ReactiveSet<E>.wrap constructor
ReactiveSet<E>.wrap (
- Set<
E> set
Makes any set reactive by wrapping it.
If the argument is already a subclass of ReactiveSet, returns the argument.
Example
import 'package:kind/kind';
void main() {
final nonReactiveSet = <String>{'a', 'b', 'c'};
final reactiveSet = ReactiveSet<String>.wrap(nonReactiveSet);
// ReactiveSystem can observe the read event.
reactiveSet.first;
// ReactiveSystem can observe the write event.
reactiveSet.add('added value');
}
Implementation
factory ReactiveSet.wrap(Set<E> set) {
if (set is ReactiveSet<E>) {
return set;
}
return _ReactiveSet(set);
