ListMapView<K, V> class
A ListMapView lets you view a regular map as if it was a ListMap. At the moment this class is for FIC's internal use only, since a lot of its methods will throw UnsupportedError.

Methods
-
addAll(
Map other) → void -
Adds all key/value pairs of
other
to this map.override -
addEntries(
Iterable< MapEntry> newEntries) → void -
Adds all key/value pairs of
newEntries
to this map.override -
cast<
RK, RV> () → ListMap< RK, RV> -
Provides a view of this map as having
RK
keys andRV
instances, if necessary.override -
clear(
) → void -
Removes all entries from the map.
override
-
containsKey(
covariant K? key) → bool -
Whether this map contains the given
key
.override -
containsValue(
covariant V? value) → bool -
Whether this map contains the given
value
.override -
entry(
K key) → MapEntry< K, V> -
Return the key/value entry for the given
key
, or throws ifkey
is not in the map.override -
entryAt(
int index) → MapEntry< K, V> -
Returns the
index
th entry. Theindex
must be non-negative and less than length. Index zero represents the first entry.override -
entryOrNull(
K key) → MapEntry< K, V> ? -
Return the key/value entry for the given
key
, ornull
ifkey
is not in the map.override -
entryOrNullValue(
K key) → MapEntry< K, V?> -
Return the key/value entry for the given
key
. If thekey
is not in the map, returnMapEntry(key, null)
.override -
forEach(
void f(K key, V value)) → void -
Applies
action
to each key/value pair of the map.override -
get(
covariant K key) → V? -
The value for the given
key
, ornull
ifkey
is not in the map.override -
getOrThrow(
K key) → V -
Returns the value if it exists, otherwise throws a
StateError
.override -
indexOfKey(
K key, [int start = 0]) → int -
The first index of
key
in this list.override -
keyAt(
int index) → K -
Returns the
index
th key. Theindex
must be non-negative and less than length. Index zero represents the first key.override -
map<
K2, V2> (MapEntry< K2, V2> f(K key, V value)) → Map<K2, V2> -
Returns a new map where all entries of this map are transformed by
the given
convert
function.override -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
putIfAbsent(
K key, dynamic ifAbsent()) → V -
Look up the value of
key
, or add a new entry if it isn't there.override -
remove(
Object? key) → V -
Removes
key
and its associated value, if present, from the map.override -
removeWhere(
bool predicate(K key, V value)) → void -
Removes all entries of this map that satisfy the given
test
.override -
shuffle(
[Random? random]) → void -
Shuffles the keys of this map randomly.
override
-
sort(
[int compare(K a, K b)?]) → void -
Sorts the keys of this map.
override
-
toString(
) → String -
A string representation of this object.
inherited
-
update(
K key, dynamic update(V value), {dynamic ifAbsent()?}) → V -
Updates the value for the provided
key
.override -
updateAll(
V? update(K key, V value)) → void -
Updates all values.
override
-
valueAt(
int index) → V -
Returns the
index
th value. Theindex
must be non-negative and less than length. Index zero represents the first value.override
Operators
-
operator ==(
Object other) → bool -
The equality operator.
inherited
-
operator [](
covariant K key) → V? -

key
, ornull
ifkey
is not in the map.override -
operator []=(
K key, V? value) → void -
Replaces the
value
of akey
that already exists in the map. However, if the key is not already present, this will throw an error.override
