Question

I am new in Flutter. I face a problem about _AssertionError ('package:flutter/src/widgets/navigator.dart': Failed assertion: line 4893 pos 12: ':_debugLocked'. is not true.) . I've been looking for a way to fix this for a long time, but I still can't find a solution.

I would be very grateful for any user help.

Answer 1

Just add this to your code:

Future.delayed(Duration.zero, () {
  Navigator.pop(context);
});

Hope this helps you!

Answer 2

Future.delayed(const Duration(milliseconds: 10),
                                    () {
                                  Navigator.of(context, rootNavigator: true)
                                      .pop();
                                });
