fast_immutable_collections: ^7.0.1 copied to clipboard

Const IMap. Example: const IMap<String, int> myMap = IMapConst({1:'a', 2:'b'}); Example of const empty map: const IMap<String, int> myMap = IMapConst({});

Const IMapOfSets. Example: const IMapOfSets<String, int> myMapOfSets = IMapOfSetsConst(IMapConst({})); Example of const empty map of sets: const IMapOfSets<String, int> myMapOfSets = IMapOfSetsConst(IMapConst({'a': ISetConst({1, 2})}));

Breaking change: If you use the IListConst.withConfig() or ISetConst.withConfig() constructors, just remove the .withConfig and it will work. For example: IListConst.withConfig([], ConfigList(isDeepEquals: false)) should become IListConst([], ConfigList(isDeepEquals: false)).

Breaking change: Align head and tail to dart convention as getter like first and last

Introduce the OP typedef.

IList.init Access init part of the list.

IList.inits, IList.tails methods.

IList.splitAt Tuples from original list at specified index.

IList.whereNot Reverse predicate for Where.

Iterable<Tuple2<U, V>>.unzip() extension.

IList.count(Predicate) count positive predicates.

IList.iterate generate IList applying OP multiple times.

IList.iterateWhile generate IList applying OP while Predicate stand.

IList.span Tuple2 will contain the longest consecutive positive predicate then the rest of the list.

IList.tabulate Apply function start at 0 on multiples dimensions.

IList.corresponds Check for correspondence between list and applied function on list.

IList.lengthCompare ISet.lengthCompare Direct size comparison as convenience for composition.

Arity property on Abstract Tuple.

Iterable.restrict() restricts some item to one of those present in this iterable.

Reuse ILists and ISets only if they have the exact same generic type.

Const IList. Example: const IList<int> myList = IListConst([1, 2, 3]); Example of const empty list: const IList<String> myList = IListConst([]);

Const ISet. Example: const ISet<int> mySet = ISetConst({1, 2, 3}); Example of const empty set: const ISet<String> mySet = ISetConst({});

Methods IList.get(), IList.getOrNull() and IList.getAndMap().

Extensions List.get(), List.getOrNull() and List.getAndMap().

Better NNBD for divideListAsMap() and sortedLike().

Better Json serialization for NNBD.

Small IMapOfSets.fromIterable() improvement: added ignore parameter.

Breaking change: Removed empty() constructors from IList and ISet. You can create empty collections using IList() and ISet(), or myIList.clear() and myISet.clear(), or IList.withConfig(const [], myConfig) and ISet.withConfig(const [], myConfig), or const IListConst([]) and const ISetConst({}).

Breaking change: Removed all extensions like isNullOrEmpty and similar. This was a good idea before NNBD, but now if you use this Dart can't infer nullability anymore.

Breaking change. Please, add import "package:collection/collection.dart"; to your project. I have removed a few methods, like Iterable.mapIndexed, because they are now present in the collection package.

Breaking change. Please, add import "package:collection/collection.dart"; to your project. I have removed the following methods because they are now present in the collection package:

• Iterable.firstwhereOrNull
• Iterable.whereNotNull

Breaking change: inRange() of nullable num now returns non-null, and orElse is not optional.

Added Iterable.mapNotNull extension. It's similar to map, but returns Iterable<T>, where T can be a non-nullable type. This is equivalent to map plus cast, but has a better name when you are just using it to solve NNBD problems.

Json serialization support for json_serializable with @JsonSerializable (for IList, ISet, IMap, ListSet, ListSetView).

Renamed extension isNotNullOrZero to isNotNullNotZero.

• Iterable.removeDuplicates was renamed to Iterable.whereNoDuplicates to indicate it returns an Iterable.
• Iterable.removeNulls was renamed to Iterable.whereNotNull to indicate it returns an Iterable.
• List.removeNulls now is a List extension only. It mutates the List, removing nulls.
• List.removeDuplicates now is a List extension only. It mutates the List, removing all duplicates.
• Set.removeNulls now is a Set extension only. It mutates the Set, removing all nulls.
