This major update of kt.dart adds 16+ extension methods to KtMap and makes working with maps even easier.

Behavior Changes

The properties KtList.list: List,KtSet.set: Set are now deprecated and KtMap.map: Map was removed. Those properties where used to convert kt.dart collections to dart collections.
Instead use the new KtList.asList(): List, KtSet.asSet(): Set, KtMa.asMap(): Map methods.
The old properties returned copies of the collections.
The new as-methods return views of the original collections and reflect changes of the original data.

This breaking change was necessary because the property KtMap.map: Map<K, V> was conflicting with KtMap.map(MapEntry<K, V> -> R) : KtList<R> to map the entries to items of a KtList.
Read about further details here.

If you have used properties to iterate over the collections using a for-loop you should now always use iter which is available for all kt.dart collections.

for (final element in listOf("a", "b", "c").iter) {
  print(element); 
}
for (final element in setOf("a", "b", "c").iter) {
  print(element); 
}
for (final p in mapFrom({1: "Bulbasaur", 2: "Ivysaur"}).iter) {
  print("${p.key} -> ${p.value}"); 
}

Additions

  • #86 New: KtMap.map Returns a list containing the results of applying the given transform function to each entry in the original map.
  • #86 New: KtMap.iter Access to a Iterable to be used in for-loops
  • #87 New: KtMap.count Returns the number of entries matching the given [predicate] or the number of entries when predicate = null.
  • #89 New: KtMap.minBy Returns the first entry yielding the smallest value of the given function or null if there are no entries.
  • #89 New: KtMap.minWith Returns the first entry having the smallest value according to the provided comparator or null if there are no entries.
  • #89 New: KtMap.maxBy Returns the first entry yielding the largest value of the given function or null if there are no entries.
  • #89 New: KtMap.maxWith Returns the first entry having the largest value according to the provided comparator or null if there are no entries.
  • #90 New: KtMap.toList Returns a KtList containing all key-value pairs.
  • #78 New: KtMap.forEach Performs given action on each key/value pair from this map. thanks @acherkashyn
  • #80 New: KtMap.none Returns true if there is no entries in the map that match the given predicate. thanks @acherkashyn
  • #80 New: KtMap.all Returns true if all entries match the given predicate. thanks @acherkashyn
  • #80 New: KtMap.any Returns true if there is at least one entry that matches the given predicate. thanks @acherkashyn
  • #84 New: KtMap.filterKeys Returns a map containing all key-value pairs with keys matching the given predicate.
  • #84 New: KtMap.filterValues Returns a map containing all key-value pairs with values matching the given predicate.
  • #79 New: KtMap.asMap Returns a read-only dart:core Map
  • #79 New: KtMutableMap.asMap Creates a Map instance that wraps the original KtMap. It acts as a view.
  • #75 New: KtIterable.takeWhile Returns a list containing first elements satisfying the given predicate.
  • #76 New: KtIterable.takeLastWhile Returns a list containing last elements satisfying the given predicate.
  • #73 New: KtList.takeLast, Returns a list containing last n elements.
  • #79 New: KtList.asList Returns a read-only dart:core List
  • #79 New: KtMutableList.asList Creates a List instance that wraps the original KtList. It acts as a view.
  • #79, #91 New: KtSet.asSet Returns a read-only dart:core Set
  • #79 New: KtMutableSet.asSet Creates a Set instance that wraps the original KtSet. It acts as a view.
