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• Running dart pub outdated failed with the following output: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 macros >=0.1.3-main.0 depends on _macros from sdk which doesn't exist (could not find package _macros in the Dart SDK), macros >=0.1.3-main.0 is forbidden.
So, because singlet depends on macros ^0.1.3-main.0, version solving failed.

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

• Could not run dart pub outdated: dart pub get failed:

You can try the following suggestion to make the pubspec resolve:
* Consider downgrading your constraint on macros: dart pub add macros:^0.0.1

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.
