To reproduce run dart pub outdated --no-dev-dependencies --up-to-date --no-dependency-overrides.

The constraint `^1.2.0` on code_assets does not support the stable version `2.0.0`, that was published 26 days ago.

When code_assets is 30 days old, this package will no longer be awarded points in this category.

Try running dart pub upgrade --major-versions code_assets to update the constraint.

10/10 points: Package supports latest stable Dart and Flutter SDKs

20/20 points: Compatible with dependency constraint lower bounds

pub downgrade does not expose any static analysis error.
