To reproduce run dart pub outdated --no-dev-dependencies --up-to-date --no-dependency-overrides.

The constraint `^0.2.2` on firebase_vertexai does not support the stable version `1.0.0`.

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

The constraint `0.3.6` on langchain_core does not support the stable version `0.3.6+1`, that was published 3 days ago.

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

Try running dart pub upgrade --major-versions langchain_core 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.

Analyzed with Pana 0.22.17, Dart 3.6.0.
