Dismiss before show other flashbar

[boungly]

I wonder if there's any way to dismiss the current flashbar (if it's showing)?

I don't want it to be stacked in each other.

I think you may need to manage it yourself:

FlashController _previousController;

Future<T> toast<T>(BuildContext context, String message) async {
  if (_previousController?.isDisposed == false) _previousController.dismiss();
  _previousController = FlashController<T>(
    context,
    (context, controller) {
      return Flash.dialog(
        controller: controller,
        alignment: const Alignment(0, 0.5),
        margin: const EdgeInsets.symmetric(horizontal: 16.0, vertical: 8.0),
        borderRadius: const BorderRadius.all(Radius.circular(8.0)),
        enableDrag: false,
        backgroundColor: Colors.black87,
        child: DefaultTextStyle(
          style: const TextStyle(fontSize: 16.0, color: Colors.white),
          child: Padding(
            padding:
                const EdgeInsets.symmetric(horizontal: 16.0, vertical: 8.0),
            child: Text(message),
          ),
        ),
      );
    },
    duration: const Duration(seconds: 3),
  );
  return _previousController.show();
}

@sososdk: Thank a lot for this code. It's working now.

Is there a way to make the flashbar fade in and out but across all screens, not just one screen? I used fade transition widget on the flashbar but its only fading on one screen (the screen that it is applied to)

To check flashbar is dismissed you need to use slightly different way now:

if (_previousController?.controller.isDismissed == false) _previousController?.dismiss();
