IList<T>.withConfig constructor
IList<T>.withConfig (
- Iterable<
T> ? iterable, - ConfigList config
Create an IList from any Iterable and a ConfigList.
Fast, if the Iterable is another IList.
If iterable
is null, return an empty IList.
Implementation
factory IList.withConfig(
Iterable<T>? iterable,
ConfigList config,
) {
return ((iterable is IList<T>) && (iterable.isOfExactGenericType(T)))
? (config == iterable.config)
? iterable
: iterable.isEmpty
? IListImpl.empty<T>(config)
: IListImpl<T>._(iterable, config: config)
: (iterable == null)
? IListImpl.empty<T>(config)
: IListImpl<T>._unsafe(LFlat<T>(iterable), config: config);
}
