dartx 0.8.0

Superpowers for Dart. Collection of useful static extension methods.

0.8.0

• PR-136 New: Multiple extensions for Map. all(), any(), count(), filter(), filterKeys(), filterNot, filterValues, getOrElse(), mapEntries(), mapKeys(), mapValues(), maxBy(), maxWith(), minBy(), minWith, none(), toList(), toMap(), orEmpty()
• PR-127 Improve: sumBy is now generic and works equally for num/int/double
• PR-131 Fix: min()/max() which returned the wrong item for reversed ordered lists
• PR-133 New: plus()/minus() and plusOrNull/minusOrNull to num which handle null
• PR-138 Improve: Iterable.second returns T instead of T?. Analog to first
• PR-142 Fix: isUpperCase/isLowerCase now threat only [a-zA-Z] chars as being uppercase

Also, all linting issues have been fixed and the README has been drastically improved. Thanks @minhqdao

0.7.1

• PR-126 Improve runtime of elementAtOrNull for List
• PR-125 Fix whereNotNull to actually return non-null elements

0.7.0

• All extensions methods now have their own extension which can be imported explicitly with show/hide. This allows the usage of package:collection and dartx in the same file.
• Undeprecate firstOrNullWhere until dartx can export package:collection itself
• New Directory.file and Directory.directory extensions to quickly create file/directory references
• Update time package

0.6.0

• PR-120 Migrate to nullsafety
• Fix minBy, maxBy NPE for empty lists
• PR-69 New Dictionary.contains
• PR-57 New Iterable.slice

0.5.0

• PR-94 Breaking: Iterable<T>.zip(other, transform) now support zipping iterables of other types the T. This is a breaking change because it is now required to add types in the transform function.

  final amounts = [2, 3, 4];
  final animals = ['dogs', 'birds', 'cats'];
  final all = amounts.zip(animals, (int amount, String animal) => '$amount $animal');
  // lambda types are now required:  ⇧           ⇧
  // all: ['2 dogs', '3 birds', '4 cats']
  

• PR-90 New String extensions
  • String removePrefix(String prefix)
  • String removeSuffix(String suffix)
  • String removeSurrounding({String prefix, String suffix})

  final name = 'James Bond'.removePrefix('James '); // Bond
  final milliseconds = '100ms'.removeSuffix('ms'); // 100
  final text = '<p>Some HTML</p>'.removeSurrounding(prefix: '<p>', suffix: '</p>'); // Some HTML
  

• PR-88 New List extension void swap(int, int) which swaps the elements in the indices provided.

  final list = [1, 2, 3, 4];
  list.swap(0, 2); // [3, 2, 1, 4]
  

• PR-100 Relax the upper version constraint of collection to support Flutter 1.20 (which uses collection: 1.3.0-nullsafety)
• PR-101 Relax the upper version constraint of crypto

0.4.2

• Increase dependency range of characters to include 1.0.0
• Raise min sdk version to 2.6.0 to prevent pub publishing warning for pre-release versions

0.4.1

• PR-84 Increase path version range to be compatible with Flutter 1.17
• PR-83 Run tests on macOS

0.4.0

Iterable

• PR-41 New Iterable<T>.containsAny(Iterable<T>) extension
• PR-46 New Iterable<num>.median() extension
• PR-53 New Iterable<T>.asStream() extension converts any Iterable to a Stream
• PR-59 New Iterable<T>.cached extension creates a cached Iterable preventing lazy operators such as .map to execute again
• PR-56 Make Iterable<Iterable<T>>.flatten() typesafe and return Iterable<T> instead of Iterable<dynamic>
• PR-62 New Iterable<T>.chunkWhile(bool Function(T, T) predicate): Iterable<List<E>> extension splits a collection into a lazy Iterables of chunks, where chunks are created as long as predicate is true for a pair of entries.
• PR-62 New Iterable<T>.splitWhen(bool Function(E, E) predicate): Iterable<List<E>> extension splits a collection into a lazy Iterable, where each split will be make if predicate returns true for a pair of entries.
• PR-54 New Iterable<Future<T>>.asStreamAwaited(): Stream<T> extension to create a stream from a group of futures.

String

• PR-72 New String.isNullOrEmpty extension
• PR-43 New String.toInt({int radix}) extension as alias for int.parse(String, {int radix}) (also String.toIntOrNull({int radix}))
• PR-75 Deprecate String.chars in favour of String.characters from the official characters package.

Ranges

• PR-74 New Comparable<T>.rangeTo(Comparable<T> end) extension to create ranges of DateTime or String.
• PR-45 New num.between(num first, num endInclusive): bool extension
• PR-45 New num.inRange(Range<num> range): bool extension
• PR-45 New Comparable<T>.between(T first, T endInclusive): bool extension
• PR-45 New Comparable<T>.inRange(ComparableRange<T> range): bool extension
