[Official News] Dart: Breaking change 44072: Apps must declare an SDK constraint in pubspec.yaml

[NewsBot]

A new Dart blog post/announcement has been posted!

We’re making a breaking change where dart pub get/flutter pub get/pub get will start to throw an error when resolving a pubspec.yaml file for an app, if the pubspec doesn’t contain a Dart SDK constraint. Most pubspec.yaml files already contain such a constraint, so the expected impact is small.
