DismisAll doesn't work if multiple toasts called at the same time

[amxDusT]

Describe the bug
I'm trying to show only one toast at a time in my application by dismissing all before showing new toasts, but whenever 2 or more toasts get called at around the same time, they all show instead of dismissing.

To Reproduce

toastification
    ..dismissAll(delayForAnimation: false)
    ..show(
      title: const Text('test 1'),
    )
    ..dismissAll(delayForAnimation: false)
    ..show(
      title: const Text('test 2'),
    );

Expected behavior
The first toast ('test 1') should be dismissed

Flutter information:

• OS: iOS, Android
• Flutter Version: 3.22.3
• Toastification Version 2.1.0

Hey @amxDusT

Thanks for opening this issue

what exactly you want to achive here?

To only show one notification?

[amxDusT]

Exactly.
The problem seems to be in the toastification_manager: it has a delay in showing the toast, apparently waiting for the overlay. Though when dismiss/dismissAll is called these delays don't get removed.
The following pull is an attempt to fix that #123

Alright, I got your point

but I'm not sure the best way to solve it is to keep some toast as idle and keep them in a separate list

let me investigate on this and will let you know what's my plan.
