Methods

any(bool test(K key, V value)) → bool

Available on BuiltMap<K, V>, provided by the BuiltMapExt extension

Checks whether any entry of this map satisfies test.

every(bool test(K key, V value)) → bool

Available on BuiltMap<K, V>, provided by the BuiltMapExt extension

Checks whether every entry of this map satisfies test.

firstWhere(bool test(K key, V value), {MapEntry<K, V> orElse()?}) → MapEntry<K, V>

Available on BuiltMap<K, V>, provided by the BuiltMapExt extension

Returns the first entry that satisfies the given predicate test. Iterable.firstWhere

firstWhereOrNull(bool test(K key, V value)) → MapEntry<K, V>?

Available on BuiltMap<K, V>, provided by the BuiltMapExt extension

fold<T>(T initialValue, T combine(T previousValue, MapEntry<K, V> entry)) → T

Available on BuiltMap<K, V>, provided by the BuiltMapExt extension

Reduces a map to a single value by iteratively combining elements of the map using the provided function.
