Warns when the last element of an Iterable is accessed by iterable[iterable.length - 1] or iterable.elementAt(iterable.length - 1) instead of calling iterable.last.

Example​

❌ Bad:

const list = [1, 2, 3, 4, 5, 6, 7, 8, 9];

list.elementAt(list.length - 1); // LINT: Prefer '.last' instead of accessing the last element by index.
list[list.length - 1]; // LINT: Prefer '.last' instead of accessing the last element by index.

✅ Good:

const list = [1, 2, 3, 4, 5, 6, 7, 8, 9];

list.last;
