How to Dismiss Dialog In Flutter?

To Dismiss Dialog user needs to make use of an inbuilt class like showDialog.

The dialog route created by this method is pushed to the root navigator.

If the application has multiple Navigator objects.

It may be necessary to call Navigator.of(context, rootNavigator: true).pop(result) to close the dialog rather just Navigator.pop(context, result).

Conser a code snippet like below:

BuildContext dialogContext;
   context: context,
   barrierDismissible: false,
   builder: (BuildContext context) {
     dialogContext = context;
     return Dialog(
       child: new Row(
         mainAxisSize: MainAxisSize.min,
         children: [
           new CircularProgressIndicator(),
           new Text("Loading"),

 await _longOperation();

If you don’t want to return any result after showDialog is closed, you can use it.


If you want to pass the result call.

Navigator.pop(context, result);

An example will have a code snippet like the below:

    context: context,
    builder: (_) {
      return AlertDialog(
        title: Text('Wanna Exit?'),
        actions: [
            onPressed: () => Navigator.pop(context, false), // passing false
            child: Text('No'),
            onPressed: () => Navigator.pop(context, true), // passing true
            child: Text('Yes'),
    }).then((exit) {
  if (exit == null) return;

  if (exit) {
    // user pressed Yes button
  } else {
    // user pressed No button

The below code will close AlertBox/DialogBox in Flutter.
