This package is last updated in 2019, I don't think there will be an immediate update. There are only 15 lines of code in here. I'm just gonna create a new mixin with that code, for now at least!

If you would kindly tell me how to do that? or if you made a fork would you pass me the git? i'm new to flutter and i use this mixin, thanks!

Since this is a very simple single file package, I created a new file called 'after_layout_mixin.dart' in my project, and copy pasted the code from here -> https://github.com/fluttercommunity/flutter_after_layout/blob/53abdd3205ad8c9d275a38b02914041bc8c340d6/lib/after_layout.dart

Remove this package from pubspec & import your own mixin instead. When migrating to null safety using the migrate tool, Flutter will automatically add nullsafety to your new mixin.

Note: this is not a good thing to do if the package is a big & complex one, but since this package is only 15 lines, you can do that without consequences.
