Counter Inside AlertDialog - Flutter

flutter custom alert dialog
flutter dialog setstate

I am using an AlertDialog for my application and inside i build an counter. Value of counter does not get updated automatically. i used "setState({})", but it does not help, because it only rebuilds the build() function and not the int _value inside Dialog.

Anyone familiar to this problem and help me out? Thank you

        return AlertDialog(
          title: Text("Title Here"),
          content: Text(contentText),
          actions: <Widget>[

              child: Text("Cancel"),

              onPressed: () {
                setState(() {
                  contentText = "Changed!";
                });
              },
              child: Text("Change Now"),
            ),
          ],
        );
      },
    );
  },

AlertDialog (Flutter Widget of the Week), This video is also subtitled in Chinese, Indonesian, Italian, Japanese, Korean, Portuguese, and Duration: 2:00 Posted: Nov 6, 2019 Flutter simple Alert Dialog Adding simple Dialog to your screen in pretty easy in Flutter. Before adding Dialog you must call showDialog function to change current screen state to show the intermediate Dialog popup. In here we use AlertDialog widget to show simple Dialog with title and some text in the body.

The code sample below solved my problem. As @anmol.majhail nicely referred, a wrote my AlertDialog inside a new class, which was then called by the build() function. To call the class and show AlertDialog i used to do this.

Widget createItem() {
    return new FloatingActionButton(
      elevation: 4.0,
      child: const Icon(Icons.create),
      onPressed: () {
        showDialog(
          context: context,
          child: new ItemAlertView()
        );
      },
    );
  }

This example helped me out (compare to line 59). https://gist.github.com/harshapulikollu/5461844368e95c6d3a38fffe72f03eee
