[bug]: showCustomSnackBar doesn’t display

[YJxxx]

Describe the bug

I’m using the example from this repository:
https://github.com/Stacked-Org/services/tree/main/example

When I add a Future.delayed before calling showCustomSnackBar, the snackbar does not appear.

What operating system do you use?

macOS

Steps to reproduce the issue

1.	Clone and run the example project.
2.	Modify the snackbar button like this:

          OutlinedButton(
            onPressed: () async {

              // add delay code
              await Future.delayed(Duration(seconds: 1), () {
                print('Showing blue and yellow snackbar after a delay');
              });

              _snackbarService.showCustomSnackBar(
                variant: SnackbarType.blueAndYellow,
                message: 'Blue and yellow',
                title: 'The message is the message',
                onTap: (_) {
                  print('snackbar tapped');
                },
                mainButtonTitle: 'Undo',
                onMainButtonTapped: () => print('Undo the action!'),
              );
            },
            child: Text(
              'Show Blue and Yellow Snackbar',
            ),
          ),

No response

However, if I click the button once, wait a few seconds, and then click it again, two snackbars appear consecutively.

Could you move that into the viewModel and run it in there instead of in the UI.

Want to make sure it's not an issue with the rebuild process on Flutter.
