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

3 out of 43 API elements (7.0 %) 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: scroll_app_bar, scroll_app_bar.ScrollAppBar, scroll_app_bar.ScrollAppBar.ScrollAppBar.new, scroll_app_bar.ScrollAppBar.actions, scroll_app_bar.ScrollAppBar.actionsIconTheme.

0/20 points: Compatible with dependency constraint lower bounds

downgrade analysis failed failed with 6 errors:

• CLASS_USED_AS_MIXIN - lib/src/scroll_app_bar.dart:6:48 - The class 'PreferredSizeWidget' can't be used as a mixin because it's neither a mixin class nor a mixin.
• INVALID_ASSIGNMENT - lib/src/scroll_app_bar.dart:140:37 - A value of type 'AppBarThemeData' can't be assigned to a variable of type 'AppBarTheme'.
• UNDEFINED_GETTER - lib/src/scroll_app_bar.dart:143:21 - The getter 'backwardsCompatibility' isn't defined for the type 'AppBarTheme'.

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.
