0/10 points: 20% or more of the public API has dartdoc comments

Dependency resolution failed, unable to run dartdoc.

10/10 points: Package has an example

0/20 points: Platform support detection failed

0/0 points: WASM compatibility

Unable to detect compatibility with runtime wasm, and this package will not be rewarded full points in a future version of the scoring model.

See https://dart.dev/web/wasm for details.

0/50 points: code has no errors, warnings, lints, or formatting issues

• Running flutter pub outdated failed with the following output:

Note: intl is pinned to version 0.19.0 by flutter_localizations from the flutter SDK.
See https://dart.dev/go/sdk-version-pinning for details.

0/10 points: All of the package dependencies are supported in the latest version

• Could not run flutter pub outdated: flutter pub get failed:

Because every version of playx_localization depends on flutter_localizations from sdk which depends on intl 0.19.0, every version of playx_localization requires intl 0.19.0.
Because playx_localization <0.0.4 depends on intl ^0.18.0 and playx_localization ^0.0.4 depends on intl ^0.18.1, playx_localization <0.1.0 requires intl ^0.18.0.
Thus, playx_localization <0.1.0 is forbidden.
So, because playx depends on playx_localization ^0.0.1, version solving failed.

You can try the following suggestion to make the pubspec resolve:

Run flutter pub downgrade and then flutter analyze to reproduce the above problem.

You may run dart pub upgrade --tighten to update your dependency constraints, see dart.dev/go/downgrade-testing for details.
