## Properties

first → String
  Returns the first element. [...]
  read-only, inherited
frozen → bool
  Returns `true` if classes cannot be added or removed from this `CssClassSet`.

hashCode → int
  The hash code for this object. [...]
  read-only, inherited
isEmpty → bool
  Returns `true` if there are no elements in this collection. [...]
  read-only, inherited
isNotEmpty → bool
  Returns true if there is at least one element in this collection. [...]
  read-only, inherited

## Methods

add(String value) → bool
  Add the class `value` to element. [...]
  override
addAll(Iterable<String> iterable) → void
  Add all classes specified in `iterable` to element. [...]
  override
any(bool test(String element)) → bool
  Checks whether any element of this iterable satisfies `test`. [...]
  inherited
cast<R>() → Set<R>
  Provides a view of this set as a set of `R` instances. [...]
  inherited
clear() → void
  Removes all elements in the set.
  inherited
contains(Object? value) → bool
  Determine if this element contains the class `value`. [...]
  override
containsAll(Iterable<Object?> other) → bool
  Returns whether this Set contains all the elements of `other`.
  inherited
difference(Set<Object?> other) → Set<String>
  Returns a new set with the elements of this that are not in `other`. [...]
  inherited
elementAt(int index) → String
  Returns the `index`th element. [...]
  inherited
every(bool test(String element)) → bool

  inherited
expand<T>(Iterable<T> f(String element)) → Iterable<T>

  inherited
firstWhere(bool test(String element), {String orElse()}) → String
  Returns the first element that satisfies the given predicate `test`. [...]
  inherited
fold<T>(T initialValue, T combine(T previousValue, String element)) → T

  inherited
followedBy(Iterable<String> other) → Iterable<String>
  Returns the lazy concatentation of this iterable and `other`. [...]
  inherited

  inherited
map<T>(T f(String e)) → Iterable<T>

  inherited
reduce(String combine(String value, String element)) → String
