Could you be more specific?

[AlexShniperson-INO]

we use your plugin in our project and because it's not null safe yet we can't upgrade to Flutter 2.0

[DennisAlund]

Gotcha... there's a PR for it (#90). But I haven't had time to look into upgrading to 2.0 myself yet.

It's been resolved in PR #90
