Flutter : How to hide AlertDialog - flutter

Question

I have a dialog as below :
showDialog(
context: context,
barrierDismissible : true,
useRootNavigator: true,
builder: (BuildContext context) {
return new AlertDialog(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(5.0))),
title: new Flex(
direction: Axis.horizontal,
children: <Widget>[
new CircularProgressIndicator(),
new Padding(
padding: EdgeInsets.only(left: 20.0),
child: new Text("Loading...", style: new TextStyle(
fontSize: 14.0,
color: Colors.black54,
fontFamily: "GoogleSans",
fontWeight: FontWeight.w400
), textAlign: TextAlign.left),
)
],
),
);
},
);
and try to dismiss it with function :
Navigator.of(context, rootNavigator: true).pop();
when in the process of developing, the navigator function it runs well and closes the dialog as expected. but when I upload the application in the google play store, and run the application through the google play store, the navigator function actually closes the application instead of closing the dialog. Why did it happen? is there something wrong with my code ?
and this my flutter doctor -v

Answer 1

Instead of using Navigator.of(context, rootNavigator: true).pop(); use Navigator.of(context).pop();
This should solve the issue. Using Navigator.of(context, rootNavigator: true).pop(); is only necessary if you have multiple Navigator objects in your application.
Otherwise, rootNavigator: True need not be declared.

Answer 2

Try changing useRootNavigator: false, and dismiss your dialog by calling Navigator.of(context).pop()
