In pub.dev it's tagged as discontinued. If you really need to use this library, you can use https://pub.dev/packages/another_flushbar which is the same library but it's maintained by another user and updated to support null safety.
I was actually using the built in library but yours seemed more "complete".
I will check out the another_flushbar package.
Thank you I think we can close this thread.

As an alternative, you can use SnackBar class, which is built in Flutter: https://api.flutter.dev/flutter/material/SnackBar-class.html
