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