButton(
                    onPressed: () => Navigator.of(context).pop(true),
                    child: Text('Yes'))
              ],
            ));
    // do you want to do with the response.
    print(response);
  }
