any method Null safety

bool any(
  1. bool test(
    1. E element
    )
)

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.

Example:

final numbers = <int>[1, 2, 3, 5, 6, 7];
var result = numbers.any((element) => element >= 5); // true;
result = numbers.any((element) => element >= 10); // false;

Implementation

bool any(bool test(E element)) {
  for (E element in this) {
    if (test(element)) return true;
  }
  return false;
}
