any method

bool any (bool test(E element))

override

Checks whether any element of this iterable satisfies test.

Checks every element in iteration order, and returns true if any of them make test return true, otherwise returns false.

Implementation

bool any(bool test(E element)) {
  int length = this.length;
  for (int i = 0; i < length; i++) {
    if (test(this[i])) return true;
    if (length != this.length) {
      throw ConcurrentModificationError(this);
    }
  }
  return false;
}
