FYI this is what multiple assets section errors looks like from the user's perspective:

Error detected in pubspec.yaml:
Unable to parse assets section.
In flavors section of asset "assets/a.txt": Expected flavors to be a list of String, but got {a: b} (YamlMap).
In transformers section of asset "assets/a.txt": In args section of transformer using package "yo": Expected args to be a list of String, but got {i am: a map} (YamlMap).
Please correct the pubspec.yaml file at /Users/andrewkolos/Desktop/deleteme/pubspec_testing/pubspec.yaml

+  return errors.isEmpty ? (List<T>.from(yamlList), <String>[]) : (null, errors);
+}
+
+(List<T>? result, List<String> errors) _parseNullableList<T>(Object? yamlList, String context, String typeAlias) {


do we need this helper, or could we inline this at the callsites? I find the DRY benefits of this kind of trivial abstraction often not worth the cognitive overhead.

Addressed in remove _parseNullableList and cleanup

Nice! Ship it
