Methods

add(K key, V value) → Map<K, V>

Available on Map<K, V>, provided by the MapAddExtension extension

New map with key set to value. params.add("page", 2)
addAll(Map<K, V> other) → void
Adds all key/value pairs of other to this map.
override
addEntries(Iterable<MapEntry<K, V>> newEntries) → void
Adds all key/value pairs of newEntries to this map.
override
addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
assignAll(Map<K, V> items) → void
Replaces every entry and notifies once.
call([Map<K, V>? newValue]) → Map<K, V>
Sets the value like a function and returns it. count(5)
override
cast<RK, RV>() → Map<RK, RV>
Provides a view of this map as having RK keys and RV instances, if necessary.
inherited
clear() → void
Removes all entries from the map.
override
containsKey(Object? key) → bool
Whether this map contains the given key.
inherited

inherited
deepMerge(Map<K, V> other) → Map<K, V>

Available on Map<K, V>, provided by the MapAddExtension extension

New map where other wins and nested maps are merged too. defaults.deepMerge(overrides)
dispose() → void
Discards any resources used by the object.
inherited
forEach(void action(K key, V value)) → void
Applies action to each key/value pair of the map.
inherited
getOr<T>(K key, T fallback) → T

Available on Map<K, V>, provided by the MapAddExtension extension

Value of key as T, or fallback when missing or another type. json.getOr<String>("name", "")
map<K2, V2>(MapEntry<K2, V2> transform(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
notifyListeners() → void
Call all the registered listeners.
inherited
omit(Iterable<K> keys) → Map<K, V>

Available on Map<K, V>, provided by the MapAddExtension extension

New map without the listed keys. user.omit(["password"])
