filter method
Call the given predicate on each key-value pair in the collection and for each pair that it returns true, add the key-value association in a new Map.
Unlike Iterator#filter, this returns a Map, not an Iterator. @expose @param {function(KeyValuePair.<K,V>):boolean} pred This function must not have any side-effects. @return {Map.<K,V>}
Implementation
_i3.Map<K, V> filter(_i2.bool Function(_i3.KeyValuePair<K, V>) pred) =>
_i4.callMethod(
this,
'filter',
[_i4.allowInterop(pred)],
);
