fast_immutable_collections 6.0.0

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

[6.0.0] - 2021/09/05

• Breaking change: Note, unless you know what an "async flush mode" is were using it explicitly, this breaking change is not important to you, and you don't need to do anything to upgrade. If you want to know the details, however, keep reading. I have removed the async flush mode. The async flush mode only flushed after the async gap, but since Dart does not allow tail-call-optimization (https://github.com/dart-lang/language/issues/1159) it was not possible to guarantee that very large collections created within the current microtask would not throw a stack-overflow error when reading values from it. The solution to make it work async was to tail-call-optimize by hand, which I played with a little bit. For example, check out the new IMap implementations for operator [] and containsKey(). However, I'd actually would have to do that for each and every method that traverses the data tree, for each collection in FIC. The amount of work was just too much, so I've decided to remove the async flush mode. The sync mode was recommended anyway (which now is the only mode, meaning I have removed any references to it in the docs), so I guess that won't make much of a difference to anyone.

[5.1.3] - 2021/08/31

• FromIListMixin and FromISetMixin improvement to deal with IListConst<Never>.

[5.1.2] - 2021/07/19

• IList.sortReversed().

[5.1.1] - 2021/07/16

• ListMap.unsafeFrom() constructor.

[5.1.0] - 2021/06/25

• 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.

[5.0.5] - 2021/06/27

• MapOfSets.isEmptyForKey() and MapOfSets.isNotEmptyForKey().

[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

• 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.
