/// @assertion A final variable is a variable whose binding is fixed upon
/// initialization; a final variable v will always refer to the same object
/// after v has been initialized. The declaration of a final variable must
/// include the modifier final.
/// It is a static warning if a final instance variable that has been
/// initialized at its point of declaration  is  also initialized in a
/// constructor.
/// It is a compile-time error if a local variable v is final and v is not
/// initialized at its point of declaration.
///
/// @note With https://github.com/dart-lang/language/pull/1091/files changes, it
/// is not an error to declared a final local variable without an initialized. It
/// is an error to read one unless it is definitely assigned.
///
/// @description Checks that there is no compile error if local variable is final
/// and not initialized at its point of declaration.
