Operators

operator *(int n) → Iterable<E>

Available on Iterable<E>, provided by the HeartIterableOperator extension

Available on Set<E>, provided by the HeartSetOperator extension

Repeat n times. Dart already does this for Strings. 1, 2 * 3 returns 1, 2, 1, 2, 1, 2
operator <(Iterable it) → bool

Available on Iterable<E>, provided by the HeartIterableOperator extension

operator <=(Iterable it) → bool
