Details

DO use iterable.last instead of iterable[iterable.length - 1] or iterable.elementAt(iterable.length - 1).

Bad

const numbers = [1, 2, 3];

final lastNumber = numbers[numbers.length - 1];
// or
final lastNumber = numbers.elementAt(numbers.length - 1);

Good

const numbers = [1, 2, 3];
final lastNumber = numbers.last;
