Name non-constant identifiers using lowerCamelCaseDRT-W1109

DO name non-constant identifiers using lowerCamelCase.

Class members, top-level definitions, variables, parameters, named parameters and named constructors should capitalize the first letter of each word except the first word, and use no separators.

GOOD:

var item;

HttpRequest httpRequest;

align(clearItems) {
  // ...
}
