Iterable<T>

Methods

anyIs(T value) → bool: Available on Iterable<T>, provided by the FicIterableExtension extension
Returns true if any item is equal to value.
asList() → List<T>: Available on Iterable<T>, provided by the FicIterableExtension extension
Returns a List containing the elements of this iterable. If the Iterable is already a List, return the same instance (nothing new is created). Otherwise, create a new List from it. See also: Dart's native toList, which always creates a new list.
asSet() → Set<T>: Available on Iterable<T>, provided by the FicIterableExtension extension
Creates a Set containing the same elements as this iterable. If the Iterable is already a Set, return the same instance (nothing new is created). Otherwise, create a new Set from it. See also: Dart's native toSet, which always creates a new set.
averageBy<N extends num>(N mapper(T element)) → double: Available on Iterable<T>, provided by the FicIterableExtension extension
The arithmetic mean of the elements of a non-empty iterable. The arithmetic mean is the sum of the elements divided by the number of elements. If iterable is empty it returns 0. Examples:
deepEquals(Iterable? other, {bool ignoreOrder = false}) → bool: Available on Iterable<T>, provided by the FicIterableExtension extension
Compare all items, in order or not, according to ignoreOrder, using operator ==. Return true if they are all the same, in the same order.
deepEqualsByIdentity(Iterable? other, {bool ignoreOrder = false}) → bool: Available on Iterable<T>, provided by the FicIterableExtension extension
Return true if they are all the same, in the same order. Compare all items, in order or not, according to ignoreOrder, using identical. Return true if they are all the same, in the same order.
everyIs(T value) → bool: Available on Iterable<T>, provided by the FicIterableExtension extension
Returns true if all items are equal to value.
findDuplicates() → Set<T>: Available on Iterable<T>, provided by the FicIterableExtension extension
Finds duplicates and then returns a Set with the duplicated elements. If there are no duplicates, an empty Set is returned.
intersectsWith(Iterable<T> other) → bool: Available on Iterable<T>, provided by the FicIterableExtension extension
Returns true if this Iterable has any items in common with the other Iterable. This method is as performant as possible, but it will be faster if any of the Iterables is a Set or an ISet.
isFirst(T item) → bool: Available on Iterable<T>, provided by the FicIterableExtension extension
Return true if the given item is the same (by identity) as the first iterable item. If this iterable is empty, always return null. This is useful for non-indexed loops where you need to know when you have the first item. For example:
isLast(T item) → bool: Available on Iterable<T>, provided by the FicIterableExtension extension
Return true if the given item is the same (by identity) as the last iterable item. If this iterable is empty, always return null. This is useful for non-indexed loops where you need to know when you have the last item. For example:
isNotFirst(T item) → bool: Available on Iterable<T>, provided by the FicIterableExtension extension
Return true if the given item is NOT the same (by identity) as the first iterable item. If this iterable is empty, always return null. This is useful for non-indexed loops where you need to know when you don't have the first item. For example:
isNotLast(T item) → bool: Available on Iterable<T>, provided by the FicIterableExtension extension
Return true if the given item is NOT the same (by identity) as the last iterable item. If this iterable is empty, always return null. This is useful for non-indexed loops where you need to know when you don't have the last item. For example:
mapIndexedAndLast<R>(R convert(int index, T item, bool isLast)) → Iterable<R>: Available on Iterable<T>, provided by the FicIterableExtension extension
Maps each element and its index to a new value. This is similar to mapIndexed but also tells you which item is the last.
restrict(T? item, {required T orElse}) → T: Available on Iterable<T>, provided by the FicIterableExtension extension
Restricts some item to one of those present in this iterable.
sortedLike(Iterable ordering) → List<T>: Available on Iterable<T>, provided by the FicIterableExtension extension
Returns a list, sorted according to the order specified by the ordering iterable. Items which don't appear in ordering will be included in the end, in their original order. Items of ordering which are not found in the original list are ignored.
sortedReversed([Comparator<T>? compare]) → List<T>: Available on Iterable<T>, provided by the FicIterableExtension extension
Creates a reversed sorted list of the elements of the iterable.
sumBy<N extends num>(N mapper(T element)) → N: Available on Iterable<T>, provided by the FicIterableExtension extension
The sum of the values returned by the mapper function.
toIList([ConfigList? config]) → IList<T>: Available on Iterable<T>, provided by the FicIterableExtension extension
Creates an immutable list (IList) from the iterable.
toISet([ConfigSet? config]) → ISet<T>: Available on Iterable<T>, provided by the FicIterableExtension extension
Creates an immutable set (ISet) from the iterable.
updateById(Iterable<T> newItems, dynamic id(T item)) → List<T>: Available on Iterable<T>, provided by the FicIterableExtension extension
Returns a new list where newItems are added or updated, by their id (and the id is a function of the item), like so:
whereNoDuplicates({dynamic by(T item)?, bool removeNulls = false}) → Iterable<T>: Available on Iterable<T>, provided by the FicIterableExtension extension
Removes all duplicates, leaving only the distinct items. Optionally, you can provide an by function to compare the items.
