pop/push detection with AutoRouteObserver and navigateTo about auto_route_library

[herna]

Ok after further testing, I can see it's related to a Dialog.

I have a button to display a Dialog like this:

showDialog<bool>(
                context: context,
                builder: (BuildContext context) => AlertDialog(
                actions: <Widget>[
                  FilledButton(
                    onPressed: () async {
                      await context.popRoute();
                      // this is a Riverpod call to delete an item from the database
                      ref
                          .read(installationEditControllerProvider(
                                  widget.installationId)
                              .notifier)
                          .deleteInstallation(widget.installationId);
                    }),
                  child: Text('Delete'),
                ],
              ),
);

And in another part of the widget I detect the Riverpod response after the item is deleted to redirect to another page. At this point, if I just do a context.navigateTo(const InstallationsRoute()); it doesn't work but if I do a small pause like the following, then it works:

Future.delayed(const Duration(milliseconds: 200), () => context.navigateTo(const InstallationsRoute()));
It seems related to the time it takes to close the Dialog. The problem is even if I wait like this await context.popRoute(); it doesn't work, I must put a small delay anyway.

Future<void> doInstallationDeleted(BuildContext context) async {
    await Future(() async {
      // IT WORKS
      // Future.delayed(const Duration(milliseconds: 200),
      //     () => context.navigateTo(const InstallationsRoute()));

      // IT DOESN'T WORK
      // context.navigateTo(const InstallationsRoute());
    });
  }

What's the correct way to deal with showDialog() and auto_route?

Thanks.

I also found this issue; this is because navigateTo is asynchronous !

Hi @tomlezen

So how to deal with it? I realised that and tried to await context.navigateTo(const InstallationsRoute()); but nothing changes

Thanks.

You can try to use：context.popForced

Thanks @tomlezen

This seems to work for the Dialog. Anyways I am also facing some other issues when combining navigateTo() with didPopNext(), I was trying to just invalidate a Riverpod provider in the didPopNext() method to refresh some data but it's not always working the same way so I have to manually call ref.invalidate() before navigateTo() to ensure it works as expected.

Thanks again.
