all method

bool all(
  1. bool predicate(
    1. E element
    )
)

Returns true if all elements in the set satisfy the given predicate.

Example:

final numbers = {2, 4, 6};
final allEven = numbers.all((n) => n.isEven); // true

Implementation

bool all(bool Function(E element) predicate) {
  for (final element in this) {
    if (!predicate(element)) return false;
  }
  return true;
}
