I'm getting this message whenever I try to use `super.param` the same way I use `this.param` in a constructor. It's a relatively new feature in Dart. – Aknahseh_tg May 11 '22 at 19:58

super-parameters were added in Dart 2.17.0.
If you're not already using the latest version, run
flutter upgrade
To use super-parameters in your app, open your pubspec.yaml file and update sdk to target min 2.17.0:
environment:
sdk: ">=2.17.0 <3.0.0"

1I'm having same issue. Running Dart 2.18.6, did ```flutter upgrade``` and ```flutter pub get``` afterwards. same thing. Any idea what else could be wrong? – Bashar Abdullah Dec 26 '22 at 20:54

Also, if you have
environment:
sdk: ">=2.17.0 <3.0.0"
and you still have an error, try to upgrade you dependencies:
flutter packages upgrade
