Alias for Iterable.every.
builder<T>(T builder(E)) → List<T>: Available on Iterable<E>, provided by the ExtensionIterableE extension
Iterable.map.toList()
containsAll(Iterable<E> other, {bool collapseDuplicates = true}) → bool: Available on Iterable<E>, provided by the ExtensionIterableE extension
Returns true if every element in other also exists in this.
containsAny(Iterable<E> other) → bool: Available on Iterable<E>, provided by the ExtensionIterableE extension
Returns true if this contains at least one element also contained in other.
firstOrNullWhere(bool predicate(E element)) → E?: Available on Iterable<E>, provided by the ExtensionIterableE extension
Returns the first element matching the given predicate, or null if no such element was found.
none(bool test(E element)) → bool: Available on Iterable<E>, provided by the ExtensionIterableE extension
Returns true if no element of this satisfies test.
one(bool test(E element)) → bool: Available on Iterable<E>, provided by the ExtensionIterableE extension
Returns true if there is exactly one element of this which satisfies test.
sum(num addend(E)) → num: Available on Iterable<E>, provided by the ExtensionIterableE extension
