# DefaultStartupStepTags class

A no-op, empty tag collection returned by DefaultStartupStep.

Implements StartupStepTags with an empty iterator, ensuring that no tags are ever recorded or iterated over.

### Example

    final tags = DefaultStartupStepTags();
    print(tags.isEmpty); // true
    for (final tag in tags) {
      print(tag); // never executed
    }

## Methods

any(bool test(StartupStepTag element)) → bool
  Checks whether any element of this iterable satisfies `test`.
  inherited
cast<R>() → Iterable<R>
  A view of this iterable as an iterable of `R` instances.
  inherited
contains(Object? element) → bool
  Whether the collection contains an element equal to `element`.
  inherited
elementAt(int index) → StartupStepTag
  Returns the `index`th element.
  inherited
every(bool test(StartupStepTag element)) → bool
  Checks whether every element of this iterable satisfies `test`.
  inherited
expand<T>(Iterable<T> toElements(StartupStepTag element)) → Iterable<T>
  Expands each element of this Iterable into zero or more elements.
  inherited
firstWhere(bool test(StartupStepTag element), {StartupStepTag orElse()?}) → StartupStepTag
  The first element that satisfies the given predicate `test`.
  inherited
fold<T>(T initialValue, T combine(T previousValue, StartupStepTag element)) → T
  Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
  inherited
followedBy(Iterable<StartupStepTag> other) → Iterable<StartupStepTag>
  Creates the lazy concatenation of this iterable and `other`.
  inherited
forEach(void action(StartupStepTag element)) → void
  Invokes `action` on each element of this iterable in iteration order.
  inherited
join([String separator = ""]) → String
  Converts each element to a String and concatenates the strings.
  inherited
lastWhere(bool test(StartupStepTag element), {StartupStepTag orElse()?}) → StartupStepTag
  The last element that satisfies the given predicate `test`.
  inherited
map<T>(T toElement(StartupStepTag e)) → Iterable<T>
  The current elements of this iterable modified by `toElement`.
  inherited
noSuchMethod(Invocation invocation) → dynamic
  Invoked when a nonexistent method or property is accessed.
  inherited
reduce(StartupStepTag combine(StartupStepTag value, StartupStepTag element)) → StartupStepTag
  Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
  inherited
singleWhere(bool test(StartupStepTag element), {StartupStepTag orElse()?}) → StartupStepTag
  The single element that satisfies `test`.
  inherited
skip(int count) → Iterable<StartupStepTag>
  Creates an Iterable that provides all but the first `count` elements.
  inherited
skipWhile(bool test(StartupStepTag value)) → Iterable<StartupStepTag>
  Creates an `Iterable` that skips leading elements while `test` is satisfied.
  inherited
take(int count) → Iterable<StartupStepTag>
  Creates a lazy iterable of the `count` first elements of this iterable.
  inherited
takeWhile(bool test(StartupStepTag value)) → Iterable<StartupStepTag>
  Creates a lazy iterable of the leading elements satisfying `test`.
  inherited
toList({bool growable = true}) → List<StartupStepTag>
  Creates a List containing the elements of this Iterable.
  inherited
toSet() → Set<StartupStepTag>
  Creates a Set containing the same elements as this iterable.
  inherited
toString() → String
  Returns a string representation of (some of) the elements of `this`.
  inherited
where(bool test(StartupStepTag element)) → Iterable<StartupStepTag>
  Creates a new lazy Iterable with all elements that satisfy the predicate `test`.
  inherited
whereType<T>() → Iterable<T>
  Creates a new lazy Iterable with all elements that have type `T`.
