After Update Flutter I Got Message Don't use 'BuildContext's across async gaps. Try rewriting the code to not reference the 'BuildContext'

before I upgraded my flutter version everything went smoothly there was no warning. but after I updated flutter suddenly there was a warning Don’t use ‘BuildContext’s across async gaps.
Try rewriting the code to not reference the ‘BuildContext’.

Here is the problem

ProfileMenuItem(
              iconUrl: 'assets/ic_edit_profile.png',
              title: 'Edit Profile',
              onTap: () async {
                if (await Navigator.pushNamed(context, '/pin') == true) {
                 if(context.mounted) Navigator.pushNamed(context, '/profile-edit');
                }
              },
            ),

And heres my full code

import 'package:bank_sha/ui/widgets/buttons.dart';
import 'package:bank_sha/ui/widgets/profile_menu_item.dart';
import 'package:flutter/material.dart';

class ProfilePage extends StatelessWidget {
  const ProfilePage({super.key});

  @override

    Convert ProfilePage into a StatefulWidget and use if(mounted) to check whether the widget is still mounted.

    Try it this way:

    onTap: () async {
  // Declare navigator instance (or other context using methods/classes)
  // before async method is called to use it later in code
  final navigator = Navigator.of(context);

  // Now use the navigator without the warning
  if (await navigator.pushNamed('/pin') == true) {
    navigator.pushNamed('/profile-edit');
  }
},
