-
Creates a SortedMap instance with an optional ordering.
factory
-
SortedMap.from(Map<
K, V> other, [Ordering ordering = const Ordering.byKey()]) -
Creates a SortedMap that contains all key/value pairs of
other
.factory - SortedMap.fromIterable(Iterable iterable, {K key(dynamic)?, V value(dynamic)?, Ordering ordering = const Ordering.byKey()})

Methods
-
addAll(
Map< K, V> other) → void -

other
to this map.inherited -
addEntries(
Iterable< MapEntry< newEntries) → voidK, V> > -
Adds all key/value pairs of
newEntries
to this map.inherited -
cast<
RK, RV> () → Map< RK, RV> -
Provides a view of this map as having
RK
keys andRV
instances, if necessary.inherited -
clear(
) → void -

inherited
-
clone(
) → SortedMap< K, V> - Makes a copy of this map. The key/value pairs in the map are not cloned.
-
containsKey(
Object? key) → bool -
Whether this map contains the given
key
.inherited -
containsValue(
Object? value) → bool -
Whether this map contains the given
value
.inherited -
filteredMap(
{required Pair start, required Pair end, int? limit, bool reversed = false}) → FilteredMap< K, V> - Creates a filtered map based on this map.
-
filteredMapView(
{required Pair start, required Pair end, int? limit, bool reversed = false}) → FilteredMapView< K, V> - Creates a filtered view of this map.
-
firstKeyAfter(
K key, {K orElse()?}) → K -
Get the first key in the map for which the key/value pair is strictly
larger than that of
key
. -
forEach(
void action(K key, V value)) → void -
Applies
action
to each key/value pair of the map.inherited -
lastKeyBefore(
K key, {K orElse()?}) → K -
Get the last key in the map for which the key/value pair is strictly
smaller than that of
key
. -
map<
K2, V2> (MapEntry< K2, V2> convert(K key, V value)) → Map<K2, V2> -
Returns a new map where all entries of this map are transformed by
the given
convert
function.inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
putIfAbsent(
K key, V ifAbsent()) → V -
Look up the value of
key
, or add a new entry if it isn't there.inherited -
remove(
Object? key) → V? -

key
and its associated value, if present, from the map.inherited -
removeWhere(
bool test(K key, V value)) → void -

key
.inherited -
updateAll(
V update(K key, V value)) → void -
