IterableExtensions<E> extension
Methods
-
containsAll(Iterable<E> other)
→ bool
-
Returns true if the specified value is equal to at least one element of the given list;
false otherwise
-
foldWithNext<V>(V initialValue, V combiner(V previousValue, E current, E next))
→ V
-
Reduces a collection to a single value by iteratively combining previous and current
element of the collection with an existing value
-
generateBook({int? valuesPerPage, int? numberOfPages})
→ Map<int, List<E>>
-
-
generateMap<K, V>(MapEntry<K, V> generator(E))
→ Map<K, V>
-
Generate the map by collection.
-
groupBy<K>(K fn(E element))
→ Map<K, List<E>>
-
Splits a list into sub-lists stored in an object, based on the result of calling a
function on each element, and grouping the results according to values returned.
-
joinBy(E generator(int index))
→ Iterable<E>
-
Concatenates the elements given by function.
-
joinElement(E element)
→ Iterable<E>
-
Concatenates the elements.
-
mapWithIndex<T>(T f(E e, int i))
→ Iterable<T>
-
Returns a new lazy Iterable with elements that are created by
calling
f on each element and index of this Iterable in iteration order.
-
replaces(Map<E, E> replacements)
→ Iterable<E>
-
replace the old elements contained in the map with new ones.
-
toMap()
→ Map<int, E>
-
-
tryElementAt(int index)
→ E?
-
-
tryFirstWhere(bool test(E element))
→ E?
-
Returns the first element that satisfies
test otherwise null.
Iterable.firstWhere
-
tryLastWhere(bool test(E element))
→ E?
-
Returns the last element that satisfies
test otherwise null.
Iterable.lastWhere
-
trySingleWhere(bool test(E element))
→ E?
-
Returns the single element that satisfies
test otherwise null.
Iterable.singleWhere
-
whereNotContains(Iterable<E> elements)
→ Iterable<E>
-
Returns a iterable without
elements
-
without(Iterable<E> badElements)
→ Iterable<E>
-
