To reproduce run dart pub outdated --no-dev-dependencies --up-to-date --no-dependency-overrides.

The constraint `^0.2.0` on url_strategy does not support the stable version `0.3.0`.

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

The package has one or more discontinued direct dependencies.

Discontinued packages are no longer maintained, and can end up being a liability.

Consider migrating away from these dependencies:

  • url_strategy.

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