ListAdapter<E> class

A TypeAdapter that adapts a raw Object into a strongly typed List of type E.

Jetleaf’s conversion service may return values like Iterable<Object>, List<Object>, or ArrayList, which may represent a sequence of values. This adapter ensures that the raw input is converted into a Dart List<E>.

• If source is null, an empty list is returned.
• If source is a List, it is directly converted using List<E>.from.
• If source is an ArrayList, each element is cast and added to a new list.
• Otherwise, an IllegalArgumentException is thrown.

Example

final adapter = ListAdapter<int>();
final list = adapter.adapt([1, 2, 3]); // [1, 2, 3]

final rawArrayList = ArrayList()..addAll([10, 20, 30]);
final adapted = adapter.adapt(rawArrayList); // [10, 20, 30]

final empty = adapter.adapt(null); // []
