Properties
-
first
→ Flag<
T> -
The first element.
no setterinherited
- hashCode → int
-
The hash code for this object.
no setteroverride
- isEmpty → bool
-
Whether this collection has no elements.
no setterinherited
- isNotEmpty → bool
-
Whether this collection has at least one element.
no setterinherited
-
iterator
→ Iterator<
Flag< T> > -
A new
Iterator
that allows iterating the elements of thisIterable
.no setteroverride -
last
→ Flag<
T> -
The last element.

no setterinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited

Methods
-
any(
bool test(Flag< T> 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 -
defaultToString(
) → String - Same as toString, but only called when dart:mirrors is not available.
-
elementAt(
int index) → Flag< T> -
Returns the
index
th element.inherited -
every(
bool test(Flag< T> element)) → bool -
Checks whether every element of this iterable satisfies
test
.inherited -
expand<
T> (Iterable< T> toElements(Flag<T> element)) → Iterable<T> -
Expands each element of this Iterable into zero or more elements.
inherited
-
firstWhere(
bool test(Flag< T> element), {Flag<T> orElse()?}) → Flag<T> -
The first element that satisfies the given predicate
test
.inherited -
fold<
T> (T initialValue, T combine(T previousValue, Flag< T> element)) → T -
Reduces a collection to a single value by iteratively combining each
element of the collection with an existing value
inherited
-
followedBy(
Iterable< Flag< other) → Iterable<T> >Flag< T> > -
Creates the lazy concatenation of this iterable and
other
.inherited -
forEach(
void action(Flag< T> element)) → void -
Invokes
action
on each element of this iterable in iteration order.inherited -
has(
Flag< T> flag) → bool -
Returns
true
if this Flags has theflag
enabled,false
otherwise. -
join(
[String separator = ""]) → String -
Converts each element to a String and concatenates the strings.
inherited
-
lastWhere(
bool test(Flag< T> element), {Flag<T> orElse()?}) → Flag<T> -
The last element that satisfies the given predicate
test
.inherited -
map<
T> (T toElement(Flag< T> 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(
Flag< T> combine(Flag<T> value, Flag<T> element)) → Flag<T> -
Reduces a collection to a single value by iteratively combining elements
of the collection using the provided function.
inherited
-
singleWhere(
bool test(Flag< T> element), {Flag<T> orElse()?}) → Flag<T> -
The single element that satisfies
test
.inherited -
skip(
int count) → Iterable< Flag< T> > -
Creates an Iterable that provides all but the first
count
elements.inherited -
skipWhile(
bool test(Flag< T> value)) → Iterable<Flag< T> > -

Iterable
that skips leading elements whiletest
is satisfied.inherited -
take(
int count) → Iterable< Flag< T> > -
Creates a lazy iterable of the
count
first elements of this iterable.inherited -
takeWhile(
bool test(Flag< T> value)) → Iterable<Flag< T> > -
Creates a lazy iterable of the leading elements satisfying
test
.inherited -
toList(
{bool growable = true}) → List< Flag< T> > -
Creates a List containing the elements of this Iterable.
inherited
-
toSet(
) → Set< Flag< T> > -
Creates a Set containing the same elements as this iterable.
inherited
-
toString(
) → String -
A string representation of this object.
inherited
-
where(
bool test(Flag< T> element)) → Iterable<Flag< T> > -

predicate
test
.inherited -
whereType<
T> () → Iterable< T> -
