Answer 1

as per your source code you use https://pub.dev/packages/progress_dialog package for display progress dialog. so as per this package for dismiss dialog you need to use the below method.

pr.hide().then((isHidden) {
  print(isHidden);
});

// or

await pr.hide();

So replace pr.dismiss() with the above method.
