0/10 points: Provide a valid pubspec.yaml

5/5 points: Provide a valid README.md

5/5 points: Provide a valid CHANGELOG.md

10/10 points: Use an OSI-approved license

Detected license: MIT.

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

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

• Running dart pub outdated failed with the following output:

Because packagex >=0.0.85 <0.0.86 depends on system_information ^0.0.10 and packagex >=0.0.86 <1.0.1 depends on system_information ^0.0.12, packagex >=0.0.85 <1.0.1 requires system_information ^0.0.10.
And because every version of system_information depends on flutter from sdk, packagex >=0.0.85 <1.0.1 requires flutter from sdk.

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

• Could not run dart pub outdated: dart pub get failed:

And because every version of system_information depends on flutter from sdk, packagex >=0.0.85 <1.0.1 requires flutter from sdk.
So, because flutter from sdk doesn't exist (the Flutter SDK is not available) and whatsapp_client depends on packagex ^0.0.85, version solving failed.

Flutter users should use `flutter pub` instead of `dart pub`.


You can try the following suggestion to make the pubspec resolve:
* Consider downgrading your constraint on packagex: dart pub add packagex:^0.0.0

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

0/20 points: Compatible with dependency constraint lower bounds

Run dart pub downgrade and then dart 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.
