-/**
- * An implementation of [List] that delegates all methods to another [List].
- * For instance you can create a FruitList like this :
- *
- *     class FruitList extends DelegatingList<Fruit> {
- *       final List<Fruit> _fruits = [];
- *
- *       List<Fruit> get delegate => _fruits;
- *
- *       // custom methods
- *     }
