Multiple toasts overlap

[muezz]

Describe the bug When multiple toasts are triggered, they animate over each other.

To Reproduce Steps to reproduce the behavior:

1. Trigger a showCustomNotification. Use the code below:

void botToast() {
    BotToast.showCustomNotification(
      align: Alignment.bottomCenter,
      enableSlideOff: true,
      onlyOne: false,
      crossPage: true,
      animationDuration: _toastDuration,
      animationReverseDuration: _toastDuration,
      backButtonBehavior: BackButtonBehavior.ignore,
      dismissDirections: [DismissDirection.down, DismissDirection.horizontal],
      duration: _autoCloseDuration,
      toastBuilder: (cancelFunc) {
        return _CoreToastV2.generic(
          cancel: cancelFunc,
          message:
              'Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old',
        );
      },
      wrapToastAnimation: (controller, cancelFunc, widget) {
        return SizeTransition(
          sizeFactor: controller,
          axis: Axis.horizontal,
          fixedCrossAxisSizeFactor: 1,
          child: widget,
        );
      },
    );
  }

2. Trigger it multiple times.

Expected behavior I would prefer to have a the ability to customize this behavior.
