I am opening a dialog from another dialog and trying to close the 1st dialog, but it is closing the recent dialog. Similar kind of

CodePudding user response：

Create a separate context and pass the correct context which one you want to close to the Navigator.pop(yourContextThatYouWishToClose)

Navigator.pop(dialogContext);

Here is the example code.

BuildContext dialogContext; // <<----
  showDialog(
    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();
  Navigator.pop(dialogContext);

CodePudding user response：

You need to pass context of the dialog you want to close (parentContext) and call:

Navigator.pop(parentContext); // close parent 
Navigator.pop(context); // close current

What you could do is pop twice in showDialog1 and then await for showDialog1 immediately.
