fast_immutable_collections 5.0.4

Immutable lists, sets, maps, and multimaps, which are as fast as their native mutable counterparts. Extension methods and comparators for native Dart collections.

[5.0.4] - 2021/06/24

• Introduce the Predicate typedef.

[5.0.2] - 2021/06/23

• List.sortReversed() extension.

[5.0.1] - 2021/05/24

• 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.

[5.0.0] - 2021/05/24

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

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

[4.0.6] - 2021/04/20

• Extension List.withNullsRemoved().

[4.0.5] - 2021/04/19

• The contains() methods now accept null.
• Method toggle() now returns the correct bool.

[4.0.4] - 2021/04/18

• Iterable.isFirst, isNotFirst, isLast and isNotLast.

[4.0.3] - 2021/04/16

• 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.

[3.0.2] - 2021/04/14

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

• Renamed extension isNotNullOrZero to isNotNullNotZero.

[2.0.4] - 2021/04/12

• Factories IList<T>.orNull(), ISet<T>.orNull(), IMap<K, V>.orNull(), and IMapofSets<K, V>.orNull(), that help implement copyWith methods.

[2.0.2] - 2021/20/03

• Breaking changes:
  • 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.

[2.0.1] - 2021/03/03

• Nullsafety improvements.
• isNotNullOrEmpty getter renamed to isNotNullNotEmpty.
• isEmptyButNotNull getter to isEmptyNotNull.

[1.0.28] - 2021/02/09

• More efficient Iterable.sortedLike() and List.sortLike() extensions.
• Set.diffAndIntersect(), Iterable.everyIs() and Iterable.anyIs() extensions.

[1.0.26] - 2021/01/28

• Better generics compatibility for equalItemsAndConfig.

[1.0.18] - 2021/01/19

• IList.replace().
• ISet.difference(), intersection, union now accept iterables.

[1.0.10] - 2021/01/18

• areSameImmutableCollection() and areImmutableCollectionsWithEqualItems() functions.

[1.0.9] - 2021/01/12

• Initial version.
