Methods

add(dynamic val) bool
Add a Node to Graph
any(bool test(dynamic element)) bool
Checks whether any element of this iterable satisfies test.
inherited
cast<R>() Iterable<R>
Provides 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) → dynamic
Returns the indexth element.
inherited
every(bool test(dynamic element)) bool
Checks whether every element of this iterable satisfies test.
inherited
expand<T>(Iterable<T> toElements(dynamic element)) Iterable<T>
Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(dynamic element), {dynamic orElse()?}) → dynamic
Returns the first element that satisfies the given predicate test.
inherited
flatMap<R>(Iterable<R> f(dynamic item)) Iterable<R>
The flatMap() method first maps each element using a mapping function, then flattens the result into a new array
fold<T>(T initialValue, T combine(T previousValue, dynamic element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable other) Iterable
Returns the lazy concatenation of this iterable and other.
inherited
forEach(void action(dynamic element)) → void
Invokes action on each element of this iterable in iteration order.
inherited
has(dynamic val) bool
Determine if there is such a node in graph
join([String separator = ""]) String
Converts each element to a String and concatenates the strings.
inherited
lastWhere(bool test(dynamic element), {dynamic orElse()?}) → dynamic
Returns the last element that satisfies the given predicate test.
inherited
map<T>(T toElement(dynamic e)) Iterable<T>
The current elements of this iterable modified by toElement.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
inherited
reduce(dynamic combine(dynamic value, dynamic element)) → dynamic
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
inherited
remove(dynamic val) bool
If there is such a node, remove it
singleWhere(bool test(dynamic element), {dynamic orElse()?}) → dynamic
Returns the single element that satisfies test.
inherited
skip(int count) Iterable
Returns an Iterable that provides all but the first count elements.
inherited
skipWhile(bool test(dynamic value)) Iterable
Returns an Iterable that skips leading elements while test is satisfied.
inherited
take(int count) Iterable
Returns a lazy iterable of the count first elements of this iterable.
inherited
takeWhile(bool test(dynamic value)) Iterable
Returns a lazy iterable of the leading elements satisfying test.
inherited
toList({bool growable = true}) List
Creates a List containing the elements of this Iterable.
inherited
toSet() Set
Creates a Set containing the same elements as this iterable.
inherited
toString() String
A string representation of this object.
inherited
where(bool test(dynamic element)) Iterable
Returns a new lazy Iterable with all elements that satisfy the predicate test.
inherited
whereType<T>() Iterable<T>
Returns a new lazy Iterable with all elements that have type T.
