MapUtils<K, V> extension

on

• Map<K, V>

Methods

compact([bool newMap = false]) → Map

Remove all entries that value is null

containsKeys(List<Object> keys, {ContainsKeysRules rule = ContainsKeysRules.none}) → bool

Return true if map contains all keys in list of keys

diff(Map to, [bool skipNested = false]) → Map

Returns a new map contend only difference between maps to Map to compare skipNested If true will skip any nested map and only process if maps is equals. Defaults value is false.

doIfContains<X>(dynamic key, {required X doWork(dynamic key, dynamic value), X elseIf()?}) → X?

Return a result of doWork if a map contains a key or return a result of elseIf if non null else will return null

putIfAbsentAsync(String key, Future<V> ifAbsent()) → Future<V?>

Return a value if it exists in map or call ifAbsent that's return a new value and insert him on map

reduce<Tp>(ReduceFunction<Tp> reduceFunction) → Tp?

Reduce

removeKeys(List keys, [bool recursive = false]) → void

Remove all values that matches in list of keys

removeKeysExcept(List keys, [bool recursive = false]) → void

Remove all values except that matches in list of keys

trim([bool newMap = false]) → Map

Apply trim in all String values on tree
