-
The hash code for this object.
no setterinherited

-
Whether any listeners are currently registered.
no setterinherited

no setterinherited
-
iterator
→ Iterator<
MapEntry< String, T> > -
A new
Iterator
that allows iterating the elements of thisIterable
.no setterinherited -
keys
→ Iterable<
String> -
Interface to the keys of the map
no setterinherited
-
last
→ MapEntry<
String, T> -
The last element.

The number of elements in this Iterable.
no setterinherited
- runtimeType → Type
-

no setterinherited
-
single
→ MapEntry<
String, T> -

no setterinherited
Methods
-
add(
T item, {String? key, bool notify = true}) → void -
Adds
item
to the map, extending the length by one.override -
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
any(
bool test(MapEntry< String, T> element)) → bool -
Checks whether any element of this iterable satisfies
test
.inherited -
cast<
R> () → Iterable< R> -
A view of this iterable as an iterable of
R
instances.inherited -
clear(
{bool notify = true}) → void -
Removes all objects from this map; the length of the map becomes zero.
override
-
contains(
Object? element) → bool -
Whether the collection contains an element equal to
element
.inherited -
containsKey(
dynamic key) → bool -
Returns if the element specified byt
key
is in the mapinherited -
deserialize(
dynamic map) → void -
Deserializes a map of items with the help of deserializeItem.
inherited
-
deserializeItem(
dynamic data) → T -
Returns a new
T
from the provided serialized data.inherited -
dispose(
) → void -
Discards any resources used by the object. After this is called, the
object is not in a usable state and should be discarded (calls to
addListener will throw after the object is disposed).
inherited
-
elementAt(
int index) → MapEntry< String, T> -
Returns the
index
th element.inherited -
every(
bool test(MapEntry< String, T> element)) → bool -
Checks whether every element of this iterable satisfies
test
.inherited -
expand<
T> (Iterable< T> toElements(MapEntry<String, T> element)) → Iterable<T> -
Expands each element of this Iterable into zero or more elements.
inherited
-
firstWhere(
bool test(MapEntry< String, T> element), {MapEntry<String, T> orElse()?}) → MapEntry<String, T> -
The first element that satisfies the given predicate
test
.inherited -
fold<
T> (T initialValue, T combine(T previousValue, MapEntry< String, T> element)) → T -
Reduces a collection to a single value by iteratively combining each
element of the collection with an existing value
inherited
-
followedBy(
Iterable< MapEntry< other) → Iterable<String, T> >MapEntry< String, T> > -
Creates the lazy concatenation of this iterable and
other
.inherited -
forceNotify(
) → void - If for some reason one needs to call notifier, they can call forceNotify
-
forEach(
void action(MapEntry< String, T> element)) → void -
Invokes
action
on each element of this iterable in iteration order.inherited -
join(
[String separator = ""]) → String -
Converts each element to a String and concatenates the strings.
inherited
-
lastWhere(
bool test(MapEntry< String, T> element), {MapEntry<String, T> orElse()?}) → MapEntry<String, T> -
The last element that satisfies the given predicate
test
.inherited -
map<
T> (T toElement(MapEntry< String, T> e)) → Iterable<T> -
The current elements of this iterable modified by
toElement
.inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
reduce(
MapEntry< String, T> combine(MapEntry<String, T> value, MapEntry<String, T> element)) → MapEntry<String, T> -
Reduces a collection to a single value by iteratively combining elements
of the collection using the provided function.
inherited
-
remove(
dynamic value, {bool notify = true}) → void -
Removes a single item from the list.
override
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
replace(
T item, {String? key, bool notify = true}) → void -
Updates the value of
item
.override -
serialize(
) → Map< String, dynamic> -
Serializes all of its items into a single map.
inherited
-
singleWhere(
bool test(MapEntry< String, T> element), {MapEntry<String, T> orElse()?}) → MapEntry<String, T> -
The single element that satisfies
test
.inherited -
skip(
int count) → Iterable< MapEntry< String, T> > -
Creates an Iterable that provides all but the first
count
elements.inherited -
skipWhile(
bool test(MapEntry< String, T> value)) → Iterable<MapEntry< String, T> > -
Creates an
Iterable
that skips leading elements whiletest
is satisfied.inherited -
take(
int count) → Iterable< MapEntry< String, T> > -

count
first elements of this iterable.inherited -
takeWhile(
bool test(MapEntry< String, T> value)) → Iterable<MapEntry< String, T> > -

inherited
-
toString(
) → String -
