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

9 out of 59 API elements (15.3 %) have documentation comments.

Providing good documentation for libraries, classes, functions, and other API elements improves code readability and helps developers find and use your API. Document at least 20% of the public API elements.

To highlight public API members missing documentation consider enabling the public_member_api_docs lint.

Some symbols that are missing documentation: navigation_stack, navigation_stack.NavigationStack, navigation_stack.NavigationStack.NavigationStack.new, navigation_stack.NavigationStack.pop, navigation_stack.NavigationStack.push.

downgrade analysis failed failed with 5 errors:

• CREATION_WITH_NON_TYPE - lib/src/navigation_stack.dart:8:35 - The name 'IListConst' isn't a class.
• UNDEFINED_CLASS - lib/src/router.dart:61:3 - Undefined class 'Tuple2'.

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.
