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
asNameMap() → Map<String, T>

Available on Iterable<T>, provided by the EnumByName extension

Creates a map from the names of enum values to the values.
byName(String name) → T

Available on Iterable<T>, provided by the EnumByName extension

Finds the enum value in this list with name name.
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) → dynamic
Returns the indexth element.
inherited
elementAtOrNull(int index) → T?

Available on Iterable<T>, provided by the IterableExtensions extension

The element at position index of this iterable, or null.
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
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
Creates 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
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 nonexistent 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
The single element that satisfies test.
inherited
skip(int count) → Iterable
Creates an Iterable that provides all but the first count elements.
inherited
skipWhile(bool test(dynamic value)) → Iterable

inherited
take(int count) → Iterable
Creates a lazy iterable of the count first elements of this iterable.
inherited
takeWhile(bool test(dynamic value)) → Iterable
Creates 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

inherited
toString() → String
A string representation of this object.
inherited
where(bool test(dynamic element)) → Iterable
