• Switched from toCamelCase(attribute.key) to attribute.key in type definitions, constructors, serializers, and accessors
• Applied the change consistently to TypeScript, Swift, PHP, Kotlin, JavaScript, Java, and Dart templates

• The template loop uses attr as the iterator but references attribute.key, which is undefined. It should reference attr.key or update the loop variable to match.

Objects.equals(<%- attribute.key %>, that.<%- attribute.key %>)

• Inside the map callback, attribute.key is undefined because the iterator is named attr. It should use attr.key.

return Objects.hash(<%- collection.attributes.map(attr => attribute.key).join(', ') %>);

• Within the Java toString generation loop, attribute.key is not defined (the loop variable is attribute or attr). Ensure the template uses the correct loop variable name.

"<%- attribute.key %>=" + <%- attribute.key %> +
